Description
Features:
1. Covers IR/DAR/PI/DD/SV full-function test modes and realizes dual-mode calculation of DAR absorption ratio;
2. The three-in-one operation matrix of key control, touch screen, and knob and mouse greatly simplifies the operation link and makes testing more flexible and faster;
3. Multiple voltage ranges can be switched at will, and customized voltage modes are supported;
4. Real-time recording and visual presentation of insulation resistance-voltage-current time curve, supporting transient analysis of insulation status;
5. Equipped with AC and DC voltage measurement functions, which can automatically identify voltage types and measure AC frequency;
6. Equipped with cable length measurement function and equipped with controllable hardware and software filters, the anti-interference performance is significantly improved.
7. The three major safety barriers of independent discharge circuit, test sample breakdown protection, and arc detection not only protect the safety of the equipment, but also accurately locate insulation weak points to prevent problems before they occur;
8. Adopt a fully isolated structure for high and low voltage circuits to ensure the safety of operators;
9. With USB storage function, data can be exported to U disk in batches for easy backup and migration;
10. Supports RS232 (optional RS485) and Bluetooth communication to meet data interaction in different scenarios.
