Insulation Resistance Tester

***The Insulation Resistance Tester is specifically designed for laboratory or on-site insulation testing. It includes a high-precision microcurrent measurement system and a digital step-up system. Measurement can be conducted simply by connecting a high-voltage line and a signal line to the test sample. The measurement is automated, with results displayed on a large-screen LCD and stored for future reference.

III. Operational Component Functions

1. L terminal:"L" represents the high-voltage output terminal, known as the line terminal, which is connected to the measured line end via high-voltage cables, such as to the motor winding or the core of a cable.

2. G Terminal:The "G" is referred to as the shield terminal, used for measuring the volume resistance of insulating materials or cables in the three-electrode method, and it is connected to the shielded loop terminal of the three-electrode setup.

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