4.1.1Measurements in IT Systems (new parameter as of firmware
Note
Attention!
!
Note
Note
1.5.0)
The IT system
setting can be
activated for all
single measure-
ments and test sequences in the SETUP switch position (Setup 1/
3) in the All measurements submenu (in this case the symbol
appears in the header of each display page):
With “Measurement at IT system” set to Yes: active leakage current
measurements (or all measurements with reference to PE at the
mains connection side) are disabled. Test sequences which
include measurements of this sort are also disabled.
If, when being connected to line voltage, the SECUTEST detects
a change at PE as compared with the previously used mains connection, the user is asked directly after initial start-up if the currently used outlet belongs to an IT system. The IT system option
in SETUP is activated based on the user’s answer. If “Measurement
at IT system” is activated, this is indicated by the symbol in the
header. Regardless of this, it’s always possible to accordingly
change the option manually in SETUP.
The setting for the “Measurement at IT system” option is retained
even after disconnection from the mains.
Reliable measured values cannot be obtained from active leakage
current measurements (or from any measurements with reference
to PE at the mains connection side) in IT systems, for which reasons all single measurements of this sort, as well as test
sequences which include this type of measurement, are disabled
when the “Measurement at IT system” option has been activated
in SETUP.
Finger Contact
During this test for correct mains connection, a voltage
measurement is performed between the finger contact
and PE at the test instrument’s mains connection, and its
reference potential is acquired via the user’s body resistance to the conductive start key. In order to obtain reliable measurement results, this resistance value must be
less than 1 MΩ. If the user is wearing insulating shoes or
gloves, or is standing on an insulating floor covering,
erroneous measurements and display of the “Interference
voltage at mains connection PE” message may result. Try
to reduce resistance in this case, for example by touching
ground potential with the other hand (e.g. a radiator, but
not an insulating wall etc.).
If, while testing protective conductor potential, you determine that the mains protective conductor is conducting volt-
age (in accordance with the first two cases mentioned),
no further measurements may be performed with the test instrument. If this is the case, potentially dangerous voltage
is also present at the accessible earthing contacts of the
standard socket (test socket). Immediately disconnect
the test instrument from the mains and arrange to have
the fault eliminated at the mains connection.
4.1.2 Automatic Recognition of Mains Connection Errors
The device automatically recognizes mains connection errors if
the conditions in the following table have been fulfilled. The user is
informed of the type of error, and all measuring functions are disabled in the event of danger.

4.2Connecting Test Probe P1 or P2
Insert the double plug from test probe P1 or P2 into socket 1 or 2
respectively such that the plug with the white ring makes contact
with the socket with the vertical bar.
The white ring identifies the terminal for the high current conductor which is safeguarded by the neighboring fuse link.
Difficultly in contacting exposed conductive parts when using
the standard probe with test tip
In order to assure good contact, surface coatings must
be removed from devices under test with special tools at
a suitable location.
The tip of test probe P1 is not suitable for scratching away
paint, because this may impair its coating and/or mechanical strength. Brush probe Z745G may be more suitable than
the test probe in certain individual cases.

5.4.4 Backing Up and Restoring the Database
Any database created in the test instrument (structure and measurement data) can be transmitted to a PC via the USB port and
saved with the help of ETC software.
Alternatively, the database can be saved to a USB flash drive (FAT
formatted, not NTFS) which is plugged in directly to the USB master port at the test instrument (see SETUP 1/3 > Database >
Backup).
During data backup via the USB port (USB connection to
the PC or inserted USB drive), neither the interface cable
nor the USB drive may be disconnected. If the USB drive
is removed during the backup it may be rendered defective.
The test instrument may not be disconnected from supply power during data backup via the USB port.

Restoring the Database – RESTORE
If the database in the test instrument has been inadvertently
deleted, a database version which has been saved to the PC
(ETC) or a USB drive (FAT formatted, not NTFS) can be restored
to the instrument.
Restoring a database from a USB drive is only possible if the
firmware revision level is unchanged. If the firmware has
been updated between backup and restoring, the database is no longer valid and cannot be used.
Data can be restored from an ETC database even after a firmware
update.
5.4.5 Deleting the Database
The database in the test instrument can be deleted in two different ways:
• Press the MEM key > scroll up with the scroll key until the
database is selected > press the DEL softkey.

