Note
1 Safety Precautions
SECUTEST ST BASE(10), SECUTEST ST PRO and
SECULIFE ST BASE(25) test instruments are
manufactured and tested in accordance with
the following safety regulations:
IEC/EN 61010-1 / VDE 0411-1, DIN VDE
0404, IEC/EN 61577 / VDE 0413-2,-4 /
DIN
EN 61557-16 / VDE 0413-16
The “automatic test sequences” are semiautomatically controlled sequences whose
progress is interrupted by safety-relevant
stoppages and the associated warnings and
instructions. As a result, the level of protection provided to the user is greater than
demanded by sections 4.1.6 and 4.1.7 of
DIN EN 61557-16 with regard to “automatic
test sequences”.
The safety of the user, the test instrument
and the device under test (electrical equipment or electrical medical device) is only
assured when the instrument is used for its
intended purpose.
Read these condensed operating instructions and the
full operating instructions carefully and completely
before placing your test instrument into service (available at our homepage www.gossenmetrawatt.com for
download). Follow all instructions contained therein.
Make sure that the operating instructions are available
to all users of the instrument.
Tests may only be performed by a qualified
electrician, or under the supervision and
direction of a qualified electrician. The user
must be instructed by a qualified electrician
concerning performance and evaluation of
the test.
Suitable personal safety equipment is
required.
If you use any active or passive implanted
medical devices, please consult your doctor
or the manufacturer of these devices.
Manufacturers and importers of electrical
medical devices must provide documentation for the performance of maintenance by trained personnel.
Observe the following safety precautions:
• The instrument may only be connected to
electrical systems (TN, TT or IT) with a maximum of 240 V which complies with applicable safety regulations (e.g. IEC 60346, VDE
0100) and is protected with a fuse or circuit
breaker with a maximum rating of 16 A.
• Measurements within electrical systems
are prohibited.
• Be prepared for the occurrence of unexpected voltages at devices under test
(for example, capacitors can be dangerously charged).
• Make certain that the measurement
cables are in flawless condition, e.g. no
damage to insulation, no cracks in
cables or plugs etc.
• When using a test probe with coil cord
(SK2W): Grip the tip of the test probe
firmly, for example during insertion into a
jack socket. Tensioning at the coil cord
may otherwise cause the test probe to
snap back resulting in possible injury.
•
Measurement of insulation resistance and
equivalent leakage current
alternative measuring methods)
Testing is conducted with up to 500 V. Current limiting is utilized (I < 3.5 mA), but if
terminals L or N at the test socket are
touched, electrical shock may occur which
could result in consequential accidents.
• During operation with line voltage:
Exposed conductive parts may conduct
dangerous touch voltage during testing.
Do not touch under any circumstances!
Use a special cover in order to avoid
touch contact.
Mains power is disconnected at the
instrument if leakage current exceeds
approx. 10 mA (can be switched to 30
mA). However, this does not fulfill the
requirements specified for a PRCD. If the
“Proceed in case of limit violation” setting
is used, enhanced safeguarding against
touch contact and a 30 mA RCD must
be used, and personal protective equipment (PPE) must be worn (secure workstation).

Attention!
!
Attention!
!
The function test may only be performed after the DUT has successfully
passed the safety test!
• Probe check for probe connector P1: Please
perform a probe check after each test.
If there is a fuse defect in test probe
P1 after having started the test, all
subsequent measurements which
are performed with this measurement path might be erroneously
rated as good!
Fuse replacement
The fuses may only be replaced when the
instrument is voltage-free, i.e. the instrument
must be disconnected from mains supply
power and may not be connected to a measuring 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 personnel 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 authorized, 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 accuracy, compliance
with applicable safety measures or any consequential damages.
Any warranty claims will be forfeited when
the warranty seal has been damaged or
removed.
Switching power consumers (max. 16 A*)
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) Tes te r:
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) Tes te r:
Deactivate line voltage to the test
socket.
* for currents > 16 A AC please use adapter
AT3-IIS32 (Z745X), for example
The test instrument may not be used:
• 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 voltage or mains connection errors
might no longer be indicated)
• If the seal or sealing lacquer has been
removed as the result of repairs or manipulation carried out by a non-authorized/noncertified 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 serious damage due to transport
In such cases, the instrument must be
removed from operation and secured
against unintentional use.

3.1 Mains Connection
Nominal mains values: 100 to 240 V, 50 Hz to 400 Hz
➭ Connect the test instrument to the mains
cable via its inlet plug and insert the
mains plug into an electrical outlet. The
function selector switch can be set to
any position. If a mains outlet (earthing
contact outlet) is not available, or if only a
3-phase outlet is available, the adapter
socket can be used to connect the
phase conductor, the neutral conductor
and the protective conductor. The
adapter socket has three permanently
attached cables and is included with the
KS13 cable set (see wiring diagram in
the operating instructions).
If connection is not possible via an
earthing contact outlet: Shut down
mains power first. Then connect the
cables from the coupling socket to
the mains using pick-off clips in accordance with the diagram. Disconnection from mains power is only
possible with the mains plug.
Measurements in IT Systems
The setting IT system can be activated in
selector switch position SETUP (Setup 1/3)

6 Internal Database
6.1 Creation of Test Structures
A complete test structure with data regarding
customers and devices under test be created
in the test instrument. This structure makes it
possible to store the results of single measurements or test sequences of test objects
belonging to various customers. Manual single
measurements can be grouped together into a
so-called “manual sequence”.
Up to 50,000 data records can be stored in
the test instrument. The following applies in
this regard: 1 data record = 1 DUT or location node or customer or individual measurement.
A complete description of database creation is
included in the full operating instructions for
your test instrument.
6.2 Export – Transmission and Storage of Test Structures and Measurement Data
Structures set up in, and measurement data
saved to the test instrument can be imported
to the IZYTRONIQ report generating software
via a plugged-in USB stick (PRO and/or Feature KB01 only) or via the USB slave port.
Data can then be saved to the PC and
reports can be generated.
Data transfer to IZYTRONIQ should not
be started during single measurements or test sequences.
Furthermore, you can save the database to
a plugged-in USB stick for subsequent
restoring to the device memory.
6.3 Import (PRO and/or Feature KB01 only)
The test structures created at the PC with
the help of the report generating software
can be loaded into the test instrument via an
USB stick or via the USB slave port.

