When the insulation resistance tester is working, the high voltage generated by itself is measured by electrical equipment, so we must use it correctly. If it is used improperly, it will cause personal or equipment accidents. The insulation resistance tester is often used by electric workers. One of the instruments, so what are the correct operation steps of the insulation resistance tester? The editor will give you a detailed introduction today.

The first step: instrument calibration and zero adjustment

First, set the function selector switch of the insulation resistance tester to "OFF", use a screwdriver to adjust the zero adjustment button in the center so that the pointer is on the "0" scale;

The second step: battery detection

Adjust the function selection switch to the BATT.CHECK position and press the test switch. If the pointer stays in the BATT.GOOD area or the right side of this area, it means that the battery is in good condition. If it is on the left, it means that the battery needs to be replaced;

Step 3: Protect the port

When testing the insulation resistance of the wire, the combination of the leakage current flowing outside and the current passing through the inside of the insulating object will cause an error in the insulation resistance value. To avoid this error, it is necessary to wrap the protection wire on the leakage current flow part and connect the protection port Then, the leakage current will not flow on the display, and the volume resistance of the insulating object can be tested.

When electric workers use this instrument, they need to follow the instructions and operate them correctly. Only by following the correct operation will they be handy and become better and better in this industry.
