Gossen MetraWatt ECUTEST ST BASE - Touch Current

Gossen Metrawatt GmbH 31
SECUTEST ST BASE(10) / PRO and SECULIFE ST BASE(25)
13.7 IT – Touch Current
1
Connection also via AT3-IIIE, AT3-IIS, AT3-II S32, AT16DI/AT32DI
2
Only suitable for connecting the DUT to the test socket. Not suit-
able for measurements with AT16DI or AT32DI adapter.
Before conducting any leakage current measure-
ments, make sure that the “Ref. voltage L-PE” and
“Alt. Test Freq.” measurement parameters have been
set correctly in SETUP (see section 12.4).
➭ Connect the DUT to the test socket.
➭ Contact additional, accessible, conductive
parts which are not connected to the pro-
tective conductor with test probe P1.
Meas. Parameter Meaning
Measrement type
Direct P1 Direct measuring method
(via test socket

)
Differential P1 Differential current measurement
(via test socket)
Alternative P1 Equivalent leakage current
method
(via test socket
1
or VL2E)
Perm. connection P1 Permanently installed DUT
Alternative P1–P2 Only test instruments with feature
H01: Equivalent leakage current
measuring method:
2-pole measurement between test
probes 1 and 2 (see section 13.17)
Single fault (SFC) – only with direct measure-
ment type
Normal status Single fault simulation not active
N interrupted Fault simulation – only phase and
protective conductor are con-
nected to the DUT
2
PE interrupted Fault simulation active – the pro-
tective conductor is disconnected
from the DUT for the duration of
the measurement.
Polarity – only with measurement type
direct, differential and AT3 adapter