For direct connection to the test socket (TS)
Devices with single-phase connection,
as well as extension cords via the EL1 adapter
(in which case the EL1 is connected to probe sockets P1)
For permanent connection (to the mains)
By contacting the housing with the probe (for the measure-
ment
of protective conductor resistance or
ing
method for the touch current measurement)

If the test instrument is unable to detect the respective connection
type (e.g. test socket or permanent connection (voltage measuring
inputs)), the suggested connection type must be examined and
the connection type must be specified manually if necessary.
➭ Select parameter settings.
➭ After selecting the measurement type parameter, a list of possi-
ble connection types is displayed.
➭ Select a connection type.
Once a connection type has been selected, it remains active for all
following tests until it’s changed once again.
6.4Manually Selecting a Connection Type /

The test instrument automatically recognizes whether or not the
DUT is connected to the test socket or the voltage measuring inputs
(option). As a default setting, the program sequence assumes
that the plug from the DUT has been connected to the test
socket.
6.1Residual Current Monitoring
For your safety, the test instrument is equipped with continuous
residual current monitoring. If residual current exceeds a specified
limit value, all measuring processes are stopped, and if line voltage is fed through the test socket it’s disconnected. This limit
value can be set to one of two levels in the SETUP switch position:
Setup 1/3 > All Measurements > Residual Current Protection >
10 mA
/30 mA
6.2Specifying Reference Voltage L-PE
The reference (line) voltage is the voltage to which the measured
values for leakage current have been standardized. It’s used to
mathematically calculate leakage current and not for specifying
target line voltage.
Reference voltage can be adjusted in setup:

Protection Class II Devices with Protection Class I Mains Plugs
If the device under test is equipped with a protection
class I plug although it complies with protection class II,
protection class I is recognized by the test instrument. If
this is the case, switch the protection class parameter
from I to II.
Testing Several Protective Conductor Connections with the Function for “Automatic Detection of Measuring Point Changes”
During protective conductor measurement, the test instrument
recognizes whether or not test probe P1 is in contact with the
protective conductor, which is indicated by means of two different
acoustic signals.
This function can be adjusted in the SETUP switch position in the
“Auto Measurements” submenu via the “Auto Measuring Point”
parameter.
Protective Conductor and Insulation Resistance Measurements for
Permanently Installed Devices Under Test
Deactivate the electrical system which supplies power to
the device under test before connecting the test instrument!
➭ Remove the mains fuses from the device under test and dis-
connect neutral conductor N inside the device under test.
Touch Current Measurement (absence of voltage)
Make sure that the contacted parts are not grounded.
6.8Connection Tests Conducted by the Test Instrument
The following measurements are performed automatically when
the DUT is connected to the test instrument.
• Connection test (detection of connection via either the test
socket or the voltage measuring inputs) (only with countryspecific earthing contact version)
• Protection class detection (with earthing contact connection
only: detection of whether or not the protective conductor is
connected)
•Short-Circuit Test
•
On test
(test of whether the device under test is switched on or off)
• Probe test (detection of whether or not test probe P1 is
plugged in)
• Electronic fuse (test of whether or not the fuse in the DUT is
tripped at a residual current of > 10 mA)
• Measurement of starting current (if starting current is greater than
16 A after 200 ms, the following message appears: “Use an
external adapter or another measuring method”)

6.62nd Test Probe (only SECUTEST PRO or feature H01)
If the device under test is not equipped with a country-specific
mains plug which fits into the test socket at the SECUTEST, or if a
permanently installed DUT is involved, the second test probe, in
combination with the first test probe, permits 2-pole measurement (dual-lead-measurement) of RPE, RISO and equivalent leakage current.
Measurements with test probe 1 against test probe 2 (P1 – P2)
are electrically isolated from the mains. There’s no voltage at the
test socket.
Please note that during insulation measurement the
maximum test voltage of 500 V may be applied between
the probes.
6.7Connection Prompts
Depending on which single measurement is selected (green rotary
switch position), and depending on DUT or adapter connection,
prompts appear regarding connection of the probes, and regarding connection of measurement cables to the voltage measuring
inputs in the case of the SECUTEST PRO.

