Measurement tolerances
Accuracy in ±(% of read-off + number of digits = dgt(s) )
Accuracy is 1 year at a temperature +23°C ±5°C and relative humidity less than 75
%. Warm-up time is approx. 1 minute.

Important!
The measurement functions transistor test and diode test/conti-
nuity check are not protected against overload or excess volta-
ge(s).
Exceeding the max. permissible input parameters may result in
damage to the measuring device and/or is a potentially lethal
hazard to the user.
