7.3.1 System Data
The device version and serial number are listed under <Setup> / <System Settings> /
<System Data>. The duration of the individual test procedures (standard = 5 sec.) is determined by
the test time. The safety shut-off terminates a test procedure (standard = 30 sec.).

Mains pole reversal ON: On the test socket, L and N are interchanged.
Buzzer ON: Acoustic signal in case of faults
Short-circuit test ON: Whenstartingthetest,rstcheckforshort-circuit.
Standard test procedures:
Automatic test procedures complying with DIN VDE
0701/0702/0752 are activated.
Custom test procedures:
Customized test procedures are activated. Customized test pro-
cedures are stored on the SD memory card.
Test repetition ON:
This mode allows measurements of several measuring points by
means of the test cable (probe). It can be used for measuring
RPW, RISO (protection classes II/III), Icont, Ileak and IPLeak.
The corresponding maximum and minimum value of all measure-
ments will be stored.
Database backup ON:
The device automatically creates up to 5 backups for each data-
base, e.g. Database name_backup.001.

RPE data (resistance measurement of the PE conductor):
RPE VDE 701-702 = resistance for a cable length of 5 m and 1.5mm²
RPE VDE 751 = resistance for a cable length of 5 m and 1.5mm²
RPE per 7.5 m line length = additional resistance per 7.5 m line length

Ua data (measurement on PELV / SELV devices):
Max. output voltage = max. output voltage for PELV / SELV devices
Cable data (cable measurement):
Line length = simple line length
Cross-section = cross-sectional area of the conductor
Conductor qty. = conductor quantity (for total length)
