• Specified test

SECUTEST BASE(10), SECUTEST PRO and SECULIFE ST BASE test instruments fulfill the requirements of the applicable EU guidelines 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 VDE 0404,

DIN VDE 0413 parts 2 and

4, DIN EN 61557-16/VDE 0413-16 . 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.

(Mains power is discon-

nected if leakage current exceeds approx. 10 mA.)

The function test may only be performed after the DUT has successfully passed the safety test!

• 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.

GMC-I Messtechnik GmbH 5

Opening the Instrument / Repairs

Attention!

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.

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 – Course of action

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:

DUT: Turn the DUT off via its own switch.

2) Tes te r:

After measurement:

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

This device may not be disposed of with the trash. Further information regarding the WEEE mark can be accessed on the Internet at www.gossenmetrawatt.com by entering the search term “WEEE”.

Switching Power Consumers – Maximum Starting current

Our test instruments SECUTEST BASE(10), PRO and SECULIFE ST BASE allow for the active testing of devices with a nominal current (load current) of up to 16 A.

The test socket of the respective test instrument is equipped with 16 A fuses and the switching capacity of the internal relays also amounts to 16 A. Starting currents of up to 30 A are permissible.

In spite of the comprehensive safety measures against overload, starting currents of more than 30 A may result in accidental fusing of the relay contacts. In this case, the following error message appears: „L(N) fuse of the test socket is damaged“.

➭ Check the two fuses of the mains connection. Replace them

with new ones if they are damaged.

If the above error message persists, it may be assumed that the relays are damaged. In this case, the test instrument must be sent to our Service Center for repair (address see section 15).

Safer testing with Test Adapter

For devices under test which are expected to feature a starting current of more than 30 A, we strongly recommend the application of a test adapter for higher starting currents: e. g. test adapter of the AT3 series (AT3-IIIE, AT3-IIS, AT3-IIS32, AT16DI or AT32DI).

Alternative: Passive Testing

On the basis of the hazard assessment, it is also possible to perform a passive test (equivalent leakage current method) instead, i.e. without applying line voltage to the test socket.

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

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.

An error message appears if the ID cannot be converted to an RFID tag.

We are unable to offer any guarantees regarding the use of readers or writers other than those listed in the appendix.

4.1.1 Measurements in IT Systems (new parameter as of firmware 1.5.0)

Note

Attention!

Note

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 inspector 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.

Parameter Meas. at IT-mains can be set in the Setup menu: Setup 1/3 > All measurements > Meas. at IT-mains

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.

Notes on Parameter Inspector

– The inspector that has just been “selected” is included in the

tests performed as „Inspector“. None of the SECUTEST settings are stored specifically for the inspector – all settings in the SECUTEST are stored for the respective device and are available to all inspectors alike.

10 GMC-I Messtechnik GmbH

– If an inspector is protected by password, it only prevents those

users who do not know the password from “selecting” this inspector. When the test instrument is booted up, the password is not requested. The inspector remains selected even in the event of a power failure – a (password-protected) inspector can only be rejected by selecting another inspector. As of firmware 1.6.0: In order to delete an inspector whose password you do not know, it is sufficient to enter an incorrect password five times and to confirm the entry each time. Subsequently a query is issued as to whether the inspector is to be deleted. The inspector to be deleted may not be identical with the currently selected inspector.

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 database extension Z853R or with 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).

* only with database extension Z853R or with feature KB01

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 database extension Z853R or 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 database extension Z853R or 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.

Up to firmware 1.5.4:

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.

As of firmware 1.6.0:

The backup files on the USB stick 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. The test instrument accesses the backup file automatically.

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.

Data transfer to the PC (ETC) should not be started during single measurements or test sequences.

GMC-I Messtechnik GmbH 13

Backup/Restore to/from USB Flash Drive Firmware 1.7.2: Backups can only be restored within the

same firmware revision level. If the firmware has been updated between backup and restoring, the database is no longer valid. As of firmware 1.8.0: It is also possible to restore backup files created with previous firmware versions.

