8.2 Differential Leakage Current,
See figure 4.
Attention - The Red or Black 4mm test sockets must not be used
whilst the PrimeTest 200 is performing a leakage test.
Electric Shock Danger.
Attention - before a differential leakage current test is performed on
a Class I EUT the operator must ensure that the EUT has already
passed a Class I safety test.
Attention - An RCD may be triggered if the EUT is defective.
Warning - it is important that the user verifies that an appliance with
moving parts (e.g. an electric drill) is safely mounted to allow
movement without causing damage to equipment or personnel.
8.2.1 Plug the PrimeTest 200 into a mains power socket using the supplied
IEC lead.
8.2.2 Plug the equipment under test (EUT) into the EUT socket 11 on the
front of the PrimeTest 200
8.2.3 Select the differential leakage current test function, on the rotary
switch 10 .
8.2.4 When the button 9 is pressed the PrimeTest 200 checks the wiring
of the power socket being used. If the line potentials are correct then the
LCD will display the symbols PE and PN in the steady
state. Where a fault exists, then the appropriate symbol will flash (see
Appendix 2) along with the symbol being displayed in the steady state.
A fault condition will inhibit the differential leakage current test.
If a power test is selected but the mains supply has not been
connected to the PrimeTest 200 then PE and PN symbols will
flash and the test is inhibited.
8.2.5 To start the differential leakage test, press the button 9 . Mains
power is applied to the EUT for a period of 2 seconds.
8.2.6 Where a longer differential leakage test is required the operator must
press and hold the button down, them simultaneously press the lock
button down. Mains power is applied to the EUT for a period of up to
30 seconds. The operator can deactivate the mode and end the test
by pressing the button.
8.2.7 The large digital display 2 indicates the differential leakage current, in
mA, the small digital display 3 indicates a PASS/FAIL status. An
additional visual display of a
✓ or ✗ also indicate the PASS/FAIL status.
8.2.7A Schuko Version. The small display 3 will show 1-2 to indicate that the
first in a sequence of two differential leakage measurements is being
recorded. The large display 2 indicates the differential leakage current,
in mA, the small display 3 will revert to indicating a PASS/FAIL status.
An additional visual display of a
✓ or ✗ also indicate the PASS/FAIL status.
8.2.7B Schuko Version. If the result is a FAIL then the test is terminated else
a PASS condition allows the test to continue. The operator again presses
the button. The small display 3 will show 2-2 to indicate that the
second in a sequence of two differential leakage measurements is being
recorded. The large display 2 indicates the differential leakage current,
in mA, the small display 3 will revert to indicating a PASS/FAIL status.
An additional visual display of a
✓ or ✗ also indicate the PASS/FAIL status.
8.2.8 The differential leakage current will remain displayed until another rotary
switch or push button action.
