Select the insulation test voltage with the rotary switch
€
Connect test leads and check for external voltages.
If the external voltage is greater than 10% of the test voltage, it is not
possible to make an insulation test for safety reasons

Press the key until the displayed insulation resistance value is stable.
Pressing the START button for more than 10 seconds enables continuous
insulation resistance measurement
Attention: The
ACTIVE
announciators indicate that the instrument is
outputting dangerous high voltages
