Measuring tolerances
1
Accuracy in ± (% of reading + display error in counts (= number of smallest points)). The accuracy is valid for one
year at a temperature of +23 °C (± 5 °C), and at a relative humidity of less than 75 %, non-condensing. Temperature
coefficient: +0.1 x (specified accuracy)/1°C
The measurement may be impaired if the device is operated within a high frequency, electromagnetic field strength
> 1V/m. At an electromagnetic field strength <1V/m, a tolerance of +5% must be applied to all specified areas.
max. 70 mA (continuity test / display illumination)
Standby (automatic power-off) approximately 0.5 μA
+29 to +40 °C (≤75% RH non-condensing)
+41 to +50 °C (≤45% RH non-condensing)
