Basic usage of multimeter - voltage measurement
2.1 Voltage measurement
When measuring DC voltage, firstly insert the black and red test leads into the common port and the V function jack; then turn the rotary switch to V- or mV-position (Note: If the measured DC voltage is unknown, you should first turn the rotary switch Turn to V- position); Finally, connect the two test leads in parallel to the two ends of the electric component or power supply. At this time, it should be noted that the red and black test leads correspond to the positive and negative poles of the electric component or power supply. After the value is stable, the value of the measured DC voltage will be displayed on the LCD.
The measurement method of AC voltage is basically the same as that of DC voltage, the difference is that the knob should be turned to V~ or mV~, and the voltage is not divided into positive and negative during measurement
