92 Things About How To Read Amperage On A Multimeter | Measuring Resistors In Circuit

  • A multimeter is a handy tool that you use to measure electricity, just like you would use a ruler to measure distance, a stopwatch to measure time, or a scale to measure weight. The neat thing about a multimeter is that unlike a ruler, watch, or scale, it can measure different things — kind of like a multi-tool. Most multimeters have a knob on the front that lets you select what you want to measure. Below is a picture of a typical multimeter. There are many different multimeter models; visit the multimeter gallery for labeled pictures of additional models. - Source: Internet
  • If you were to measure resistance from one end of a wire to another, and if that wire is unbroken, what would you expect the meter to indicate? High or low resistance? It would be low since the wire is continuous. You would read zero or a small fraction of 1. If on the other hand, there is a break somewhere along the line, what would you read? It would be infinite resistance or OL which means overload. - Source: Internet
  • Assuming you followed every step to a tee, the multimeter should automatically display the correct amperage figure. Once you remove the probe (i.e. open the circuit), the number should fall. Always take note of the figure that’s displayed as long as the probe is touching the power source. - Source: Internet
  • Another factor is the frequency of the current. Higher frequencies are more difficult to measure accurately than lower frequencies. Finally, the environment where the measurement is being taken can also affect accuracy. If there is a lot of electrical noise present, it can make it more difficult to get an accurate reading. - Source: Internet
  • If the car is off, a reading of 12.2 V-12.6 V shows that the battery is in good condition and fully charged, and if the measured voltage is less than 12.2 V, the battery is weak and may have to be replaced. - Source: Internet
  • In the figure below, the above steps have been taken, and the multimeter is reading 64.6 mA (milliamps) on its sensitive setting, which is a minor parasitic draw that I’ve simulated by leaving the car’s dome light on. On a modern car with control modules, 70mA is usually considered an acceptable parasitic drain, but less than 30mA is even better. - Source: Internet
  • Do you have a multimeter but are confused about how to use it or are getting unexpected readings? If so, the sections below will help you sort through what to do. If there are words or concepts you do not understand, or symbols on your multimeter that puzzle you, return to the Multimeter Overview tab. If you are looking for multimeter usage ideas or labeled photographs of assorted multimeter models, then visit the other tabs in this multimeter tutorial. - Source: Internet
  • To get started, you should first try to familiarize yourself with a multimeter. Most digital multimeters tend to have the same appearance. They are usually black, and rectangular, and have a screen, buttons, and a probe. - Source: Internet
  • Knowing how to test a battery using a multimeter is important to ensure the battery is working at optimal levels and is not showing symptoms of wearing out. A battery failure can lead to seemingly increasing problems in the hardware of an electronic system or starting troubles in a car. A multimeter can be used to check the voltage and current produced by a cell which helps to recognize a faulty battery that may be replaced. The symptoms of a poor battery and how to test a battery with a multimeter are discussed below. - Source: Internet
  • On Klein devices, you may have to push the red ‘Select’ button if the setting (i.e. Volts, Amps, etc.) bears both the AC and DC symbols. Otherwise, you’ll need to get the amp setting on multimeter to either the AC or DC position. - Source: Internet
    1. If you’re still reading, here’s what you need to do. The ammeter must be placed in series with the circuit to measure current. So the wire feeding the circuit must be opened and the meter probes placed across the gap. For example, if you want to measure the current in a circuit with an outlet receptacle, you could - Source: Internet
  • Voltage is measured across the terminals of the power source (just as measuring the height of the overhead tank). Current is measured inside the circuit (similar to measuring water with a flow meter). Current is measured using an ammeter, which is included in a multimeter. - Source: Internet
  • A typical multimeter should have Red and Black probes. During the configuration, ensure that the black probe is in the “COM” (common) socket. If you don’t see the label “COM” you should proceed to plug the black probe into the port labeled “Negative”. - Source: Internet
