The digital multimeter must have a current-measuring gear.
Then, insert the test leads into the current-measuring jack on the left, and connect the multimeter to the line to be tested. If you don't know how much current there is, it is best to adjust the gear to a higher gear, and if it is not suitable to lower it by one gear, so as not to burn the watch.
1. Insert the red test lead into the "μ, mA, ℃" or lOA jack, and the black test lead into the "COM" jack.
2. Set the function range switch to μA￣=, mA￣ or A current measurement gear. The default setting is DC current measurement. To perform AC measurement, press SE-LECT blue key to select AC current measurement.
3. When measuring current, the test lead should be connected in series with the circuit under test, and the red test lead should be close to the positive side of the power supply, otherwise "-" will appear in the LCD display (the AC current test lead is not divided into positive and negative).
4. Read the measurement result from the LCD display screen, the value measured by U You OE is the true effective value.
