How do you use a DC millivolt on a digital multimeter?
Some digital multimeters (DMMs) also include dc millivolts. If uncertain of which to choose, start with dc voltage, which handles higher voltage. First insert the black probe into the COM jack. Then insert the red probes into the V Ω jack. When finished, remove the probes in reverse order: red first, then black.
How do you measure millivolts on a power meter?
Choose the least sensitive millivolt (mV) setting. The least sensitive one will measure the highest number of millivolts. Turn the dial to the section the voltage settings are located. The least sensitive one will measure the highest number of millivolts.
How do you read current on a digital multimeter?
The process for reading current on a digital multimeter depends on your specific multimeter, but it is similar across most devices. Turn on the meter and insert the probes into the appropriate spots.
How do I set the voltage settings on my multimeter?
Plug the black lead wire that comes with the multimeter into the socket on the front of the machine marked COM, which stands for "Common". Plug the red lead wire into the socket marked VΩmA. It is usually the middle one. The top socket, marked 10A is rarely used. Turn the dial to the section the voltage settings are located.
Where is the millivolt setting on multimeter?
Turn the dial to the section the voltage settings are located. The section is usually denoted with the legend V=. There is a selection of sensitivities. Choose the least sensitive millivolt (mV) setting.

Is DC measured in millivolts?
DC millivolts can be used to measure voltage drops across poor connections. To measure DC millivolts you must place the selector switch in the DC millivolt position as shown above. The mV with the horizontal line above it represents DC voltage.
What setting on multimeter is for voltage?
You have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if you've measuring a 12V battery, use the 20V setting.
