To edit parameters press F1 function key first. Use
¿
and
À
cursor keys to select the
parameter you want to edit. By using
½
and
¾
cursor keys adjust the selected
parameter. Press F1 function key again to confirm the selected settings.
Press the START key to perform a measurement.
The measurement can be aborted by pressing STOP key at any time. The actual result
is shown on the display during the measurement. After the measurement time period
has elapsed the last measured value is displayed, and PASS or FAIL indication appears
on the display (based on the high limit current value).

Notes:
Ì
Consider any displayed warning before starting measurement!
Ì
When measuring leakages neighbor magnetic fields and capacitive coupling
(especially from the L and N conductors) can disturb the results. It is
recommended that the clamp is as close as possible to the grounded surface and
away from wires and other objects under voltage or carrying current
Ì
Use test clamp supplied by METREL or other with similar characteristics (current
output, ratio 1000:1, appropriate measurement range; consider error of test
clamp when evaluating measured results)!
6.8 RCD
test
The purpose of this test is to ensure the proper operation of residual current devices
built into an appliances and portable residual current devices.
6.8.1 RCD test on appliances
For the RCD test the appliance must be plugged in the main test socket and the PRCD
test probe must be used. Depending on the type of PRCD, it may be necessary to
manually switch the PRCD on.
During the test the instrument simulates a fault current between the RCDs L (line)
output and the instruments PRCD socket.
