The insulation resistance tester can be used for equipment maintenance in substations and power plants, to measure the insulation resistance, absorption ratio, and polarization index of high-voltage electrical equipment such as transformers, reactors, capacitors, circuit breakers, etc.

1. The instrument has an automatic calibration function. Long press the stop button on the standby interface and follow the information prompt to complete the calibration. This item can be used when the testing accuracy is not accurate enough. [Follow the prompts]

2. The insulation resistance tester is controlled by an 8-bit microcontroller and has a fully Chinese operating interface. It can automatically measure the absorption ratio (DAR) and polarization index (PI); It has functional options such as withstand voltage testing and rapid testing.

3. The output power is high, and the short-circuit current is greater than 5mA, which means the charging current of the load is 5mA.

4. Adopting a new circuit design and introducing digital filtering technology, it has strong anti-interference ability and is suitable for complex high-voltage field measurements.

5. Electromagnetic compatibility design, strong impact resistance, safety compliant plastic shell, easy to carry.

6. Built in high-capacity 2600mAh rechargeable lithium battery pack. Intelligent charging circuit, long battery life.

7. It has fault protection functions such as short circuit, overload, and discharge, and reminds users with sound and text messages.
