Here’s the best part — unlike old-fashioned test probes, you can use a clamp meter to get a current reading without breaking a circuit. No shutting off circuits, no cutting into wires — just clamp the meter around a wire and get your reading. In order that the multimeter does not alter the operation of the circuit when it is used to measure current, the resistance of the meter must be as low as possible. For measurements of around an amp, the resistance of a meter should be much less than an ohm.Jun 07, 2021 · How to check battery amps with fluke 88v digital multimeter?
