WARNING
During measurements of insulation resistance, dangerous voltage up to 500 V
occurs at the ends of test leads of the meter.
It is forbidden to disconnect test leads before the measurement is completed.
Failure to obey the above instruction will lead to electric shock with high volt-
age and make it impossible to discharge the tested object.
Connect WS-03 adapter or
WS-04 adapter with UNI-Schuko
outlet plug.
The meter detects this fact auto-
matically and changes the ap-
pearance of the screen.
