Profile:

A high-precision, portable integrated tester with a built-in variable-frequency power module and DSP processor. It uses frequency conversion and digital filtering to avoid power frequency interference, supporting intelligent measurement and data export.

Features:

  1. Large full-touch LCD with graphical interface, enabling one-key operation and no extra professional training required.
  2. Variable frequency technology (45Hz/55Hz etc.) and digital filtering ensure strong anti-interference performance in harsh environments.
  3. Professional DSP high-speed processor enhances computing capacity for fast and accurate measurements.
  4. Full-process intelligent monitoring: automatically adjusts output current, completes testing without manual intervention, measuring Z, R and X.
  5. Mass data storage: saves 100 groups of results with time stamps, supporting review, printing and USB flash drive export.
  6. PC data processing: exported data can be queried and managed on PC for convenient analysis.
