Feature: 1. Application: Suitable for measuring the insulation resistance of generator, motor, power transformer, wiring, electrical appliance, and other electrical device (such as control, signal, comm, and power cable). 2. Automatic Discharge: When testing the insulation resistance of capacitive load, the charging charge is automatically released after measurement. The discharge status can be confirmed in voltage mode. 3. LCD Backlight Display: This insulation resistance tester adopts an LCD high definition backlight screen, with a 5000 counts display, clear and intuitive, with unit symbol display. You can use it at night or in the dark. 4. High Accuracy: Using panel calibration technology, the instrument is connected to the standard to calibrate and store corresponding data, ensuring that it achieves the required accuracy and performance. 5. Other Functions: The insulation tester supports multiple voltage options and can be replaced at any time. Equipped with a carrying rope, convenient for both hands to operate, saving time and improving efficiency.
