• A multimeter is a device that can measure several key details of an electrical circuit. … A modern digital multimeter makes it easy to measure the current flow, expressed in amps; voltage can also be determined. Once the voltage and current are known, you can calculate watts using a simple formula. - Source: Internet
• If you really need to check how multimeter measures voltage on AC circuits, like to see an outlet is ‘ON’ then use an AC tester. The only times we’ve needed to measure AC are when we’ve got an outlet that is acting funny (is it really at 110V?), or if we’re trying to control a heater (such as a hot plate). For messing with AC voltage, my advice is, get yourself a non-contact tester rather than using a multimeter. - Source: Internet

• Once again, turn on your multimeter and set it to its DC voltage range (20V). Repeat this process for all of the connectors that have a black wire (ground) and colored wires (voltage). This time, however, make sure not to touch any of the bare ends of the multimeter probes against anything when they’re inside the PSU’s connectors. Doing so could result in a short circuit or an electric shock if there are problems with what you’re testing. - Source: Internet
• Testing for dead (no voltage) – whenever you isolate a piece of equipment or machinery you should always check that there is no voltage still being supplied to the device. If the machine is powered by an AC voltage you should check that when the isolator or power switch is in the off position there is no incoming supply past the switch. This then means it is safe to continue working on the machine if it is dead. - Source: Internet
