Insulation Resistance - P - TESTBOY TV 465 PRO Bedienungsanleitung

®
Testboy TV 465
Notes:

When S/EB1 probe is connected during the test then the current through it is also
considered.

Consider any warning on the display before starting the measurement!

Do not touch or disconnect the device under test during the measurement or before
it is fully discharged! The message »Udisch ...« will be displayed while the voltage
on the device is higher than 20 V!

Insulation resistance - P

10.1.14
The insulation resistance test checks the resistance between live conductors and isolated
accessible metal parts of the device under test. This test can disclose faults caused by
pollution, moisture, deterioration of the insulation material etc.
The instrument measures the insulation resistance between:

Main test socket (L+N) and S/EB1 test terminal
This function is primarily intended for testing Class II appliances and Class II parts of Class
I appliance.
