Opening the Instrument / Repairs
The instrument may only be opened by authorized, trained per-
sonnel in order to ensure flawless oper
ation and to assure that the
guarantee is not rendered null and void.
Even original replacement parts may only be installed by autho-
rized, trained personnel.
If it can be ascertained that the instrument has been opened by
unauthori
zed personnel, no guarantee claims can be honored by
the manufacturer with regard to personal safety, measuring accu-
racy, compliance with applicable
safety measures or any conse-
quential damages.
If the guarantee seal is damaged or removed, all guarantee claims
ar
e rendered null and void.
Attention!
!
Before opening the housing, pull the mains plug out of
the outlet and wait for at least 5 minutes.
Switching Power Consumers – Course of action
Be absolutely sure to adhere to the sequence specified below
when switching the live device under test. This prevents excessive
wear of the mains relays at the test instrument.
Before measurement:
1) DUT : Turn the DUT off via its own switch.
2) Tester: Switch line voltage to the test socket.
3)
DUT : Turn the DUT on via its own switch.
After measurement:
4) DUT : Turn the DUT off via its own switch.
5) Tester: Deactivate line voltage to the test socket.
Switching Power Consumers – Maximum Starting current
Our test instruments SECUTEST BASE(10), PRO and SECULIFE ST
BASE(25) allow for the active t
esting of devices with a nominal cur-
rent (load current) of up to 16 A.
The test socket of the respective t
est instrument is equipped with
16 A fuses and the switching capacity
of the internal relays also
amounts to 16 A. Starting currents of up to 30 A are permissible.
Attention!
!
In spite of the comprehensive safety measures against
overload, starting currents of more than 30
A may result in
accidental fusing of the relay contacts. In this case, the
following error message appears: 
„L(N) fuse of the test socket is damaged“.
➭ Check the two fuses of the mains connection. Replace them
with new ones if they are damaged.
If the above error message persists, it
may be assumed that the
relays are damaged. In this case, the test instrument must be sent
to our Service Center for repair (address see section 15).
Safer testing with Test Adapter
For devices under test which are expected to feature a starting
current of more than 30 A, we strongly recommend the applica-
tion of a test adapter for higher starting currents: 
e. g. test adapter of the AT3 series 
(AT3-IIIE, AT3-IIS, AT3-IIS32, AT16DI or AT32DI).
Alternative: Passive Testing
On the basis of the hazard assessment, it is also possible to per-
form a passive test (equivalent l
eakage current method) instead,
i.e. without applying line voltage to the test socket.
The test instrument may not be used:
• If external damage is apparent, 
for example if parts which conduct dangerous touch voltage
ar
e freely accessible, 
if the display is broken or defective (in which case dangerous
voltage or mains connection errors might no longer be indi-
cated)
• If the seal or sealing lacquer has been removed as the result
o
f repairs or manipulation carried out by an unauthorized/non-
certified service provider.
• With damaged connection and/or measurement cables and patient
ports, e.g. interrupted insulation or kinked cable
•If the instrument no longer functions flawlessly
• After extraordinary stressing due to transport
In such cases, the instrument m
ust be removed from operation
and secured against unintentional use.
