- Model MI 2124
Earth Resistance / True RMS Current Test Set
|
|
Description |
|
The MI2124
is a lightweight and portable Earth resistance and True RMS
Current measuring test set. This unit also provides specific
earth resistance (ρ) measurements.
- Tests include: 2-pole, 3-pole, or 4-pole earth resistance
measurements
- Selective Earth resistance measurements with clamp (no
influence from parallel earths)
- Two clamp earth measurement for quick testing in urban
areas
- Warning indicators for out of limits results and incorrect
test conditions
- Internal memory for up to 1000 measurements
- PC software available – provides easy and fast arrangements
of results
- Battery operated
- 3-Year warranty
