2 Safety Features and Precautions

Note
Attention!
!
Attention!
!
!
SECUTEST BASE(10) and SECUTEST PRO test instruments fulfill all
requirements of applicable European and national EC directives. 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 VDE 0404, 4, DIN EN 61557-16/VDE 0413-16 (draft).
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 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 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.
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 TN, TT or IT electrical
systems 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
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 leakage current measuring method)
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.
Leakage current measurement while connected to line voltage
It is 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 con­duct dangerous touch voltage during testing, and may not under any circumstances be touched. nected if leakage current exceeds approx. 10 mA.)
DIN VDE 0413 parts 2 and

4)
5) Tes te r:
Switch line voltage to the test socket.
DUT: Turn the DUT on via its own switch.
DUT: Turn the DUT off via its own switch.
Deactivate 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 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 an unauthorized/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 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
The function test may only be performed after the DUT has successfully passed the safety test!

4 Initial Start-Up

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) 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.
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.

3.7 Writing RFID Tags (as of firmware V1.5.0 with option for database expansion)

The following function is made possible by an RFID scanner (writer):
• Read-out of encrypted ID numbers for devices under test to
an RFID tag for quick and convenient read-in during periodic testing
If you have connected a suitable RFID scanner (see list in appen­dix in section 14.1) via the USB master port, you can write an RFID tag for each device under test by pressing the PRINT key:

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.

4.2 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 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.

5.1 Creating Test Structures, General

A complete test structure with data regarding customer buildings, floors, rooms and devices under test can be created in the test instrument. This structure makes it possible to assign single mea­surements or test sequences to devices under test 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:
DUT (ID
, designation, type, manufacturer, serial number, com-
ment, cost center
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)
*Only with SECUTEST PRO and with SECUTEST DB+ option (Z853R database
expansion or feature KB01)
*
, department*)
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) (see section 5.2.1).
Import: Transfer a distributor structure from the PC (ETC) to the
test instrument (SECUTEST PRO only) (see section 5.2.2).
Backup: Backup a database to a USB flash drive (FAT format-
ted, not NTFS) plugged into the test instrument (see section
5.2.3).
Restore: Restore a database to the test instrument from a USB
flash drive (FAT formatted, not NTFS) plugged into the test instrument (see section 5.2.3).
Reports: Save reports to a USB flash drive (see section 3.8).
If no USB flash drive has been plugged in, the above listed func­tions are displayed in gray and are 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:
During data transmission via the USB port (USB connec­tion to the PC or connection of a USB drive), neither the interface cable nor the USB drive may be disconnected.

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 ETC report generating software via a connected USB flash drive (only with SECUTEST PRO or instru­ments with feature KB01), or via the USB slave port. Select Export ETC file under Setup > Database 2/2 to this end. The data are converted to an ETC-compatible format with the “etc” file exten­sion. ETC 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.
The most up-to-date version of ETC report generating software can be downloaded free of charge from the mygmc page of our website as a ZIP file, if you have registered your test instrument:

5.2.2 Import – Uploading Test Structures Created in ETC to the Test Instrument (only with SECUTEST PRO or instruments with feature KB01)

As an alternative, a test structure can be created at the PC with the help of ETC software and then transferred to the test instru­ment via a connected USB flash drive or via the USB slave port. Select the Import ETC file function to this end under Setup > Data­base 2/2. The ETC 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 ETC software.
The same safety precautions apply here as was also the case in the section covering export.

5.2.3 Backing Up and Restoring Test Structures and Measurement Data

Structures created and measurement data saved at the test instrument can be backed up via an inserted USB flash drive (FAT formatted, not NTFS). Select the Backup function to this end under Setup > Database 2/2. The test instrument creates a DATABASE directory at the USB flash drive (if it doesn’t already exist) and generates a backup file.
If there’s already a backup file in this directory, you’re asked if it should be overwritten. A new backup with the same name is only create if you respond to the prompt in the affirmative with the icon.
In order to restore structures and data from an inserted USB flash drive, select the restore function under Setup > Database 2/2. The test instrument accesses the backup file automatically.
Backup/Restore to/from USB Flash Drive
Backups can only be restored within the same firmware revision level. If the firmware has been updated between
The test instrument may not be disconnected from sup­ply power during transmission via the USB port. The memory structure in the test instrument might otherwise be destroyed.

There are three ways to enter search terms: – Via the softkeys – Via a connected USB keyboard – Via barcode or RFID scanner
The keyboard entry function is opened automatically in any case.
The search is started after the entered search term has been
acknowledged.
Only exact matches are displayed: no wildcards, case sensitive.
The found object is displayed inversely. The designation and ID number can be shown or hidden by
pressing the magnifying glass symbol.
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:

VL2E adapter

6.3 Manually Specifying the Connection Type for Single Measurements

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.

6.4 Manually Selecting a Connection Type / Protection Class for Automatic Test Sequences

If the test instrument is unable to detect the respective connection type or protection class, the suggested connection type must be examined and the connection type or protection class must be specified manually if necessary.

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.

6.1 Residual 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

6.2 Specifying 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: Setup 1/3 > All Measurements > Ref. Voltage L-PE

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.

