How To Test Dc Amps With A Multimeter. 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. It is relatively easy to measure current using a digital multimeter.
Measuring DC amps with a digital multimeter. Connect the test probes to the circuit. Set the knob to an amp higher than the amp of what you are measuring.
To use the voltmeter function to measure DC volts turn the function switch to V setting.
For measurements of around an amp the resistance of a meter should be much less than an ohm. This will ruin the fuse. Select the DC volts position on your multimeter or the 12V setting if you have a dedicated car battery test range. Select DC or AC on the multimeter.
