The megohmmeter under UHV power can help many power workers conduct various power tests more conveniently.

Adjustable high-voltage digital megohmmeter is a small instrument commonly used in power testing and testing. Although sparrows are just small instruments, they are small and complete. The function of the megohmmeter is also very powerful. Here is an introduction by professional technical engineers from Huayi, as well as the operation part of the adjustable high-voltage digital megohmmeter function.

1. L "high voltage output terminal:

This is the end of an LSO southern compilation. A megohmmeter uses high-voltage cables to connect the tested circuit, such as the windings of transformers or motors, as well as the core wires of the cables.

2. G "protection terminal:

When measuring the volume resistance of insulation materials and cables using the three electrode method with a megohmmeter, connect the "G" to the protective ring electrode of the three electrodes. The protective ring is used to eliminate the surface resistance of the measured object and the leakage interference of the measurement circuit.

3. "E" grounding terminal:

The megohmmeter is safely grounded and connected to the zero terminal of the tested object. Water pipes can serve as grounding terminals. The metal casing of the motor, transformer core, and cable shielding layer all belong to the zero end of the tested object. The grounding terminal for artificial discharge is also connected to this terminal.

4. High voltage control button:

A megohmmeter is used to control the test power supply. When pressed, high voltage is output from the "L" terminal.