  • There are so many electronic gadgets and appliances available these days, designed for a wide range of purposes. The common factor is that they are all powered by electricity. The latter comes in two forms: direct current (DC) and alternating current (AC). The ability to measure these currents is pivotal to identifying issues in an electronic circuit or appliance. We’ll show you how to measure current with a digital multimeter. - Source: Internet
  • Each category on your dial switch might have multiple settings for various ranges (Unless you have an auto-ranging meter. More on that later). If you’re measuring a low-current fuse or a small battery, you might have to switch the dial to a lower range to get an accurate reading. However, if you’re measuring voltage and current from your house outlets, then you’ll want to use a higher range. - Source: Internet
  • You should read 110-120 volts, assuming you’re in the U.S. If so, you’ve just proven you’re receptacle has 120 volts from hot to neutral. Hurray! - Source: Internet
  • The same value might appear differently when measured with a different scale selected on the multimeter dial. For an example, let’s use measuring the DC voltage from a AA battery—which we expect to be 1.5V—using a multimeter that has settings for 200mV, 2V, 20V, 200V, and 600V. When measuring the battery with each setting, we get these readings: - Source: Internet
  • For example, a 9V battery is expected to present you with a constant reading of around 0.9 Amps, while testing an O2 sensor presents a result between 0.2 and 1.5 Amps. - Source: Internet
  • Touch the red lead’s test probe to the terminal post (i.e. the point where you made the disconnect in the circuit), preferably a positive one. The black lead’s probe should connect to the wire that you disengaged to complete the circuit. Now, the multimeter is part of it! - Source: Internet
  • Although they come with two probes, many multimeters have more than two places in which to plug the probes, which can cause some confusion. Exactly where you plug the probes in will depend on what you want to measure (voltage, current, resistance, continuity test, or diode test) and the type of multimeter you have. We have provided one example in the images below—and you can check our gallery for a multimeter similar to yours—but since all multimeters are slightly different, you might need to consult the manual for your multimeter. - Source: Internet
  • The diode check feature is useful to determine in which direction electricity flows through a diode. The exact operation of the “diode check” function will vary for different multimeters, and some multimeters do not have a diode check feature at all. Because of this variety, and because the feature is not required for most Science Buddies projects, we have not included directions here. If you need to do a diode check, consult the manual for your multimeter. - Source: Internet
  • Direct current (abbreviated DC) is current that always flows in one direction. Direct current is supplied by everyday batteries—like AA and AAA batteries—or the one in your cell phone. Most of the Science Buddies projects you do will probably involve measuring direct current. Different multimeters have different symbols for measuring direct current (and the corresponding voltage), usually “DCA” and “DCV,” or “A” and “V” with a straight bar above or next to them. See “What do all the symbols on the front of the multimeter mean?” for more information about the abbreviations and symbols on multimeters. - Source: Internet
  • The configuration process may also include setting the multimeter’s range. This ensures that you get an accurate reading. The range you should set depends on the type of circuit you are measuring the amps for. For example, a range of 10 amps is ideal for measuring a 12-volt battery. - Source: Internet
  • Advanced multimeters might have other functions, such as the ability to measure and identify other electrical components, like transistors or capacitors. Since not all multimeters have these features, we will not cover them in this tutorial. You can read your multimeter’s manual if you need to use these features. - Source: Internet
  • -Turn off the power supply to the circuit: You can only find out the amperage by connecting the multimeter to the circuit. In other words, it should be part of the circuit. So, you should start by turning off the power supply and disconnecting the positive cable from the power source. - Source: Internet
  • Remember, this gallery is meant to be a general guide; if you do not see your model of multimeter pictured here, your best bet is to consult your specific multimeter’s manual. If you need help getting introduced to multimeters in general, refer back to our Multimeter Overview section. If you need to know how to take a specific type of measurement, refer to the Using a Multimeter section. - Source: Internet
