 Test voltages: 50 V, 100 V, 250 V, 500 V and 1000 V
 Accuracy of generated voltage (Robc []  1000*U
N
[V]): -0+10% from the set value
 Detection of a dangerous voltage before commencing a measurement
 Discharging the object tested
 Measurement of insulation resistance with the use of UNI-Schuko plug (WS-03, WS-04) be-
tween all three terminals (U
N
=1000 V is not available)
 Insulation resistance measurement for multi-wire cables (max. 5) using an optional external
adapter
 Measurement of voltage on terminals +R

 Test current < 2 mA
Remark:
With regard to measurements conducted with the use of WS-03 and WS-04 leads, if at
least one out of three measurements has ended with current limitation (LIMIT symbol
is displayed), the results of remaining measurements may be burdened with additional
uncertainty.