7Notes on Saving Single Measurements and Test
Sequences
At the end of each test, test results can be saved under an ID
number which is unequivocally assigned to the respective DUT.
Depending on the initial situation, i.e. whether or not a test structure or database is already available or an ID has already been
entered, the following different procedures are used for saving:
Variant 1 – pre-selection of an existing ID
You’ve already set up a test structure in the test instrument or
uploaded one with the help of ETC report generating software.
Open the database view before starting the measurement by
pressing the MEM key. Then select the device under test or its ID
within the test structure by pressing the respective scroll key. Exit
the database view (MEM navigation) by pressing MEM and start the
measurement. Press the “Save as” key at the end of the measurement. The display is switched to the SAVE view. The ID
appears with a green or orange background. Press the save
key once again in order to complete the procedure.
Variant 2 – entry of an existing ID at the end of the test
You’ve already set up a test structure in the test instrument or
uploaded one with the help of ETC report generating software.
You perform the measurement without first opening the database.
No device under test was previously selected in the database.
Press the “Save as” key at the end of the measurement. The
following message appears: “No DUT selected!” Press the ID key.
The softkey keyboard appears.
If you enter an ID here which is already in the database, the database view appears (MEM navigation) automatically, and the DUT’s
ID is displayed inversely. Acknowledge the entry by pressing the
key. The display is switched to the SAVE view. The ID appears
with a green or orange background. Press the Save key once
again in order to complete the procedure.
Variant 3 – entry of a new ID at the end of the test
You haven’t yet set up a test structure in the test instrument, or
the ID is not included in the existing structure.
Press the “Save as” key at the end of the measurement. The
following message appears: “No DUT selected!” Press the ID key
in order to enter the DUT’s ID. The softkey keyboard appears.
If you enter an ID here which is not yet included in the database, a
prompt appears asking you if you want to enter a new object.
– : If you press , the display is switched to the SAVE view. The
ID appears with a green or orange background. Press the save
key once again in order to complete the procedure.

Special Case: Testing Protective Conductor Resistance at PRCDs
Note
(as of firmware V1.4.0)
For PRCDs whose protective conductor resistance cannot be
measured when switched off, the SECUTEST BASE(10) offers the
“active: PE(TS) - P1” measurement type, with which the PRCD
can be switched on in order to ascertain protective conductor
resistance.
➭ Set the measurement type parameter to “active: PE(TS)
–
P1”.
➭ Connect the EL1 adapter (or alternatively a normal test probe)
to the P1 sockets at the test instrument.
➭ Connect the plug of the PRCD under test to the test socket.
➭ Connect the EL1 adapter to the outlet on the PRCD (alterna-
tive: connect the test probe to the protective conductor of the
PRCD’s outlet, e.g. by means of an alligator clip).
➭ Start the measurement.
➭ Switch line voltage to the test socket. Then switch the PRCD
on.
➭ Otherwise, the test sequence is the same as described
above.
With the +200 mA=, –200 mA= and ±200 mA= measurement types, test current rises very slowly in order to
prevent triggering of residual current monitoring at the
PRCD. And thus with this measurement type, it may take
longer than usual until a valid measured value is displayed. For this reason, the protective conductor should
not be contacted manually with the test probe, in order to
prevent a sudden rise in test current resulting in inadvertent tripping of the PRCD.

Prerequisite for Testing
The measurement of insulation resistance may not be
conducted on protection class I devices which have not
passed the protective conductor resistance test.
The insulation test cannot be performed for all DUTs, for
example electronic devices, EDP equipment etc. Leakage current measurements must be performed for these
DUTs (see Section 8.7).
Observe the notes in the service instructions.
Touching the DUT During Measurement
Testing is conducted with up to 500 V, and although current is limited (I < 3.5 mA), if the DUT is touched electrical
shock may occur which could result in consequential accidents.
Switch Settings at the DUT
All switches at the DUT must be set to the on position
during measurement of insulation resistance, including
temperature controlled switches and temperature regulators as well.
Measurement must be performed in all program steps
for devices equipped with program controllers.

Selection of
polarity for mains voltage
The device under test can be subjected to a function test with
mains voltage via the integrated test socket.
The test socket is tested for short-circuiting before switching to
line voltage (a statement resulting from the short-circuit test can
only be made regarding the DUT itself when a single-phase DUT
is being tested).
In addition to testing with the selector switch in the function test
position, a function test can also be performed immediately after
safety testing has been passed in accordance with the selected
standard (not possible for protection class III devices).
Test Sequence
The function test may only be performed after the DUT
has successfully passed the safety test.
Refer to the safety precautions on page 6 with regard to
switching power consumers.

