Touch Current Test (I
TOUCH
)
Warning
NEVER carry out this test unless you have first
carried out a thorough visual inspection,
followed by a test of the earthing (Class I
appliances), and then a test of the insulation. You
must verify that these tests are passed before
engaging this test.
Caution
Live test! The appliance will be energized at
mains voltage. For this purpose, switch on the
appliance. Appliances driven by motors or
equipped with heating units may present a
danger for the person testing (comply with the
appliance instruction manual!). Please ensure
that the appliance is in a safe condition to run
and secure prior to testing.
The Touch Current test consists of:
• a fuse and L-N loop pre-test
• a leakage current measurement with approximately
2 k resistance connected between earth and
exposed conductive parts on the appliance via the test
probe. The measurement is performed by the direct
measurement method.
To perform the Touch Current test, do the following:
1
Connect the appliance and the test probe as
indicated on the tester, see also Figure 7.
For Class II appliances apply the probe to
any exposed metalwork on the appliance.
For Class I appliances apply the probe to
any exposed metalwork on the appliance
that is not connected to earth.