5.3.1 Keyboard Entries via Softkeys or External Keyboard

After selecting ID or any other object parameter, a keyboard is displayed which allows entry of alphanumeric characters via the fixed function keys and the softkeys. Alternatively, entries can also be made with the help of a USB keyboard or a barcode scanner which is connected to the instrument.

The keyboard layout can be matched to the language in SETUP. SETUP 2/3 > Culture > Keyboard Layout (for alphanumeric entries)

In order to operate an external USB keyboard successfully at the SECUTEST..., it is imperative that the settings for the keyboard layout which have been entered in the setup for “keyboard layout” conform to the connected keyboard.

Procedure (example: entering a DUT designation):

1 Switch the keyboard to uppercase, lowercase or special char-

acters with the abc key (Abc, ABC, Symb).

2 Select the desired alphanumeric character or a line break with

the scroll keys (left, right, up and down). The selection cursor can be accelerated by pressing and holding the respective scroll key.

3 After pressing the key, the respective character appears in the

display field.

4 Repeat steps 1 through 3 until the complete designation is

shown in the display field.

5 The designation in the display field can be changed subse-

quently after hiding the bottom keyboard by pressing the key. The cursor position can then be changed in order to delete individual characters.

6 After pressing the green checkmark, the selected char-

acter string is saved.

5.3.2 Data Entry via Touch-Screen Keyboard SECUTEST PRO or instrument with feature E01)

GMC-I Messtechnik GmbH 17

6 Connecting the Device Under Test

Note

➭ Connect the DUT in accordance with the schematic diagrams

included in the online help function.

Connection of the DUT to the test instrument depends upon:

• The type of DUT:

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 measurement of protective conductor resistance or with the direct measuring method for the touch current measurement)

For connection via adapter

– With single-phase extension cords via the EL1 adapter

(in which case the EL1 is connected to probe sockets P1)

via the

– With single and 3-phase extension cords

to the test socket

– Devices with 5-pole, 16 A CEE plug

via the AT16-DI differential current adapter to the test socket

– Devices with 5-pole, 32 A CEE plug

via the AT32-DI differential current adapter to the test socket

• DUT protection class (PC I, PC II or PC III) or any combinations of protection classes

The DUT must be switched on for all tests. Switches, relays, temperature regulators etc. must all be taken into consideration.

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 and Test Sequence

Alternative

The reference (line) voltage is the voltage to which the measured values for leakage current have been standardized.

It is used for the arithmetical adjustment of current measuring values of leakage current to the specified voltage.

Measurements with line voltage at the test socket: The setting value has no influence on the voltage the DUT is supplied with via the test socket of the SECUTEST.

Leakage current measurements with „Alternative“ method: The setpoint value of the synthetic test voltage is derived from the value specified here.

VL2E adapter

Defining Test Frequency „Alternative“

Variable frequency setpoint value for synthetic test voltage for all leakage current measurements of measurement type „Alternative“, affecting the following measurements and/or rotary selector switch positions:

– individual measurements (green rotary switch level) – measurments in test sequences predefined ex factory – measurements in user-defined test sequences (only with

database extension Z853R or feature KB01)

Parameter Test freq. Alt. can be configured in the Setup: Setup 1/3 > All measurements > Test freq. Alt.

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.

Note

Attention!

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

6.8 Connection Tests Conducted by the Test Instrument

The following measurements are performed automatically when the DUT is connected to the test instrument.

• Detection of Probes / Measurement Cables During individual measurements / automated test sequences, checking is conducted to determine whether or not the measuring sockets required for the measurement/sequence are occupied.

•

DUT connection detection

With the rotary switch in the AUTO/A1-A8 position, the “Test Socket” connection type is selected automatically (if correspondingly configured), if a mains plug is detected in the test socket.

•

Protection class detection

the rotary switch in the AUTO/A1-A8 position, protection class I or protection class II is selected automatically (if correspondingly configured), depending on the detected type of mains plug.

