Measurement tolerances
Specification of precision in +/- (% of read value + display error). The accuracy is valid for one year at
a temperature of +23°C ± 5°C, and at a relative humidity of less than 85 % rF, non-condensing.
The accuracy corresponds to a environmental field strength of < 3 V/m and a frequency of
< 30 MHz.