• CEE adapter (only for connection via
single-phase CEE or “caravan socket”)
• AT3 adapter (AT3-IIIE, AT3-IIS, AT3-IIS32)
• AT16DI/AT32DI
Starting the Function Test
For reasons of safety, the device under test must be
switched off before the function test is started. This precaution prevents inadvertent start-up of a DUT which
may represent a hazard during operation, e.g. a circular
saw or a disc grinder.
Ending the Function Test
After completion of the function test, DUTs must be
turned off with their own switch – especially devices with
relatively high inductivity.
➭ Set the rotary switch to the P position.
➭ Connect the DUT’s mains plug to the test instrument’s test

AUTO
* Assuming the respective sequence parameter is preset to “on”
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 (also called measuring sequences).
Limit values have been entered for test sequences in accordance
with the 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 orange, further entries are required after the
test step (e.g. cable length), which are decisive as to whether or
not the test has been passed. Even if the DUT fails just one single
measurement, the test sequence is aborted and testing in accordance with the selected standard is failed.
Automatic test sequences are run in rotary switch positions
AUTO, as well as A1 through A8.
Test sequences A1 to A8 and AUTO are preconfigured at the factory.
We recommend assigning frequently used test sequences to A1
through A8, and conducting special sequences for which parameters often need to be adjusted in the AUTO switch position.
The measurements are evaluated automatically by the test instrument. Evaluation is based on the worst-case and, depending on
settings, in consideration of measuring uncertainty.
Test Sequences in Switch Positions A1 to A8 (option)
Up to 8 customer-specific test sequences can be assigned to
these rotary switch positions. The sequences are created at the
PC with the help of Sequence Designer software. Possible
sequence parameters are downloaded from the test instrument to
the PC program and dynamically adapted. The test sequence is
finally uploaded to the SECUTEST PRO as an XML file.
The sequence is tested for errors and plausibility at the PC – not
at the test instrument.
Specifications for the test sequences can be entered to the test
instrument in two different ways:
• SETUP switch position: general settings can be entered which
apply to all test sequences (regardless of the respectively
selected standard).
• Switch positions AUTO and A1 through A8: classification and
sequence parameters can be entered which only apply to the
selected switch position.
Sequence Designer
With the help of Sequence Designer software, test sequences can
be created at the PC and transferred to the test instrument via a
USB connection or a USB flash drive.
Test Sequences in the AUTO Switch Position
The following test sequences are included as a standard feature
with the SECUTEST BASE(10) in the AUTO switch position:
• DIN VDE 0701-0702
Recurrent test and test after repair and modification of electrical equipment
• IEC 62353
Medical electrical equipment – Recurrent test and test after
repair of medical electrical equipment (applied parts with test
probe P1)
• IEC 60974-4
Arc welding equipment – Part 4: Periodic inspection and testing (voltage measurement with test probe P1 without electrical
isolation). One pole of the voltage to be measured must be
connected to PE at the mains.
The individual sequences are selected with the softkeys.
GMC-I Messtechnik GmbH51
If you change or shorten the default test sequences for
the respective standards, the danger exists that they will
no longer be compliant and will thus become invalid as
substantiation of operating safety in accordance with
DGUV regulation 3 or BetrSichV, or will no longer fulfil
these standards.

❑ Considering Measuring Uncertainty
If Yes is selected, measuring uncertainty is taken into consideration when the measurement results are displayed. The final
result which appears at the display is downgraded by an
amount equal to measuring uncertainty.
❑ Auto Measuring Point
If Yes is selected, the test instrument detects whether or not
the protective conductor is contacted with the probe during
the protective conductor resistance measurement and automatically starts recording a new measuring point. Statuses are
indicated by various, continuous acoustic signals. The protective conductor test can thus be conducted without using the
keys on the instrument.

Selection can be made here between a tree view and a detail
view for the first page of the test sequence (see section 10.2).
❑ Limit Value Mode
If you want to use the limit values specified in the standards to
evaluate the measurements, set the parameter to Normal.
When set to Expert, the LIMIT softkey appears next to the
“measurement failed” popup if the measurement has not been
passed. This key makes it possible to enter a user-defined
limit value (as a rule a limit value specified by the manufacturer
which deviates from the standard), in order to allow the test to
be passed under these new conditions.

Mains Connection Errors
– Protective conductor PE at the
mains outlet at which the SECUTEST is being operated is conducting voltage! This detection function
makes use of the metallized
START/STOP key on the test
instrument. In order for detection to
function correctly, it must be possible to establish reference to earth
potential via the user’s finger.
If the user’s finger is insulated
from the key when it’s
pressed, this error message
may occur although the installation is OK (see “Automatic
Recognition of Mains Connection Errors” on page 9).
PE connection not detected (at the
outlet at which the test instrument is
being operated):
– If the installation is defective!
– In the case of special types of TT
systems; detection may fail in this
case.
– If the test instrument is being oper-
ated in an IT system
As opposed to the previously used
mains connection, PE was detected
while the IT system option was activated in setup.
➭ Please remove the SECUTEST’s
mains plug from this outlet and arrange to have the outlet/installation inspected by a qualified
electrician without delay. Do not
operate any other devices at this
electrical outlet before this inspection has been completed.
➭ In order to ensure that detection
functions reliably, repeat the interference voltage test and observe
the following tips:
– Unplug all USB devices from the
SECUTEST’s USB ports.
– Remain in contact with a
grounded object while pressing
the START/STOP key (e.g. a
heating pipe).
– Do not contact the START/STOP
key with an object or while wearing
gloves.
➭ If the test instrument is being oper-
ated in an IT system:
Acknowledge the question by
pressing – the IT system option
is activated in this case.
➭ If it’s not an IT system: remove the
mains plug from the outlet and inspect the installation without delay!
➭ If it’s a TT system without neutral
conductor, press ; direct leakage current measurements are
possible.

