Key benefits & differentiators

The backlit LCD enables fast on-site readings, while the built-in memory supports value logging during troubleshooting and maintenance tasks. 

  • High-current measurement up to 3000 A AC with a Rogowski coil: ideal for industrial environments.
  • Flexible loop fits where standard rigid clamps cannot—around busbars, thick cables and crowded panels.
  • TRMS measurement for dependable AC readings in real-world electrical loads.
  • Inrush (starting current) for diagnosing motors, compressors, UPS, HVAC systems and equipment with startup peaks.
  • Frequency measurement (50–400 Hz) for quick verification in drives, generators and power systems.
  • Backlit display + auto power-off for convenient field use and longer battery life.

Typical applications

Perfect for electrical maintenance, industrial installations, machine current monitoring, inrush diagnostics, and measurements on large cross-section conductors. The flexible Rogowski coil allows quick placement around the conductor for efficient testing.

Main features

  • Up to 3000 A AC
  • Backlit LCD
  • Inrush function
  • Frequency measurement
  • Easy operation
  • Memory for value logging
