AC Voltage Test
Input instrument AC voltage cannot exceed 750V
。
When measuring, turn the rotary switch to the gear
position, connect
the green lead to the V terminal, the black lead to the COM, and the LCD
displays the real-time AC voltage value.

Insulation Resistance Test
Insulation resistance test can only be carried out on an
uncharged circuit. Before testing, check whether the test
circuit wiring is in good condition and whether the circuit under
test is energized. If the circuit is live, it may damage the
instrument and affect the measurement accuracy.
Must wear high-voltage insulating gloves to operate.
In the insulation resistance range, press the test switch to
generate high voltage in the test line head and in the circuit
under test. Please be careful to avoid touching.
Be sure to connect the grounding wire (black) to the grounding
port of the circuit under test.
Do not touch the circuit immediately after testing. The stored
charge may cause electric shock.
