Properties
Measuring functions
- Step voltage;
- Contact voltage;
- Specific earth resistance;
- Earth resistance.
Key features
- Accurate: high accuracy of the measurements due to a high current of up to 50 A and effective suppression of noise.
- Noise immunity: excellent immunity even against changing earth currents.
- Autonomous Step Voltage meter: no need for long potential leads; a few meters can be used simultaneously.
- Safe: high safety due to low output voltage (55 V).
- Low weight: the weight of the Station is 29.5 kg only.
- Memory: up to 1000 test results can be saved into the 3-level internal memory of the system.
- PC SW HVLink PRO included in the standard set enables downloading and analysis of results and printing of test reports.
