Profile:

A safe, low-power tester using stable low-frequency signals to diagnose multi-point grounding without affecting system operation. Equipped with high-precision clamp meters, it analyzes currents, displays waveforms and direction, and provides sound-light alarm for on-site maintenance.

Features:

  1. Multi-point grounding fault analysis by current detection of grounding loops to judge fault existence.
  2. Real-time display of signal current, grounding shunt current and other branch current values.
  3. Signal current waveform display for measured grounding loops during detection.
  4. Fault direction indication for multi-point grounding in the measured circuit.
  5. High-precision AC/DC current measurement with optional clamp meters.
  6. Intelligent signal current output with power <0.05W to ensure DC system safety.
  7. Ergonomic design, friendly interface, compact structure and easy portability.
  8. Industrial-grade design with imported components for high reliability.
  9. Strict quality control system ensuring stable and high-performance operation.