  • Get ready! We’re going to start out with the basics of how to use and read a multimeter. When we’re done, you’ll have a firm grasp on the essential functions and benefits of this indispensable tool so you can bang out those projects you’ve been putting off. Or just better understand how to use your multimeter on the job. - Source: Internet
  • Your multimeter probably came with red and black wires that look something like the ones in Figure 4. These wires are called probes or leads (pronounced “leeds”). One end of the lead is called a banana jack; this end plugs into your multimeter (Note: some multimeters have pin jacks, which are smaller than banana jacks; if you need to buy replacement probes, be sure to check your multimeter’s manual to find out which kind you need). The other end is called the probe tip; this is the end you use to test your circuit. Following standard electronics convention, the red probe is used for positive, and the black probe is used for negative. - Source: Internet
  • You will sometimes read that to measure current you need to “splice the meter into the circuit.” It is exceedingly rare that you’ll need to “splice” anything in the sense of cutting a wire. You do, however, need to put the meter in series with the circuit, having all the current flow through the meter as if it’s a wire in the circuit, as depicted in the drawing below. - Source: Internet
  • With those warnings in mind, let’s do a current measurement. Note that we use the words “current” and “amperage” (the unit of current) interchangeably, but the meter’s dial and sockets aren’t labeled with a “C” for current. They’re labeled with the letter “A” for Amperage. - Source: Internet
  • use a multimeter to test electricity from the wall outlets in your home. Electricity from wall outlets is very dangerous and can be fatal. Do not connect the probes directly to a battery or other power supply when you have a “current” measurement setting selected. This will cause a “short circuit” across the battery terminals, and a very high current will flow through your multimeter. This will probably blow a fuse, or possibly damage the multimeter. - Source: Internet
  • These steps pertain to multimeters made by Klein and Fluke. However, they will certainly give you a good gist of how most multimeters work and should be operated. The maximum current that most multimeters can handle is 10A or 20A. Don’t attempt to exceed anything over that figure as doing so will blow the fuse and render the meter useless. - Source: Internet
  • The USB meter can be used for continuous monitoring too. Phones that do not come with LED charging indicators need to be checked by switching on the screen, to see if the charging is complete. A USB ammeter shows the continuous current flowing through the circuit. A high current reading means the phone is still charging; a low one means charging is complete. - Source: Internet
  • Some multimeters also have a diode check function. A diode is like a one-way valve that only lets electricity flow in one direction. The exact function of the diode check can vary from multimeter to multimeter. If you’re working with a diode and can’t tell which way it goes in the circuit, or if you’re not sure the diode is working properly, the check feature can be quite handy. If your multimeter has a diode check function, read the manual to find out exactly how it works. - Source: Internet
  • To measure the current through a lightbulb the multimeter becomes part of the circuit and transfers electricity from the battery to the lightbulb. The positive probe of the multimeter (red) is connected to the positive side of a battery while the negative probe of the multimeter (black) is connected to one lead of a lightbulb. The free lightbulb lead is then connected to the negative side of the battery using wire. Current will flow from the battery to the multimeter and then into the lightbulb. - Source: Internet
  • The left image is a multimeter with no probes inserted. The center image is a multimeter that has a black probe inserted into the center port and a red probe inserted into the right-most port. This setup is rated to measure current under 200 milliamps. The right image shows a multimeter that has a black probe inserted into the center port and a red probe inserted into the left-most port. This setup is rated to measure current up to 10 amps. - Source: Internet
  • Familiarize yourself with the multimeter. Most digital multimeters have a similar look. There are blackjacks for minus or standard wires and three red jacks. One is for measuring voltage and resistance, one is for measuring amperes, and the other is milliamps and microamps. - Source: Internet
