How Do You Check Amps With A Multimeter. How to test a fuse with a multimeter. The black probe must go into the common socket sometimes labeled COM.

How to Measure Resistance with a Multimeter. The current flows through the multimeter which displays the current. It should show zero ohms.
Turn the big rotary dial to the amperage setting that corresponds with the socket youre using.
When the leads are separated the reading should be 1. Ensure that the current is in the range of mA expected and then lower the setting of your multimeter to the next-highest option for a 005 A or 50 mA current choose 200 mA to get a precise reading in milliamps. When the leads are separated the reading should be 1. The red one goes in the socket labeled A.
