Measuring accuracy
The measuring accuracy is specified as the sum of the following:
• Relative part of the measured value
• Number of digits (counting steps of the last digit)
The stated measuring accuracy is specified for 1 % to 100 % of the final measuring range value
and applies at a temperature of 23 °C ±5 °C and a relative air humidity lower than 80 %. 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]
