8. Instructions on the use of meters
8.1. Instructions on the use of megohmmeter:
Usage and precautions of insulation resistance tester:
Insulation resistance meters, also known as tramegger or megohmmeters, are special instruments used to measure
large resistance and insulation resistance. It consists of a hand-cranked generator and a magnetoelectric ratiometer.
The hand-cranked generator provides a portable high-voltage measurement power source with a voltage range
between 500-5000V. At present, electronic insulation testers are used. Commonly used insulation resistance meters
have rated voltages of 500V, 1000V, 2500V and so on. Its scale unit is expressed in "Megohms" (M
Ω).
Use of insulation resistance meter
The resistance test can only be performed on the circuit that is not energized. If the test is performed on the circuit
that is energized, the insulation tester may be damaged.
1. Insert the test probe into the V and COM (common) input terminals on the meter.
2. Turn the rotary switch to the required test voltage range.
3. Connect the probe to the circuit under test. The tester automatically detects whether the circuit is energized.
4. Press and hold the test button to start the test. The auxiliary display position displays the test voltage applied to the
circuit under test. The high-voltage symbol (

) is displayed on the main display and the resistance is displayed in
M
Ω
or G
Ω.
5. For detailed usage, please refer to the user manual of the insulation tester.
8.2. Test method of multimeter:
The use method of the multimeter is the same. After getting the multimeter, first install the battery to the multimeter
