OPERATING MANUAL PAT-1, PAT-2, PAT-2E, PAT-10 version 1.02
The tester will perform the tests in the same way as in the IEC test mode (clause 4.5 of this manual).
Additionally, during the visual inspection, the proper operation of the TEST button on the PRCD
should be checked.
The polarity test and the differential leakage current measurement for PRCD (for PRCD-S al-
so for PE continuity measurement) are carried out with the mains voltage present at the test
terminal.
During the polarity test and the differential leakage current measurement (for PRCD-S also during
PE continuity test), a message saying ‘turn on Prcd’ (turn on PRCD) may turn up on screen. Turn
on the PRCD switch to continue the test.
When measuring the differential leakage current, switch on the PRCD.
In addition to IEC like measurements, the tester will measure the PRCD trip time:
Switch on PRCD. Tester
will commence the first
measurement. If PRCD
trips, a message
prompting to switch on the
RCD will be displayed on
the main screen: 'turn on
PRCD'.
If the PRCD switch is turned on and the message 'turn on Prcd' is still displayed, the PRCD is faulty
(or other circuit element), press the FAIL button to conclude the test.
PRCD must be switched on every time after it
trips. Each consecutive measurement will be
performed automatically. The tester will wait
for 2 minutes for the PRCD to be turned back
on. After this time, when any of the following
occurs: PRCD is not switched on, the circuit
is damaged, the FAIL button is pressed, the
tester indicates lack of continuity on the
measured circuit - the test result will be nega-
tive.
