Measurement category: CAT III (300 V)
Enclosure: IP20
Dimensions 158 × 75 × 35 mm
Weight: 200 g (batteries included)
Accuracy
Accuracy is defined for the period of one year since calibration of
the device at 18 °C to 28 °C with relative humidity of up to 75 %.
Measurement accuracy is stated as: ± [(% of reading) + (least
significant digit)].
