Correct operation method of digital multimeter to measure voltage: -- AC voltage measurement method
1) Insert the black test lead into the COM jack and the red test lead into the V/Ω jack.
2) Set the function switch to the AC voltage range V ~ range, and connect the test pen to the power supply or load to be tested. The test connection diagram is the same as above. When measuring AC voltage, there is no polarity display.
When using the digital multimeter, please refer to 1.2.4 for DC voltage. "" means do not input a voltage higher than 700Vrms, it is possible to display a higher voltage value, but there is a risk of damage to the internal circuit.
