- 💡Warning: Working with electricity and electrical components can be potentially dangerous. Extreme safety precautions must be followed when taking electrical measurements. Before using a digital multimeter, be sure to read and fully understand the instructions and warnings outlined in the owner’s manual. - Source: Internet
- Digital multimeters are often described as having high precision, but the precision of measurement results themselves does not differ significantly from analog testers. However, in this context, “high precision” refers to the instruments’ ability to accommodate higher resolutions because their digital displays can display more digits. Since analog testers indicate values with a needle, the possibility exists that the person using the instrument will make a mistake when reading the value. Such mistakes are known as reading errors. - Source: Internet
- When using a digital multimeter, it’s important to keep a few safety precautions in mind. One thing to remember is to never operate the multimeter on live circuits. DC and AC currents can be dangerous, so make sure the multimeter is set to measure the correct voltage or current. Always read the multimeter’s manual before attempting to work with electricity. If the multimeter’s display shows a value that is greater than 30 volts, that’s not safe. - Source: Internet

When choosing a digital multimeter, the first step is to ask what functions you wish to use. - Source: Internet
- A digital multimeter is an indispensable tool for testing, diagnosing, and troubleshooting electrical circuits, components, and devices. The first digital multimeter was introduced in the late 1970s, and has proven much more accurate and reliable than the old needle-based analog meters. It’s used primarily to measure voltage (volts), current (amps), and resistance (ohms). But that’s just the beginning of what this surprisingly useful tool can do. - Source: Internet
- Cheaper multimeters can measure the voltage of mains, but we will suggest not to use the multimeter for that purpose as it might be difficult to change the fuse in a $2 multimeter. Other reason not to use is – if your fuse is blown away, probably it can not be replaced. That ~ sign is for alternative current – mode dial’s that V~ is useless in the cheaper multimeter for safety. - Source: Internet
- Check the working voltage of each point and compare it with the normal value. First of all, the accuracy of the reference voltage should be ensured. It is best to use a digital multimeter of the same model or similar for measurement and comparison. Detecting whether the external AC voltage of the electrical equipment and the DC voltage of the internal circuit are normal is the basis for analyzing the cause of the failure. Therefore, in the process of repairing electrical equipment and electronic circuits, the relevant voltage should be measured first. - Source: Internet
- Voltage measurements are all relative to the points being measured. If you put the black probe on the 3.3V header of an Arduino, and the red probe on the 5V header, you will see a reading of 1.7V because that’s the difference between the two points. - Source: Internet
- The function of multimeter to measure voltage, current and resistance is partially realized through the conversion circuit.

These are not the only parameters to look for but are considered the most important ones. For the complete parameter study, you can see this post of mine. - Source: Internet
- To begin, make sure you have the correct voltage and current unit. In the case of multimeters, the unit is indicated by a wavy line or a straight line. In addition, multimeters have three or four ports. A common port is the grounding port, and all meters have one. Usually, you should use the V Omega m-A port, which is geared for testing low-amp currents, and the 10-A port for measuring large-amp currents. - Source: Internet
- Next, turn on the digital multimeter and choose a range that allows you to get the best reading. Most multimeters will have a range that is clearly labeled with the maximum resistance reading, but you should be careful not to exceed it. Also, make sure the probe is attached securely to the object that you’d like to measure. - Source: Internet

- For circuits that are inconvenient to measure current, the voltage at both ends of the resistor is often measured. With the help of Ohm’s law, have indirect current testing to calculate. Such as the transistor current negative feedback in amplifier circuit and the transistor static operating point ICQ of the emitter follower, it is commonly used. However, there is a certain error between the actual resistance value and the nominal value. The resistance value of the resistor will change after long-term use, especially the carbon film resistor. - Source: Internet

Often, they include several additional specialized features or advanced options. Technicians with specific needs, therefore, can seek out a model targeted to meet their needs. - Source: Internet
- If you connect the multimeter leads backwards, it won’t damage the multimeter. It will just show a negative voltage reading instead, because a voltage reading is the difference between the two points being measured. If the red probe is connected to a higher voltage than the black probe, the reading is positive. If the red probe is connected to a low voltage than the black probe, the reading is negative. - Source: Internet
- Multimeters have two voltage measurement types: one for DC voltages, one for AC voltages. For hobby projects you will almost always use the DC range, which has a symbol like “V-”. The straight line indicates DC, which is a flat voltage. The AC range has a symbol like “V~”, which indicates a voltage that alternates between positive and negative. - Source: Internet
- Unlike analog testers, measured values from digital multimeters can be read directly, without the need to interpret fine-grained graduations, and the instruments are easy to read in dark locations. In this way, digital multimeters excel in the ease with which their values can be read*. Some digital multimeters can send data to a computer, further reducing the likelihood of error. - Source: Internet
- Auto-ranging multimeters simply require you to select voltage mode, and they take care of the rest. However, many multimeters don’t have auto-ranging. Instead, they have a number of different voltage ranges that you can select from. The voltage range is the maximum voltage that it will be able to measure and display, so you need to select a range that’s larger than the voltage you expect to see. - 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
- Figuring out the approximate range of the electrical current you’re testing with a manual range multimeter can be a time-consuming process. If you want to test resistance, for example, you must first estimate the approximate ohms (Ω) of the current by turning the dial to a specific ohms range, then keep clicking manually until the multimeter gives you a readout. A multimeter with an auto-range function (available only on digital models) will save time since all you have to do is select the type of test to perform (voltage, resistance, or current). The meter will then automatically detect the correct range by scanning through all the range options until it matches the right range to the circuit, and a readout appears immediately. - Source: Internet
- The next step is to connect the probes to the jacks labeled DC voltage, VO, and common. Then, connect the other probes to the object to be tested. The test is complete if the reading is within the ohm range. You can use this technique for a variety of electrical components, including battery-operated fans and electrical equipment. Alternatively, you can use a multimeter to test voltage and current. - Source: Internet
- To measure the current, plug the red probe to stay on the safe side in the amps (a) slot since we do not know the current value. If we get very low values, we can go to milliamps. To measure a circuit’s current, we need to connect the multimeter in series with the course. - Source: Internet

- If you need to replace a fuse on your digital multimeter, you should first disassemble the device. The fuse is usually in the clear glass case and you need to replace the fuse if the wire inside of it has burnt out. If it is a ceramic fuse, you need to check whether it is damaged or not. In some cases, you can use a soldering iron and wick to repair the connections. - Source: Internet
- As a beginner, you can’t be expected to know everything about electrics, and that is why many digital multimeters have built-in safety protocols. These help to protect the multimeter, the component you are checking, and, most importantly, you. Electricity can be dangerous, so it is important to have a device that can protect you. - Source: Internet
- If you select a range that’s too high or too low it doesn’t matter: you won’t damage the multimeter. If you select a range that’s too low, such as measuring a 5V signal on the 2V range, the display will simply show that it’s out of range. If you select a range that’s too high, such as measuring a 5V signal on the 200V range, the multimeter will give you a reading but it will probably not have the same amount of accuracy and can’t display it to the same number of decimal places. - Source: Internet
- A digital multimeter can be dangerous if it is not handled safely. It is best to use a higher-category multimeter in real-world situations. Increasing the category rating increases the voltage level of the system, so it’s best to err on the side of safety. While testing the multimeter, remember to always wear rubber insulating gloves. Inspect the probes for cracks or deterioration, as these may lead to electrical shocks. - Source: Internet