Procedure for measuring with save function and
pre-selection of the (ME) device
If you’d like to save your single measurements to selected (ME) devices in a database (see section 6), the following procedure
is advisable.

ber for the following measurements
with the scroll keys.
3 Return to the measuring view by
pressing the ESC key or the START/
STOP key.
4 Start the test with the START/STOP
key before switching the DUT on
The measured value recording
symbol shown at the right
appears. Each time this key is
pressed, the currently displayed
value is saved to the clipboard
and the number shown in the symbol is
increased by one.
5 Switch off the DUT before finis-
hing the test with the START/STOP
key.
The Save as symbol appears
(floppy disk icon with the number
of measured values saved to the
clipboard).
6 If you press the save symbol now,
the display is switched to the SAVE
view, where the pre-selected (ME)
device is highlighted.
7 After pressing the Save symbol
once again, acknowledgement of
successful storage appears. At the
same time, the display returns to the

Procedure for measuring with save function and
subsequent entry of the (ME) device
As an alternative to the procedure described
above, you can start with step 4 and, after
measurement has been completed, assign
the results to a (ME) device or its ID number
which is included in the database: manually
by selecting ID and entering the ID via the
alphanumeric keyboard, or by scanning a
barcode.

10 Test Sequences in Accordance
with Standards
If the same sequence of single tests will be
run frequently (one after the other with subsequent report generation), for example as
specified in the standards, it’s advisable to
make use of test sequences. Limit values
have been entered for test sequences in
accordance with standards. And thus a go/
no-go evaluation takes place during measurement based on worst-case assessment.
If the momentary measured value is displayed in green, it lies within the limit values
specified in the standard. If the measured
value is red, is does not fulfill the requirements set forth in the standard. If the measured value is shown in amber, further entries
are required. Even if the DUT fails just a single test step, the test sequence is aborted
and testing in accordance with the selected
standard is failed.
With the help of the SECUTEST DB
COMFORT feature (feature KD01 or
expansion Z853S), test sequences
can be modified such that they’re not
interrupted in the event of a limit value
violation. Amongst other things, this
is helpful for troubleshooting during
repair. Please refer to the operating
instructions for further information.
10.1 General Procedure
1 Select the desired test sequence with
the rotary switch (A1 ... A9).
2 If no test object has been selected, enter
the ID number of the test object, for
example by means of a barcode scanner, after selecting ID.
3 As an alternative to step 2, activate
the database view with the MEM key:
4 Select the test object with the scroll
keys.
5 Return to the measuring view by
pressing the ESC key.
6 Start the test sequence with the
START/STOP key.
7 The measured value recording
symbol shown at the right appears.
Each time this key is pressed, the measuring or evaluation procedure is
restarted (see case B in section 10.2).
8 Proceed to the next measurement by
pressing the key shown to the right.
9 At the end of the test sequence,
you can generate a list of the
results of the individual test steps.
10 If you want to view details such as
the settings for the individual test
steps, select the desired measurement
with the cursor and press the + magnify-
ing glass key.
11 The display is returned to the list of
test steps by pressing the – magnify-
ing glass key.
12 Save the results of a successful test
sequence by pressing the Save key.
10.2 Evaluation Procedure
The evaluation procedure can be started manually for some test steps within a given test
sequence, but all others are run automatically.
• Case A – automatic triggering of evaluation:
Evaluation (with a duration of, for example,
5 seconds) is started automatically as
soon as the measured value has stabilized. The worst value which occurs during
this duration is saved, and automatic
switching to the next test step ensues.
•
Case B – manual triggering of evaluation:
Evaluation is started after pressing
the measurement value recording symbol (display: 0). After a specified period
of time has elapsed, the worst value is
saved to the right of wc: (worst case),
and the number 1 is displayed in the
measurement value recording symbol
indicating that the first measured value
has been saved. Pressing the measured
value recording icon again restarts the
evaluation procedure. If the worst value
is worse that the value obtained for the

the previous worst value, the original
value remains in the display. Depending
on whether you want to delete the last

14 IZYTRONIQ Data Processing
Software
IZYTRONIQ is a database test software that
has been newly developed from scratch. It
enables the user to visualize and manage
the entire testing procedure for all our test
instruments and to document it in an auditproof manner. For the first time, it is thus
possible to combine the test and measurement data from a great variety of test instruments and multimeters in one test and generate one report report thereof. The intuitive
user guidance and modern design provide
for quick access to all functions.
The software is available in different sizes
and versions for trades, industry and vocational training purposes.
Depending on which instrument variant you
order, IZYTRONIQ is included in the scope
of delivery – for example with standard models and instrument sets (see section 2). If this
is not the case or if you would like to take
advantage of a variant with a larger scope of
functions, you can purchase IZYTRONIQ
separately. Detailed information can be
