Definition of accuracy
Accuracy in ± (% of reading + display error in counts (= number of smallest points)). The ac-
curacy is valid for one year at a temperature of +23 °C (± 5 °C), and at a relative humidity of less
than 75%, non-condensing. The accuracy is valid after 30 minutes of operating time.
The accuracy can be impaired if the device is exposed to high-frequency or strong electromag-
netic fields.
Field strength (3 V/m): total accuracy = specified accuracy + 5% (of the range)
Field strength (>3 V/m): not specified