  • In most cases, the voltage across a battery can be measured to check if a battery is working or dead. But if the goal is to ensure whether the battery can supply sufficient current to a load, make sure to measure the amperage of the battery in milliampere-hour (mAh). Batteries are rated in amp-hours and voltage. Check the battery’s label to determine the voltage and amp-hours of the battery. For example, 12V 95Ah means the battery provides 12V at 95 Amperes for an hour. - Source: Internet
  • Connect the red and black lead probes to the positive and negative terminal posts respectively. Then, set the multimeter dial to the DC voltage position. Start the car’s ignition, then leave the engine running. In all that time, the voltage reading shouldn’t go below 10. It’s fine if the value’s a bit higher. - Source: Internet
  • Using a clamp meter is the safest and most effective way to measure amperage. This method uses an electromagnetic field to sense the current flowing through a conductor, without coming into contact with the live wire. Clamp meters are available in a variety of sizes and styles, so it’s important to choose one that is appropriate for the job at hand. - Source: Internet
  • What you can do is to use a clamp meter to measure AC currents. The meter uses the electromagnetic field of AC current to measure current, and does not need to be in contact with the wire, so it is safe. The clamp needs to be placed around the wire and the reading will be displayed; it can measure currents as high as 1000A. - Source: Internet
  • The photo below shows the meter measuring current on a small fan in a circuit that we’ve removed from a car for clarity. The positive battery terminal is connected to the positive terminal of the fan. The fan’s negative terminal is connected to the meter’s red lead, and the meter’s black lead is connected to the negative battery terminal. You can’t read the meter’s display, but it is showing about 5 amps. - Source: Internet
  • The voltage that is fed to these appliances varies between 120V and 230V depending upon the standards adopted by different countries. It is important to note that these voltages are high enough to cause injury or even put human life at risk if handled without proper precautions. Since current is measured inside a circuit, it is strongly advisable NOT to use a multimeter when measuring high-voltage AC current. - Source: Internet
  • Now take the black probe and put it in the ground slot, you should read the same value. If so, you’ve just proven you have a clear path to ground. If either of these tests reads less than 110 volts, you now know something is wrong. - Source: Internet
  • You will find a digital LCD display above the dial. It should clearly read the values that you’re trying to measure. Next to, or above the numbers, you should make sure that the display also shows the proper unit symbol (mV, µA, or kΩ for example) for the electrical property you are measuring. - Source: Internet
  • Some multimeters have a continuity check, resulting in a loud beep if two things are electrically connected. This is helpful if, for instance, you are building a circuit and connecting wires or soldering; the beep indicates everything is connected and nothing has come loose. You can also use it to make sure two things are not connected, to help prevent short circuits. - Source: Internet
  • Single-board computers like the Raspberry Pi are also powered by 5V USB. The performance of the Pi is directly affected by the quality of the power supply. You may notice a flashing red light on the Pi board, which indicates an inadequate power supply. With the USB multimeter, you can monitor the voltage and the current going to the Pi, correct the power supply, and extract the best performance. - Source: Internet
  • The range is typical can be extended with the plug-in clamp accouterment. Simply connect the lead generation to the multimeter and connect the other end to the circuit using the multimeter fasteners. Clamp the heated or live wire, which usually is black, red, blue, or another color other than white or green. - Source: Internet
  • If your multimeter is not auto-ranging, you might need to adjust the range. If your multimeter’s screen just reads “0,” then the range you have selected is probably too high. If the screen reads “OVER,” “OL,” or “1” (these are different ways of saying “overload”), then the range you have selected is too low. If this happens, adjust your range up or down as necessary. Remember that you might need to consult your multimeter’s manual for specifics about your model. - Source: Internet
  • Figure 3. The multimeter on the left is manual-ranging, with many different options (indicated by metric prefixes) for measuring different amounts of voltage, current, and resistance. The multimeter on the right is auto-ranging (note how it has fewer options for the selection knob), meaning it will automatically select the appropriate range.

