Insulation Test (R
ISO
)
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 Class I
appliances that failed the bond 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 under
test (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.
Note
The insulation test may be not suitable for some types of
appliances. For these appliances an alternative test may
be conducted such as a touch current, leakage current,
or suitable leakage current test. It is essential to refer to
standards and/or reference material for the safe
applicability of these alternative tests.
To perform the Insulation test, do the following:
1
Connect the appliance and the probe as
indicated on the tester, see also Figure 5.
For Class I appliances no probe is required.
For Class II appliances apply the probe to
any exposed metalwork on the appliance.
