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.