  • Turn off the power before you connect the meter, and use alligator clips! Why is this important? When you use the standard pointy meter leads to complete the circuit when the power is on, all of the current of the circuit will immediately flow through the tiny tip of the probe lead. Due to the small surface area, the probe can heat up and micro-weld itself to what you’re testing. Using alligator clip leads spreads the electrical load over a larger area. Attach them, and then power the circuit. - Source: Internet
  • You might have noticed some other symbols besides V, A, Ω, and metric prefixes on the front of your multimeter. We’ll explain some of those symbols here, but remember, all multimeters are different, so we cannot cover every possible option in this tutorial. Check your multimeter’s manual if you still can’t figure out what one of the symbols means. You can also browse our multimeter gallery to see labeled pictures of different multimeters. - Source: Internet
  • The circuitry in your multimeter being used in the ohms setting is accessing about 3 volts DC from the batteries. If you were to introduce 100 volts through that circuit, you would surely damage something. Most likely you would only blow a fuse. - Source: Internet
  • Instructions for changing the fuse vary with each multimeter model, so you will need to check your multimeter’s manual for instructions. This tutorial from SparkFun provides directions for changing a fuse on their brand of multimeter, but remember that these directions might not apply to your model. Note that in some multimeters-especially in inexpensive ones-you might not be able to change the fuse. - Source: Internet
  • First, we discussed how to use a multimeter for measuring voltage, or simply verifying that voltage is present. Last week, we addressed measuring resistance—verifying that a wire is continuous and not broken somewhere. Today we’re discussing how to use a meter to measure current, also referred to as amperage. - Source: Internet
  • Whenever possible, connect the meter on the ground side of the circuit. It’s the same reasoning you employ when, while replacing the battery, you should always disconnect the negative terminal first and connect it last. For a current measurement, the meter will be in series with the circuit, so the probe leads are as live as any wire in the circuit. If you connect the meter on the ground side of the circuit (as per the illustration above), completing the circuit to ground will cause power to flow if the circuit wasn’t turned off, yet it can’t cause a dead short of a live power wire to ground because the meter is already on the ground side. In contrast, if you connect the meter to the positive side of the circuit and accidentally touch a probe lead to ground, it’ll cause a dead short of power to ground, which is sure to blow up the meter’s fuse or the meter itself. - Source: Internet
  • Most multimeters (except for very inexpensive ones) have fuses to protect them from too much current. Fuses “burn out” if too much current flows through them; this stops electricity from flowing, and prevents damage to the rest of the multimeter. Some multimeters have different fuses, depending on whether you will be measuring high or low current, which determines where you plug the probes in. For example, the multimeter shown in Figure 5 has one fuse for 10 amps (10A) and one fuse for 200 milliamps (200mA). - Source: Internet
  • Most multimeters also use metric prefixes. Metric prefixes work the same way with units of electricity as they do with other units you might be more familiar with, like distance and mass. For example, you probably know that a meter is a unit of distance, a kilometer is one thousand meters, and a millimeter is one thousandth of a meter. The same applies to milligrams, grams, and kilograms for mass. Here are the common metric prefixes you will find on most multimeters (for a complete list, see the References tab): - Source: Internet
  • Are you sure of your multimeter’s maximum amp rating? It’s usually printed on the back of the multimeter. If you can’t find it, consult the manual or the website of the store you purchased it from. Is your power source rated for 10A or 20A or less? Look at the device or gadget’s nameplate to confirm. If you’re checking a car’s battery, look up the specification termed Cold Cranking Amps (CCA, in short). - Source: Internet
  • Note that there’s a way around all of this: You can buy what’s called a “current clamp meter,” which has a set of hinged jaws that surround the cable whose current you want to measure. It then senses the electric field inductively without your having to “splice” the meter into the circuit. These come in a few different flavors. There are clamp meters that only measure current, general purpose multimeters with integrated clamps, and clamp attachments that plug into standard meters. - Source: Internet
  • Old circuit boards are constructed with a lead-based solder, which is toxic. Always wash your hands carefully after handling solder, and check your local waste disposal guidelines to see if there are special rules about disposing of lead as hazardous waste.) Set your multimeter to measure resistance, and have everyone in your house take turns grabbing the metal tips of the probes (one in each hand). Who has the highest resistance? The lowest? - Source: Internet
  • You might be confused by all the symbols on the front of your multimeter, especially if you don’t actually see words like “voltage,” “current,” and “resistance” spelled out anywhere. Don’t worry! Remember from the “What are voltage, current, and resistance?” section that voltage, current, and resistance have units of volts, amps, and ohms, which are represented by V, A, and Ω respectively. Most multimeters use these abbreviations instead of spelling out words. Your multimeter might have some other symbols, which we will discuss below. - Source: Internet
