Bridge Section:
* Adjustable output voltage;
* High accuracy and stability;
* Employs a high-sensitivity amplifier and galvanometer for balance indication;
* Zero-position protection;
* Automatically tests for fault points, but retains manual testing functionality;
* Compared to the wave reflection method, the bridge balancing method has no blind spots, used to identify short cables and breakdown points near the ends.

Withstand Voltage and Positioning Section:
* Automatic overcurrent, overvoltage, and overheat protection;
* Zero-position start protection for enhanced safety and reliability;
* Unique self-discharge design—its own high voltage is zero as soon as the high-voltage output is cut off;
* Dual pointer display for current and voltage, providing clear and intuitive readings;
* One-button switching between positioning and withstand voltage modes for convenience;
* No blind spots in the testing range;
* Adjustable receiver sensitivity for easier positioning;
* Overcurrent protection switch function; convenient use of withstand voltage and positioning modes.
