Further features
| Resistance types |
- Inductive resistances: Coils, transformers, motor windings, twisted cables...
- Non-inductive resistances: Earth bonding, coating, contact résistances, non-twisted cables...
|
| Measurement trigger conditions |
Manual or automatic trigger allowing a single operator to be able to perform measurements |
| EMFs |
Automatic compensation of EMF parasites before each measurement for a greater accuracy |
| Temperature compensation |
- Ambient temperature Tamb, measured with external Pt100 (or entered by the user
- Programmed reference temperature Tref, to which the measured value is converted:
R(Tref) = [R(Tamb) * (1 + α * Tref)] / [1 + α * Tamb]
- Metal material, whose temperature coefficient can be entered by the user (α) |
| Temperature coefficient beyond operating range |
<10% accuracy/°C (from 0 to18°C and from 28 to 50°C) |
| Alarms |
2 programmable thresholds with visuel and sound signal |
