Measuring accuracy
The measuring accuracy is specified as the relative part of the measured value (output current).
The specified measuring accuracy applies at a temperature of 23 °C ±5 °C and a relative air
humidity lower than 75 %. In case of deviating temperatures, observe the temperature
coefficient by adding the following value to the specified measuring accuracy:
0.2 [1/°C] x specified measuring accuracy x difference to reference temperature range [°C]
