ELECTRICAL SPECIFICATIONS
The measurement accuracy depends on the measurement conditions.
•
The accuracy of measurements is guaranteed under the following
conditions :
- Temperature :
23°C ± 5°C
- Humidity :
80% RH maximum (without condensation)
- Zero adjustment : after adjustment of the zero / compensation for
each range.
•
Resistance measurement :
- Temperature coefficient: (±0.1% of reading ± 0.5 digits) / °C
- Frequency of measurement current: 1kHz ± 10%
- Measurement voltage: 1.5mVAC
