 Earth
resistance measurementMI2124
- 2-pole, 3-pole, 4-pole earth resistance measurements
- Selective earth resistance measurement with clamp (no influence from
parallel earths; no opening of rust junctions is needed).
- Two clamp earth measurement for quick testing in urban areas (no opening
of rusty junctions).
Specific earth
resistance (p) 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.
