Always wear appropriate personal protective equipment, including insulated gloves and safety glasses, to guard against accidental arc flashes or shocks. Begin by turning the rotary selector knob to the AC current setting, usually denoted by a capital "A" with a wavy line (~) above it, and the appropriate unit symbol such as "A" or "mA".
How to Measure AC Current Safely and Avoid Meter Damage
Interpreting the Display and Troubleshooting Once the circuit is reconnected and current begins to flow, the multimeter display will show the RMS (Root Mean Square) value of the alternating current, which is the effective value equivalent to DC for heating purposes. While starting high protects the device, reading a small current on a high range often results in a vague, hard-to-read display with low resolution.
Finally, touch the exposed ends of the leads to the two ends of the broken circuit, ensuring a secure metal-to-metal contact to complete the path. This process requires attention to detail and the correct setup to ensure both personal safety and precise readings.

Then, connect the red test lead to the "mA" or "10A" jack on the meter, depending on the expected current, and the black lead to the common "COM" port. The Step-by-Step Measurement Process To measure AC current, you must break the circuit and place the multimeter in series, rather than connecting it in parallel like a voltmeter.
