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 > 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) r5 % of measured value. The insulation resistance results in Autotest may slightly differ in comparison to results in Single test mode because of the three wire connection and the internal resistance of the measuring instrument.
