A professional tester for power equipment insulation tests, with 5 adjustable DC output voltages up to 10000V and 5mA short-circuit current. It accurately measures insulation resistance via real-time sampling, supports AC/DC use, and automatically calculates key test indexes for large capacitive loads.

1. High charging current (5mA) ensures accurate absorption ratio testing of large-capacity capacitive samples, overcoming the defects of ordinary megohmmeters.
2. Real-time voltage and current sampling for resistance calculation, ensuring accurate readings even when the voltage changes during testing.
3. MCU-controlled with human-machine interface, portable and easy to operate, with automatic range switching and clear reading.
4. Built-in high-capacity rechargeable battery for AC/DC dual use, equipped with undervoltage and overcharge protection.
5. Fast automatic discharge after testing, real-time discharge process monitoring and residual voltage display for safety.
6. Automatically calculates and displays R15S, R60S, R600S, absorption ratio and polarization index with 600S maximum timing.
7. Stores historical test data and time, with strong anti-interference ability and stable, reliable readings.
8. Complete protection functions and high protection grade, complying with international safety standards for safe operation.