•Short-Circuit Test

Before switching mains voltage to the device under test: test for short-circuiting between L and N or L/N and PE. If applicable additionally as “inspection test step” in automated test sequences.

•

connect neutral conductor N inside the device under test.

Touch Current Measurement (absence of voltage)

Make sure that the contacted parts are not grounded.

6.6 2nd 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.

6.7 Connection Prompts

If a single measurement (green rotary switch positions) or a specific (integrated) automated test sequence (orange rotary switch positions) is started, checking is conducted to determine whether or not all of the probes and measurement cables required to this end are connected (depending on the configuration level of your SECUTEST...). If this is not the case, you’re prompted to connect probes, measurement cables or the test adapter to the SECUT-

EST....

Checking is only conducted to determine whether or not the corresponding sockets are occupied – make sure that suitable accessories have been connected for the selected measurement/ connection type.

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

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.

Test Sequence with Connection to the Test Socket

Note

➭ Set the rotary switch to the RPE position. ➭ Select measurement type or connection type, and test cur-

rent. After pressing the Ip key, you have direct access to the test current parameters: each time this key is pressed, the setpoint value shown in the measuring window is switched to the next value.

➭ Connect the DUT to the test socket. ➭ Start the test: press the START/STOP key.

➭ Contact all conductive parts which are connected to

the protective conductor with test probe P1.

During measurement, the connector cable must only be moved to the extent to which it’s accessible during repair, modification or testing. If a change in resistance occurs during the manual test step of the continuity test, it must be assumed that the protective conductor is damaged, or that one of the connector contacts is no longer in flawless condition.

➭ The measured values are displayed. The measured

value recording symbol shown at the right appears. Each time this key is pressed, the currently displayed measured value is saved to the buffer.

➭ Stop the test: press the START/STOP key.

The save symbol appears (floppy disk showing the number of measured values stored to buffer memory) and prompts you to save the measured values to an ID number.

➭ Read the measured values and compare them with the

table of permissible limit values.

➭ Press the ESC key in order to discard the measured

values stored to buffer memory and acknowledge by pressing the key shown at the right.

Special Case: Testing Protective Conductor Resistance at PRCDs (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) ➭ 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.

Special Case: Testing Extension Cords

➭

Set the measurement type parameter to “PE(TS) – P1”.

➭ Connect the EL1 adapter to the P1 sockets at the test instru-

ment.

➭ Connect the plug at the end of the extension cord to the test

socket.

➭ Connect the coupling socket at the end of the extension cord

to the plug at the EL1 adapter.

➭ Same test sequence as described above.

Further options for testing extension cords are included in the description of single measurements in the EL1 switch position and under automatic test sequences in switch position A8.

However, there are two parallel measuring circuits for the RISO measurement with the LN(PD) – P1//PE(PD) measuring parameter, which are established simultaneously to the short-circuited L and N conductors: one insulation resistance is measured via PE at the test socket and, at the same time, a second insulation resistance is measured via test probe P1.

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, medical devices etc. Leakage current measurements must be performed for these DUTs (see Section 8.7). Observe the notes in the service instructions.

In order to prevent damage to the instrument, measurement of insulation resistance may only be performed between application parts, measurement inputs or interfaces and the protective conductor or the housing if the instrument is laid out for measurements of this type.

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 5 with regard to

switching power consumers.

• CEE adapter (only for connection via single-phase CEE or “caravan socket”)

• AT3 adapter (AT3-I IIE, 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

socket.

➭ Start the test: press the START/STOP key.

➭ Acknowledge the warning which indicates that line

voltage will be connected to the test socket.

➭ The measured values are displayed. The measured

value recording symbol shown at the right appears. Each time this key is pressed, the currently displayed measured value is saved to the buffer.

➭ Stop the test: press the START/STOP key.

These or similar adapters can be used for the function test (initial start-up of the DUT), but measurement of apparent and active power, power factor and current consumption is only possible when the DUT is directly connected to the test socket or via the CEE adapter (single-phase CEE socket only).

10.1 General

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.

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.

