2 Safety Features and Precautions
The test instrument fulfills all requirements of applicable EU direc-
tives and national regulations. We confirm this with the CE mark.
The relevant declaration of conformity can be obtained from
GMC-I Messtechnik GmbH.
The test instruments are manufactured and tested in accordance
with the following safety regulations: IEC 61010-1 / DIN EN
61010-1 / VDE 0411-1,
DIN EN 61557-16/VDE 0413-16 .
Safety of the operator, as well as that of the test instrument and
the device under test, is only assured when it’s used for its
intended purpose.
Read the operating instructions carefully and completely before placing your
test instrument into service. Follow all instructions contained therein. Make
sure that the operating instructions are available to all users of the instru-
ment.
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 eval-
uation of the test.
Suitable personal safety equipment is required.
If you use active or passive body assistance, please consult with
your physician or the manufacturer of the body assistance device.
Note
Manufacturers and importers of medical electrical equipment
must provide documentation for the performance of mainte-
nance by trained personnel.
Observe the following safety precautions:
• The instrument may only be connected to TN, TT or IT electrical sys-
tems with a maximum of 240 V which comply with applicable safety
regulations (e.g. IEC 60346, VDE 0100) and are 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 condi-
tion, 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 if it has been
inserted into a jack socket. Tensioning at the coil cord may
otherwise cause the test probe to snap back resulting in pos-
sible injury.
•Measurement of insulation resistance and equivalent leakage current
(alternative leakage current measuring method)
Testing is conducted with up to 500 V. Current limiting is uti-
lized (I < 3.5 mA), but if terminals L or N at the test socket or
the test probe are touched, electrical shock may occur which
could result in consequential accidents.
•Leakage current measurement while connected to line voltage
It’s absolutely essential to assure that the device under test is
operated with line voltage during performance of the leakage
current measurement. Exposed conductive parts may con-
duct dangerous touch voltage during testing, and may not
under any circumstances be touched.
(Mains power is discon-
nected if leakage current exceeds approx. 10 mA.)
Attention!
!
The function test may only be performed after the DUT has
successfully passed the safety test!
•Probe test probe connection P1
Test the probe after completing each test (see also section
10.2.2).
Attention!
!
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!
•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.
Connecting Line Voltage
Connecting line voltage to the test socket at the test instrument
and performance of a function test are only permissible if the DUT
has already passed all safety test steps! Depending on the DUT’s
protection class, this means that visual inspection, as well as
measurement of protective conductor resistance and insulation
resistance, must have been passed.
Do not start measurements at your test instrument unless the test
instrument and the DUT are in plain view. Do not connect line
voltage to the test socket of your test instrument before the sur-
rounding area has been secured. This applies to individual mea-
surements as well as to test sequences, and in particular to
remote operation via the remote control interface.
Switching Power Consumers – 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.
2Test 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.
5Test instrument: Deactivate line voltage to the test socket.
Switching Loads – Maximum Starting Current
The test instrument permits active testing of devices with a nomi-
nal 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.
Attention!
!
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:
“L(N) test socket fuse defective”.
➭Check both of the mains connection’s fuse links. If they’re 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 instru-
ment 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.

8GMC-I Messtechnik GmbH
2.1 Test Instructions for Applied Parts Measuring Functions
The test instrument itself should be tested at regular intervals in
order to assure the correctness of measurements and tests. This
is possible by performing just a few measurements with a multi-
meter and the SECU-cal 10 calibration adapter. This applies in
particular to measurements at the APP sockets because possible
defects in the APP sockets’ multiplexer are difficult to detect.

