2. If the instrument fails, please call full-time maintenance personnel or send it back to our company for repair. Do not open the instrument by yourself. Otherwise, our company will not be responsible for the loss.
3, insulation resistance tester is stored in a dry, dust-free, non-corrosive gas environment.
4. After confirming that the wiring is correct (Note: The test line is not allowed to ground), turn on the test. The “high voltage output†light indicates that there is a high voltage output. Do not touch the high voltage wire at this time! During the test, it is forbidden to insert or remove the test line or short-circuit the output, so as not to endanger the human body and damage the instrument.
5. When testing large-capacity capacitive loads, ensure that there is enough discharge time after the test. Discharge the test leads after discharging. (The best capacitive load discharge is better than 1 minute)
6. When using the Insulation Resistance Tester, the internal battery displays dim or the power is not displayed during the measurement, indicating that the battery power is insufficient and the instrument should be closed and charged in time. If the visibility is appropriate, turn off the backlight of the LCD (press the "Backlight" button on the keyboard) to save battery power. (Note: If the test shows that the voltage exceeds the selected rated voltage, and if it can not be stable for a long time, please disconnect the device under test to see if the voltage is normal. If it is not normal, please charge it. The charge is full of empty test voltage again, and the voltage is normal. Insufficient to charge in time.)
7. The measured value of the insulation resistance measured when the meter is not connected to the test object generally reaches the T level (1T=1000G). This value is generally a random infinite value. As the test air, it does not have practical significance.
Insulation resistance tester precautions
The use of insulation resistance tester Note 1, insulation resistance tester should not be used for a long period of time when the battery is charged (once a month). Keep the instrument off when not in use and on charging.
