6.4.4. Measurement procedure and results of "P-PE" mode
1. Select
P-PE mode by means of the F1 key.
2. Connect the Black, Green and Blue connectors of the three-terminal shuko cable or
of the split cables to the corresponding input terminals of the instrument
B1, B3, B4.
Instrument connection for P-PE test in a 230V
single-phase System
Instrument connection for P-PE in a 400V three-
phase system
Instrument connection for P-PE in a 400V three-phase system without Neutral conductor
3. Connect the shuko plug into a 230V 50Hz socket or the crocodiles to the
conductors of the three-phase system (see previous pictures).
4. The key
F4 permits to select one of the following limit values for the contact
voltage (which can be shown cyclically when pressing the key):
50V
(default).
25V.
5. Press the
START key once to execute a test injecting a current in phase with
positive half wave of the voltage.
Press the
START key twice to execute a test injecting a current in phase with
negative half wave of the voltage.
CAUTION
The P-PE measurement in a 230V System make flow a test current of 6A
approx. This may cause the tripping of magnetic protection switch with nominal
value lower than 10A and
will cause the tripping of RCD device. If necessary
effect the test upstream the switch or RCD.
CAUTION
Never disconnect the test leads when the message
"MEASURING" is
displayed.