6.7 Connection 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.
A list of possible DUT connections depending on type of mea­surement is included in section 11.2.

7 Notes 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.
: If you press , the database view appears (MEM naviga-
tion). Go to the next page (Edit objects 2/3) by pressing , and then enter a new object. Press to this end. All possible object types are displayed. Press “DUT”. The newly entered ID appears in red to the right of the ID parameter. Acknowledge the entry by pressing the key. The display is switched to the database view (MEM navigation). The newly entered device under test is displayed inversely in the structure. Press MEM in order to return to the SAVE view. The ID appears with a green background. Press the save key once again in order to com­plete the procedure.
ESC: If you don’t want to save any measured values, press ESC
twice in order to go to the measuring view. If you press ESC again, a prompt appears asking whether or not you want to delete the measuring points in order to continue with the mea­surement without saving.

8.1 General

The desired measurement is selected with the help of the green pointer on the rotary switch and the green semicircle.
• The respective measurement is configured with the help of the softkeys. The parameter settings can be accessed by pressing the softkey with the symbol shown at the right.
•The measurement type parameter displayed in each case in the footer can be changed directly using the key shown at the right without having to exit the measuring view.
• The selection of can be changed directly using the key shown at the right without having to exit the measuring view.
• No limit values can be specified for single measurements, and thus there is no evaluation.

for line voltage at the test socket
• Checking is performed before each measurement in order to assure a trouble-free sequence, and to prevent any damage to the DUT.
• Single measurements can be saved to memory. The assignment of an ID number is possible to this end.
• Single measurements can be combined into measurement series.
• Mains power can be connected to the DUT with the desired polarity by making a pre-selection in the parameter settings.

8.3 Displaying the Last Measured values

1 Start the measurement by pressing the START/STOP key.
The symbol shown at the right appears and indicates how many measurements have already been per­formed.
2 Stop the measurement by pressing the START/STOP
key, unless a specified measuring time has been stipu­lated. The save symbol (floppy disk with a number 1) appears and indicates that one valid measured value has been recorded, which can now be saved.
3 Press the save icon (floppy disk).
“No DUT selected!” appears.
4 In order to view the last measured values, press the
symbol for executed measurements after testing. The last measured values are displayed.
5 The desired measurement can be selected with the
scroll keys.
6 The associated measuring parameters can be shown or
hidden using the keys shown at the right.
7 The measured value view is exited by pressing the
green checkmark, in order to subsequently save the mea­sured values (as described in Section 8.4) or to return to the initial view by pressing the ESC key.

8.4 Measurement Series and Storage

Single measurements can be combined into measurement series. The measured values can be saved by pressing the save key, or measurement series can be generated. These can be saved to a DUT (ID number) which has already been set up in the database (see Section 5.4.1). The appearance of the save key changes depending on meaning.
Measuring Sequence with Pre-Selection of the DUT
1 Activate the database view (MEM navigation) by pressing the
MEM key.
2 Select the DUT or its ID number for the following measure-
ments with the scroll keys.
3 Return to the measuring view by pressing the MEM key or
the START/STOP key.
4 Start the test with the START/STOP key.
The symbol shown at the right appears and the zero indicates that no measurements have yet been recorded or saved to buffer memory.
5 Each time the key at the right is pressed, the respec-
tively current measured value is saved to buffer mem­ory and the number shown in the symbol is increased. In this way, you always know how many measurements have already been recorded.
6 Stop the measurement by pressing the START/STOP
key, unless a specified measuring time has been stipu­lated. The save as symbol appears (floppy disk icon with the number of measured values saved to the clipboard).
7 If you press the save symbol now (floppy disk), the dis-
play is switched to the DUT in the database view for checking.
8 After pressing the save symbol once again, acknowledgement
of successful storage appears. At the same time, the display is switched to the measuring view.
Measuring Sequence with Subsequent Entry of the DUT
1 Start the measurement by pressing the START/STOP key.
The symbol shown at the right appears and indicates how many measurements have already been per­formed.
2 Stop the measurement by pressing the START/STOP
key, unless a specified measuring time has been stip­ulated. The save symbol (floppy disk with a number 1) appears and indicates that one valid measured value has
been recorded, which can now be saved. 3 Press the save symbol (floppy disk). 4 You are informed that you haven’t selected a DUT in
the database. 5 There are two ways to subsequently select a DUT
using an ID number which has already been set up in
the database:
– Select the ID number with a barcode scanner
or
– Enter an ID number by pressing the ID key. 6 The cursor jumps to the location of the DUT with the selected
ID number. You only need to acknowledge this position by
pressing the green checkmark. 7 Press the save symbol (floppy disk).
A message appears indicating that the data have been suc-
cessfully saved and the display is switched to the measuring
view.
If the entered number cannot be found in the database (because it hasn’t been set up), it can be entered imme­diately by pressing Yes when the prompt appears. However, the storage location cannot be selected in this case. The measurement is saved to the most recently selected hierarchy.
Measurements and measurement series can only be saved after measurement has been completed. Mea­sured values can only be added to intermediate buffer memory during a measurement. Customer, location and other entries cannot be changed in the memory menu. These have to be selected directly in the database and entered or changed.
