This procedure allows you to verify that components receive the correct operating current and diagnose faults related to power delivery. Double-check the range setting before connecting the meter to the circuit.
Digital Multimeter Current Measurement Tips
Preparing Your Multimeter for Current Measurement Before connecting the probes, you must configure the multimeter correctly to handle the expected current. Insert the black probe into the common ground port.
Rotating the selector knob to the "A" symbol, with options for milliamps (mA) or amps (A), prepares the device to measure current rather than voltage. Once the circuit is re-energized, the display will show the current draw.
