Measurement Functions
Measurements on earthing and lighting protection systems include:
- Standard 4-wire method.
- Standard 4-wire method with current clamps.
- 2-clamp method without junctions disassembling.
Specific earth resistance (soil resistance) measurement with:
- 4-wire method up to 30 meters deep.
- True RMS current measurement.
|
Earth Resistance Measurement
- 2-pole, 3-pole, 4-pole earth resistance measurements.
- Selective earth resistance measurement with clamp (no
influence from parallel earths).
- Two clamp earth measurement for quick testing in urban areas.
Specific Earth Resistance (Φ)
Measurement
- True RMS current measurement for determining problems on earth
systems and conductors.
- Outstanding features even in presence of mains interference
and high probe resistance.
- Warnings indication for out of limits results and incorrect
test conditions.
- 1000 memory locations and PC Software for print-out of
measurement protocol.
- Socket for external battery charger.
- Auto power-off.
