Specified accuracy is valid if 3-wire test lead is used while it is valid up to 100 M
if Tip
commander is used.
Specified accuracy is valid up to 100 M
if relative humidity is > 85 %.
In case the instrument gets moistened, the results could be impaired. In such case, it is
recommended to dry the instrument and accessories for at least 24 hours.
The error in operating conditions could be at most the error for reference conditions (specified in
the manual for each function)
5 % of measured value.
