• Impulse Earth measurement 10/350 µs.

Key features

• Possibility of performing all types of earth measurements with a single instrument.
• Analysis of earth impedance as a function of the frequency due to a wide measurement frequency band (55 Hz ... 15 kHz).
• Earth measurements on pylons with protective earth cable connected.
• Measurement on mono towers and 4-leg tower.
• A wide variety of measuring clamps: from iron clamps to flex clamps with 10 m length.
• HF-Earth resistance measurement (acc. to IEEE_Std 81).
• Sweep mode Z(f) on screen.
• 3.4’’ colour LCD display with touch screen.
• Floating Mains (universal 90 … 260 V AC) or battery powered (built in fast charger).
• High degree of protection: IP 65 case closed, IP 54 case open.
• Checkbox - different self-check methods.
• DC resistance measurements.
• Impulse impendance measurement for simulating the lightning strike.
• Support for single or automated measurements.
• PC SW for measurement pre and post processing: preparation of the test structure, result download, tree-view, table view and graphical view, storing and printing.