4 Initial Startup
4.1 Connecting the Test Instrument to the Mains
➭See section 12 for nominal mains values (nominal ranges of
use).
➭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) isn’t 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.
Attention!
!
If connection isn’t 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 dia-
gram.
Disconnection from mains power is only possible via the
mains plug.
Figure 1 Connecting the Test Instrument to the Mains
4.1.1 Measurements in IT Systems (new parameter as of firmware
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 icon
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 test instrument
detects a change at PE as compared with the previously used
mains connection, the inspector is asked directly after initial start-
up if the currently used outlet belongs to an IT system. The IT sys-
tem option in SETUP is activated based on the user’s answer. If
“Measurement at IT system” is activated, this is indicated by the
icon 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.
In IT systems, active leakage current measurements (or any mea-
surements with reference to PE at the mains connection side) do
not deliver reliable measured values, for which reason all single
measurements of this sort, as well as test sequences which
include this type of measurement, are disabled when the “Mea-
surement at IT mains” option has been activated in SETUP.
The Meas. at IT mains parameter can be set in Setup:

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 dis-
abled in the event of danger.
110/25 A RPE measurements are only possible with line voltages of 115/
230 V and line frequencies of 50/60 Hz.
2
If the user of the test instrument is too well insulated, the following error mes-
sage may appear:
“Interference voltage at mains connection PE”
Note
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 resis-
tance to the conductive start key. In order to obtain reli-
able 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.).
Attention!
!
If, while testing protective conductor potential, you deter-
mine that the mains protective conductor is conducting volt-
age (in accordance with the first two mentioned cases),
no further measurements may be performed with the test in-
strument. 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.
Note
Voltage at the electrical system’s protective conductor PE may
result in distorted measurement values during testing for
the absence of voltage, or during leakage voltage mea-
surements.
4.2 Connecting 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 conduc-
tor which is safeguarded by the neighboring fuse link.
Note
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 isn’t suitable for scratching away
paint, because this may impair its coating and/or mechani-
cal strength. Brush probe Z745G may be more suitable than
the test probe in certain individual cases.

See section 13.3 regarding downloading the latest software version.
Notes Concerning the Inspector Parameter
– The inspector who has just been “selected” appears in com-
pleted tests as the “Inspector”. None of the test instrument’s
settings are stored specifically for the inspector – all of the set-
tings at the test instrument are stored for the respective
device and are available to all inspectors.
–
If an inspector is password-protected , this only prevents users who don’t
know the password from “selecting” this inspector. There’s
no pass-
word prompt when the test instrument is started up.
The inspector
remains selected even in the event of a power failure – a
(password-protected) inspector can only be unselected by
selecting another inspector.
In order to delete an inspector whose password you don’t
know, it’s sufficient to enter an incorrect password five times
in a row and to confirm the entry each time – a query then
appears as to whether or not the inspector should be deleted.
The inspector to be deleted may not be the same as the cur-
rently selected inspector.

