Insulation Test (RISO)
Warning
•
The test voltage is 500V dc. Do not touch
the appliance during the insulation test!
If the test fails any metal parts of the
appliance could become live!
•
Always make sure that the test has
completed before disconnecting the
appliance leads to ensure that all
capacitances have discharged.
Caution
Do not perform the Insulation test on
appliances that failed the bond test or the
visual inspection test.
The test checks the resistance of the insulation between
•
the earth pin of the appliance cable plug (Class I)
or
•
the test probe to be applied to the appliance (Class II)
and the Live and Neutral pins of the appliance (pins are
connected together within the tester for this test).
The insulation test will be inhibited if the tester detects a
terminal voltage >30 Vrms prior to initiation of the test.
