Electrical Measurement Specifications
The accuracy specification is defined as ±(% reading +digit counts) at 23 °C ±5 °C, ≤80 %
RH. Between -10 °C and 18 °C and between 28 °C and 40 °C, accuracy specifications
may degrade by 0,1 x (accuracy specification) per °C. The following tables can be used
for the determination of maximum or minimum display values considering maximum
instrument operating uncertainty per EN61557-1, 5.2.4.
