Four,Operational Component Function

1.L Terminal :"L" is the high-voltage output terminal, also known as the line terminal, which is connected to the line being tested via a high-voltage cable, such as to the motor winding or cable core.

2. G Terminal :The "G" is called the shielded terminal, used for measuring the volume resistance of insulating materials or cables in the three-electrode method. It is connected to the protective ring terminal of the three electrodes.

3. E terminal :"E" is referred to as the earth end, connected to the earth or zero terminal of the item being tested. For example, the metal housing of an electric motor, the iron core of a transformer, or the shielding layer of a cable.

4. Cautionary Notes and Other Information  Please note safety.L is for the high-pressure side! E is for the ground side.MandatoryTouching the ground!