  • Start the car’s ignition, then leave the engine running. In all that time, the voltage reading shouldn’t go below 10. It’s fine if the value’s a bit higher. Assuming the reading doesn’t drop and stays stable, then the battery’s in good condition. Otherwise, if it drops below 10V to, let’s say, 5V, then you may be dealing with a battery that warrants replacing. - Source: Internet
  • Hook the multimeter leads up to a speaker using speaker wire, and set the multimeter to measure AC amps (or AC volts if AC amps is not available). Who can get the multimeter to display the biggest number by yelling into the speaker? (In this case, the speaker is working like a microphone, generating current when it detects sound.) - Source: Internet
  • Always check the multimeter, its slots, and probes for any obvious signs of damage. Never work with broken probes if you value your life! To connect multimeter breadboard for measuring current: insert the black probe into the COM port and the red probe into the mA port. To measure, put the black probe to the negative and the red one to the positive. - Source: Internet
  • You will probably need to open up your multimeter to access the fuses (Important: Always disconnect the probes before you do this). Some multimeters have covers that will pop or slide off, and some have screws that must be removed first. Fuses usually look like small, glass cylinders with metal caps on the end and a thin wire running down the middle: - Source: Internet
  • What Is The Symbol Of Amps On A Multimeter? Amp is represented by “A-” with three dots on the multimeter. In this section, you also see a range of numbers that includes 200μ, 2m, 20m, 200m, and 10A. The “10A” range is the safest of all. What Happens If You Measure DC Voltage With AC Multimeter? If you measure DC voltage on an AC voltage setting using the right polarity, the multimeter presents you with inaccurate results. You get a value of zero (0) when you reverse the polarity. - Source: Internet
  • If you haven’t heard of these terms before, we’ll give a very simple introductory explanation here. You can read more about voltage, current, and resistance in the References tab, above. Remember that voltage, current, and resistance are measurable quantities that are each measured in a unit that has a symbol, just like distance is a quantity that can be measured in meters, and the symbol for meters is m. - Source: Internet
  • A digital multimeter has an LCD, a rotary selector, and ports to connect the probe wires. It is usually powered by a 9V battery. Two probes need to be connected to the respective ports depending upon the type of measurement. The black probe is connected to COM (short for “common”), connected to ground. As for the red probe, for low currents the mA port is used; for high currents, the 10A port is used. - Source: Internet

But for those that do, measuring AC is a similar process as DC; the rotary dial needs to be set to AC, though. - Source: Internet
  • There is one problem with clamp meters, though. The clamp should be placed around only one wire to obtain a reading. But, power cords of appliances are usually a bunch of three wires (live, neutral, and earth). So, a wall socket ammeter would be ideal to measure appliance currents. - Source: Internet

Always wash your hands carefully after handling solder, and check your local waste disposal guidelines to see if there are special rules about disposing of lead as hazardous waste.) - Source: Internet
  • The other complication of measuring current is that most DMMs have multiple ports for current measurement—our DMM has two; they are labeled A and µA mA. The reason for the two ports is because the current through the DMM has to pass through a fuse. If too much current passes through the fuse, it will blow out. Unfortunately the construction of the DMM is such that, if you use a high capacity fuse in the measurement of a small current, you probably won’t be able to read the current value accurately1. - Source: Internet
  • You now know how to measure current with a digital multimeter, and also a clamp meter or USB multimeter. Along with measuring current, a multimeter can be used to measure voltage, resistance, and many other electrical parameters. Learning to use one is the gateway to understanding the world of electronics. - Source: Internet

  • The direction of the current must be accounted for when making a measurement; when you connect your DMM to a circuit, you will be assuming a particular current direction. The sign of the reading displayed on the DMM reflects this assumption—if the actual and assumed directions are the same, the displayed number will be positive. Conversely, if the number displayed is negative, the actual direction is opposite to your assumption. - Source: Internet

  • Many modern gadgets are powered by 5V USB adapters and power banks. It is useful to measure the current to understand the vitals, for example to not overcharge the batteries during charging. This can be done by using a regular multimeter: you can use a USB extension cable, remove the sleeve, cut the positive wire, then connect its ends to the multimeter’s probes and measure the current. However, that’s a cumbersome solution. - Source: Internet

  • Note that whether either of the two amperage sockets have an internal fuse varies meter to meter. On some meters, both are fused. On others, only the high amperage (10A) socket is fused. On many inexpensive meters, neither is fused. This means that if you, for example, connect the meter to a circuit with a 20 amp draw, you can blow up the meter. - Source: Internet
