Set the multimeter to the correct current range: A, mA, or µA
Move the red probe to the correct current input jack
Keep the black probe in the COM jack
Turn off power to the circuit before connecting the meter
Open the circuit so current must pass through the multimeter
Connect the multimeter in series with the load
Turn the power back on
Read the current value on the display
Start with the highest current range if the current is unknown
Switch to a lower range for a more precise reading if needed
Never connect the multimeter across a power source while set to current mode
Turn off power and remove the meter after testing
Move the red probe back to the voltage jack after finishing
Check the meter’s fuse if no current reading appears