13.1Housing Maintenance
No special maintenance is required for the housing. Keep outside
surfaces clean. Use a slightly dampened cloth for cleaning. Avoid
the use of cleansers, abrasives or solvents.
13.2Testing the Color Display and the Buzzer
(self-test parameter)
The color display can be tested for failure of individual segments
and loss of color components on page 3/3 of the setup menu in
the SETUP switch position under the self-test parameter.
Beyond this, the buzzer can be tested for 3 different frequencies.
13.3Software Update (system info parameter)
The current firmware or software version can be queried via the
system info parameter (setup 3/3).
The test instrument’s firmware can be updated via the USB port
with the help of a PC. Updating is only possible via the proprietary

Before updating the firmware, it is imperative that you
save the structures you have created and your measuring data as they might be deleted in the process, see
section 5.4.4, “Backing Up and Restoring the Database”.
” application, which is integrated into the firm-
13.6Recalibration
The measuring tasks performed with your instrument, and the
stressing it’s subjected to, influence aging of its components and
may result in deviation from the specified levels of accuracy.
In the case of strict measuring accuracy requirements, as well as
in the event of use at construction sites with frequent stress due
to transport and considerable temperature fluctuation, we recommend a relatively short calibration interval of once per year. If your
instrument is used primarily in the laboratory and indoors without
considerable climatic or mechanical stressing, a calibration interval of once every 2 to 3 years is sufficient as a rule.
During recalibration* at an accredited calibration laboratory
(DIN EN ISO/IEC 17025), deviations from traceable standards
demonstrated by your measuring instrument are documented.
Ascertained deviations are used to correct display values during
later use of the instrument.
We would be happy to perform DAkkS or factory calibration for
you at our calibration laboratory. Further information is available at
our website:
www.gossenmetrawatt.com (→ Company → DAkkS Calibration
Center or → FAQs → Questions and Answers Regarding Calibration).
According to DIN VDE 0701-0702, only test instruments which
are tested and calibrated at regular intervals may be used for testing.
Recalibration of your instrument at regular intervals is essential for
the fulfillment of requirements according to quality management
systems per DIN EN ISO 9001.
Adjustment data are not overwritten during updating.
Recalibration is therefore not necessary.
The most up-to-date version of the software (firmware) can be

13.4Backup Battery for Real-Time Clock
The backup battery (lithium cell) should be replaced no later than
after 8 years. Replacement can only be executed by the service
department.
If backup battery voltage is too low, the date and time assigned to
the test data no longer correspond to the actual time of recording.
This may also influence sorting in ETC report generating software.
The instrument’s database itself is not affected by a depleted
backup battery.
13.5Fuse Replacement
The fuses may only be replaced when the instrument is voltagefree, 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.
* Examination of the specification, as well as adjustment, are not included
in calibration. However, in the case of our own products, any required
adjustment is performed and adherence to the specification is confirmed.
13.7Technical Safety Inspections
Subject your test instrument to technical safety inspections at
regular intervals. We recommend the same interval for inspections
as is also used for recalibration.
The SECUTEST... is designed as a totally insulated device in
accordance with IEC 61010 and VDE 0404. The protective conductor is used for measuring purposes only, and is thus not
always accessible. The protective conductor at the test socket
can be tested as follows:
For technical reasons, insulation resistance between LN and PE
inside the SECUTEST... is roughly 3 MΩ.
This must be taken into consideration during technical safety
inspections or, instead of the insulation resistance measurement,
the protective conductor current measurement must result in a
value of less than 3.5 mA (or less than 7 mA if the equivalent leakage current method is used).
There are also 4 accessible conductive parts on the SECUTEST..., at which the touch current measurement must result in a
value of less than 0.5 mA:
• Connector for service plug (jack socket)
•USB ports
• Metallized start key
• Protective conductor bar in the test socket
In order to prevent damage to the SECUTEST... test
instrument, we recommend avoiding the performance of
measurements at the USB ports.
