ā¢ Probe Test
Test the probe after completing each test (see also section 10.2.2).
If the fuse at test probe P1 is defective after testing has
been started, all subsequent measurements conducted
using this measuring path will be incorrectly evaluated as
good!
ā¢ Fuse Replacement
The fuses may only be replaced when the instrument is volt-
age-free, i.e. the instrument must be disconnected from
mains supply power and may not be connected to a measur-
ing circuit. The fuse type must comply with the specifications
in the technical data or the labeling on the instrument.
Opening the Instrument / Repairs
The instrument may only be opened by authorized, trained per-
sonnel in order to ensure flawless operation 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
unauthorized 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
are rendered null and void.
Before opening the housing, pull the mains plug out of
the outlet and wait for at least 5 minutes.
Switching Power Consumers ā Procedure
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
Device under test
:
Turn the DUT off via its own switch.
2 Test instrument:
Switch line voltage to the test socket.
3
Device under test
:
Turn the DUT on via
its own switch.
After measurement:
4
Device under test
:
Turn the DUT off via
its own switch.
5 Test instrument:
Deactivate line voltage to the test socket.
Switching Loads ā Maximum Starting Current
Our SECUTEST BASE(10), PRO and SECULIFE ST BASE(25) test instru-
ments permit active testing of devices with a nominal current (load
current) of up to 16 A.
The test socket on the respective test instrument is equipped with
16 A fuses to this end and the switching capacity of the internal
relays is also 16 A. Starting current of up to 30 A is permissible.
Despite extensive protective measures targeted at pre-
venting overloading, the relay contacts may be welded
together if starting current exceeds 30 A. The following error
message appears in this case.
āL(N) test socket fuse defectiveā.
ā Check both of the mains connectionās fuse links. If theyāre de-
fective replace them with new ones.
If the error message described above still appears, it must be
assumed that the relay is defective. If this is the case, the test
instrument must be sent to our service department for repair (see
section 15 for address.
Safer Testing with Test Adapter
In the case of test objects for which a starting current of greater
than 30 A can be expected, we urgently recommend the use of a
test adapter for larger starting currents:
for example test adapters from the AT3 series
(AT3-IIIE, AT3-IIS, AT3-IIS32, AT16DI or AT32DI).
Alternative: Passive Test
If necessary on the basis of the hazard assessment, testing can
be conducted as a passive test (equivalent leakage current
method), i.e. without switching line voltage to the test socket.
The test instrument may not be used:
ā¢ If external damage is apparent, for example if parts which
conduct dangerous touch voltage are freely accessible, if the
display is broken or defective (in which case dangerous volt-
age or mains connection errors might no longer be indicated)
ā¢ If the seal or sealing lacquer has been removed as the result
of repairs or manipulation carried out by an unauthorized/non-
certified service provider
ā¢
With damaged connection and/or measurement cables and patient
ports, e.g. interrupted insulation or kinked cable
ā¢If the instrument no longer functions flawlessly
ā¢ After extraordinary stressing due to transport
In such cases, the instrument must be removed from operation
and secured against unintentional use.
Meanings of Symbols on the Instrument
The symbols on the instrument have the following meanings:
Warning regarding dangerous electrical voltage
Warning concerning a point of danger
(attention: observe documentation!)
CE conformity marking
This device may not be disposed of with household
trash.

If the guarantee seal is damaged or removed, all guar-
antee claims are rendered null and void.