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, A1 to A8 switch positions:

• 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.

Test Sequences in Switch Positions AUTO, A1 to A8

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. The measurements and parameters available in your SECUTEST version are loaded from the test instrument and provided in the PC software for this purpose. Finally, the created test sequence can be loaded directly into the SECUTEST... (prerequisite: database extension Z853R or feature KB01) and saved to the computer as an XML file. As a rule, customer-specific (user-defined) test sequences are identified with a prefixed asterisk on the SECUTEST user interface.

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.

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.

General Settings (Setup: auto measurements parameter)

Note

SETUP

The following settings can be entered for all test sequences in the

SETUP switch position on menu page 1/3 under the auto measurements parameter:

❑ At the End of the Sequence

At the end of a sequence, either the save symbol appears in order to prompt storage (“memory screen” parameter), or the results list (“results list” parameter) is displayed.

❑ 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

Yes

is selected, the test instrument detects whether or not the protective conductor is contacted with the probe during the protective conductor resistance measurement included in an automated test sequence 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.

Note

Error Messages Possible Causes Corrective Measures

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. (Make absolutely sure that direct leakage current measurements are possible in your current mains type!)

➭ Operation in an IT system: Re-

In the case of DUTs which are intended

for operation at an outlet that’s pro-

tected with a 16 A fuse, a short-circuit

may be detected under certain circum-

stances if, for example, they include a

PTC resistor (e.g. large floodlights).

Be sure to use a 3-phase test adapter

in order to test devices of this sort (e.g.

the AT3-IIIE). ➭ You can skip over this short-circuit

– A device under test is connected to

the SECUTEST and has been started up, whose leakage current (measured by means of the differential current method) exceeds the limit value specified in setup.

– The fuse for the test socket’s L

conductor has blown (fuse link 2).

➭ If the device under test normally

generates a leakage current of greater than 10 mA (e.g. large heaters), temporarily increase the “residual current protection” value selected in setup to 30 mA and try again.

➭ If values of this magnitude are not

to be expected for the respective device under test, or if the “residual current protection” value has already been set to 30 mA in setup, there may be a ground fault at the DUT.

➭ Disconnect the test instrument

from the mains and inspect the fuses next to the SECUTEST’s mains connection.

– The fuse for the test socket’s N

conductor has blown (fuse link 1).

– One of the two fuses for the test

socket has blown (fuse link 1 or 2).

– A short-circuit has been detected

” application, which is integrated into the firm-

13.6 Recalibration

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 downloaded from the mygmc page of our website as a ZIP file, if you have registered your test instrument:

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.

13.5 Fuse 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.

13.7 Technical 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 IEC 61557-16/VDE 0413-16. 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:

➭ Connect the SECUTEST... to a multiple distributor. ➭ Conduct a touch current measurement for permanently con-

nected DUTs (nothing may be connected to the test socket).

➭ Measure protective conductor resistance between the neigh-

boring socket at the multiple distributor and the test socket.

➭ The measured value may not exceed 0.3 Ω.

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.

The connected USB storage medium must fulfill at least the following requirements in order to be applied with your test instrument:

• The file system on the USB flash drive is formatted for FAT (FAT16/FAT32). NTFS or exFAT file systems are not compatible, for example.

• Maximum power consumption of the USB storage medium via the USB port may not exceed 500 mA.

• Do not use any USB storage devices with encoding functions.

Furthermore, you should ensure that the USB drive features an LED display which indicates whether a write operation has already been completed.

Barcode scanners with Bluetooth interface are in preparation.

Important Notes

• Status/visibility: For reasons of safety, we recommend deactivating the Bluetooth interface if it is not required. The setting „not visible“ does not make deactivation of the Bluetooth interface redundant as invisible Bluetooth devices can actually be localized with the appropriate means.

• Device couplings which are not required for an extended period of time should be deleted.

•The device name of the DUT has been set at SECUTEST by default. If you access one PC with several test instruments, we advise you to supplement the name to facilitate assignment: SECUTEST1, SECUTEST2, etc.