5 Internal Database
5.1 Creating Test Structures, General
A complete test structure with data regarding customer proper-
ties, buildings, floors, rooms and test objects can be created in
the test instrument. This structure makes it possible to save the
results of single measurements or test sequences to test objects
belonging to various customers. Manual single measurements
can be grouped together into a so-called “manual sequence”.
Objects can be identified with the following parameters (boldface
parameters are mandatory entry fields):
• Device ( ID , designation, location, test interval *, type, manufac-
turer, comment, serial number, protection class, cost center
* ,
department
* )
• ME equipment ** ( ID , designation, customer , test interval *, type, manu-
facturer, comment, serial number, protection class, number of type B
applied parts **,
number of type BF applied parts **, number of type CF ** applied
parts, cost center, department, UDI **, mains connection **)
•Room * (ID and designation)
•Floor * (ID and designation)
•Building * (ID, designation, street, ZIP code and city)
•Property * (ID and designation)
•Customer (ID, designation, street, ZIP code and city)
Key
ID = identification number
5.2 Transmitting and Saving Test Structures and Measurement
Data
The following functions are possible (as far as the test instrument
is concerned):
•Export: Transfer a structure including measured values from
the test instrument to the PC (ETC *** or IZYTRONIQ) (see sec-
tion 5.2.1).
•Import *: Transfer a test structure from the PC (IZYTRONIQ) to
the test instrument (see section 5.2.2).
•Backup *: Back up a database to a USB flash drive plugged
into the test instrument (must be FAT32 formatted – not NTFS)
(see section 5.2.3).
•Restore *: Restore a database to the test instrument from a
USB flash drive plugged into the test instrument (must be
FAT32 formatted – not NTFS) (see section 5.2.3).
•Reports: Save reports to a USB flash drive (see section 3.5.6).
If no USB flash drive has been plugged in, the above listed func-
tions are grayed out and disabled.
In order to transfer structures and data, the test instrument and
the PC must be connected with a USB cable or a USB flash drive
must be available.
Please observe the following safety precautions:
Attention!
!
During data transmission via the USB port (USB connec-
tion to the PC or connection of a USB flash drive), neither
the interface cable nor the USB drive may be discon-
nected.
Attention!
!
The test instrument may not be disconnected from sup-
ply power during transmission via the USB port. The
memory structure in the test instrument might otherwise
be destroyed.
Note
Data transfer to the PC should not be started during sin-
gle measurements or test sequences.
5.2.1 Export – Transmitting Test Structures and Measurement
Data from the Test Instrument to the PC
Structures set up in, and measurement data saved to the test
instrument can be exported to IZYTRONIQ report generating soft-
ware via a connected USB flash drive (only with data base exten-
sion or feature KB01, “Z853R – SECUTEST DB+”), or via the USB
slave port. Select Export IZY file under Setup > Database 2/2 to
this end. The data are converted to an IZYTRONIQ-compatible for-
mat with the “.secu” file extension.
The report generating program is started at the PC by double
clicking the exported file and the data are read in. Data can then
be saved to the PC and reports can be generated.
5.2.2 Import – Uploading Test Structures Created in the Report Gen-
erating Program to the Test Instrument (only with database
extension or feature KB01, “Z853R – SECUTEST DB+”)
As an alternative, a test structure can be created at the PC with
the help of the report generating program and then transferred to
the test instrument via a connected USB flash drive, or via the
USB slave port. Select the Import IZY file function to this end under
Setup > Database 2/2. The data are converted to a format which
is compatible with the test instrument.
A complete description of database creation can be found in the
online help included with the report generating program.
The same backup files apply here as is also the case in the sec-
tion covering export.
5.2.3 Backing Up and Restoring Test Structures and Measure-
ment Data
Structures created and measurement data saved at the test
instrument can be backed up via an inserted USB flash drive
(must be FAT32 formatted – not NTFS). Select the Backup function
to this end under Setup > Database 2/2.
The test instrument creates a backup file on the USB flash drive
directly in the root directory.
The backup files on the USB flash drive are named by means of a
time stamp (file extension: .etcbak).
In order to restore structures and data from an inserted USB flash
drive, select the Restore function under Setup > Database 2/2.
When restoring, the files from the root directory are displayed as
well as those from the backup folder (which used to be created in
previous firmware versions). The files from the backup folder are
displayed with the “>” prefix.
Note
Backup/Restore to/from USB Flash Drive
It’s also possible to restore backup files created with previ-
ous firmware versions.
Attention!
!
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 defec-
tive.
Attention!
!
The test instrument may not be disconnected from sup-
ply power during data backup via the USB port.

cal equipment.
Note
Mandatory Entries
Mandatory entries are identified in red in the entry fields at
the test instrument as well as in the illustrations in Figure
4 and Figure 5.
Note
Hierarchies
The following hierarchies must be complied with:
Room or Floor must always be subordinate to Building.
Devices or ME equipment (medical electrical equipment)
must always be allocated to a Customer.
Hierarchies and Data Migration
Database objects “Device” and “ME equipment” must always be
subordinate to a Customer. If so-called “legacy data” have been
imported into the test instrument which do not comply with this
rule (e.g. as a result of a firmware update or via the “Restore data-
base” function), Customer objects are generated automatically.
The same applies to database objects “Room” and “Floor”, which
must always be subordinate to a Building. In this case, Building
objects are generated automatically if necessary.
