2 Safety Features and Precautions

SECUTEST BASE(10), SECUTEST PRO and SECULIFE ST BASE(25) test

instruments fulfill all requirements of applicable EU directives 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,

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 instrument.

Tests may only be performed by a qualified electrician, or under the supervision and direction of a qualified electrician.The user must be instructed by a qualified electrician concerning performance and evaluation of the test.

Suitable personal safety equipment is required. If you use active or passive body assistance, please consult your

physician or the manufacturer of the body assistance device.

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

• 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 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 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 or the test probe are touched, electrical shock may occur which could result in consequential accidents.

devices

GMC-I Messtechnik GmbH 5

• Probe Test

Attention!

Test the probe after completing each test (see also section 10.2.2).

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 voltage-free, i.e. the instrument must be disconnected from mains supply power and may not be connected to a measuring circuit. The fuse type must comply with the specifications in the technical data or the labeling on the instrument.

Opening the Instrument / Repairs

The instrument may only be opened by authorized, trained personnel in order to ensure flawless operation and to assure that the guarantee is not rendered null and void.

Even original replacement parts may only be installed by authorized, trained personnel.

If it can be ascertained that the instrument has been opened by unauthorized personnel, no guarantee claims can be honored by the manufacturer with regard to personal safety, measuring accuracy, compliance with applicable safety measures or any consequential damages.

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

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.

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:

Before opening the housing, pull the mains plug out of the outlet and wait for at least 5 minutes.

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:

Device under test: Turn the DUT off via its own switch.

2 Test instrument: 3

Device under test: Turn the DUT on via its own switch.

After measurement:

Device under test: Turn the DUT off via its own switch.

5 Test instrument:

Switch line voltage to the test socket.

Deactivate line voltage to the test socket.

Switching Loads – Maximum Starting Current

Our SECUTEST BASE(10), PRO and SECULIFE ST BASE(25) test instruments permit active testing of devices with a nominal 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.

3.5.3 Report Tapes from Thermal Printers

Note

Report tapes can be printed out with the Z721S thermal printer (accessory: Z722S thermal paper).

As of firmware V2.1.1: The test report can now be edited and a company logo can be added to it directly in SETUP at the test instrument (see page 14). A company logo can be loaded from a USB flash drive for which the following image file formats are supported:

BMP, JPG, PNG or GIF, resolution: max. 800 x 800 pixels. Color

depth: max. 24-bit.

Report Designer PC software is no longer supported as a firmware version 2.1.1.

3.5.4 Printing via IZYTRONIQ

Alternatively, stored measurement data can be read into IZYTRONIQ report generating software at a PC and printed out as a

report.

Code Recognition Please make sure that the printed codes are recognized by your scanner. Some code types have to be activated on your scanner prior to being used (this is frequently the case with Aztec/DataMatrix).

Minimum Width of Labels

Tape cartridges with a minimum width of 12 mm are recommended for print-out of 2D code labels (QR code, MicroQR code, DataMatrix, Aztec). If a blank label is discharged upon printing an ID number as a 2D code with a 9 mm ribbon cartridge, replace it with a 12 mm cartridge (or wider) and restart the printing process.

3.5.5 Saving Reports to a USB Flash Drive

Select a measurement from the database view (MEM key) with the scroll keys, for which a report will be saved to a USB flash drive. Then press the PRINT key. “Print job finished” appears. The report is written to an HTML file. The filename consists of the timestamp and the ID of the test object. Alternatively, reports can be save or printed out immediately after conducting a test, or when the test list view is open.

A list of suitable USB flash drives is included in the appendix (see section 14).

3.6 Print-Out of ID Labels (as of firmware V1.3.0)

A barcode printer permits for the following applications:

• Print-out of ID numbers encrypted as barcodes for devices under test – for quick and convenient acquisition during periodic testing

• Print-out of repeatedly occurring designations such as test object types encrypted as barcodes in a list, allowing them to be read in as required for comments

We’re unable to offer any guarantees regarding the use of printers other than those listed in the appendix.

3.7 Writing RFID Tags (as of firmware V1.5.0)

The following function is made possible by an RFID scanner (programmer):

• Read-out of encrypted ID numbers for devices under test to an RFID tag for quick and convenient read-in during periodic testing

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 via the mains plug.

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 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 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 measurements 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 “Measurement at IT mains” option has been activated in SETUP.

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.

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 carrying voltage (in accordance with the first two mentioned cases), 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.

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 measurements.

• The type of DUT:

For direct connection to the test socket (TS)

Devices with single-phase connection and 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)

Measurement of protective conductor current

(only possible with feature I01)

For connection via adapter

– With single-phase extension cords via the EL1 adapter

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

– With single and 3-phase extension cords

Selectable 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:

– Single measurements (rotary switch level: green) – Measurements included in predefined default test sequences – Measurements included in user-defined test sequences (only with

database extension, feature KB01, “Z853R – SECUTEST DB+”)

The Alternative Test Frequency parameter can be set in Setup: Setup 1/3 > All Measurements > Alternative Test Frequency

6.3 Manually Specifying the Connection Type for Single Measurements

In the case of single measurements the test instrument is unable to detect the respective connection type (e.g. test socket or permanent connection (voltage measuring inputs)). The connection type must be specified manually.

➭ Select parameter settings.

➭ After selecting the measurement type parameter, a list of possi-

ble connection types is displayed.

➭ Select a connection type.

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 Reference Voltage L-PE and Alternative Test Sequence

Specifying Reference Voltage L-PE

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

It’s used in the case of leakage current for mathematical adaptation of measured current values to the specified voltage.

Measurements with line voltage at the test socket: The setting value has no influence on the voltage with which the test object is supplied 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.

The displayed measured values for leakage current are standardized to an adjustable reference value (typically 230 V) in order to permit reproducible measurement of leakage current even with fluctuating mains supply voltage

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 Category for Automatic Test Sequences

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

6.5 Special Conditions

Note

Attention!

Protection Category II Devices with Protection Category I Mains Plugs

If the device under test is equipped with a protection category I plug although it complies with protection category II, protection category I is recognized by the test instrument. If this is the case, switch the protection category 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

Auto Measurements”

“

submenu via the “

SETUP

switch position in the

” parameter.

Protective Conductor and Insulation Resistance Measurements for Permanently Installed Devices Under Test

Deactivate the electrical system which supplies power to the device under test before connecting the test instrument!

➭ Remove the mains fuses from the device under test and dis-

connect neutral conductor N inside the device under test.

Touch Current Measurement (absence of voltage)

Make sure that the contacted parts are not grounded.

6.6 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, RINS and equivalent leakage current.

Measurements with test probe 1 to 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.

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.

•

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 test object (= device or ME device (medical electric device)). 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 – preselection of an existing ID

You’ve already set up a test structure in the test instrument or uploaded one with the help of report generating software. Open the database view before starting the measurement by pressing the MEM key. Then select the test object or its ID within the test structure by pressing the respective scroll key. Exit the database view (MEM navigation) by pressing ESC 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 a previously saved 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 report generating software. You perform the measurement without first opening the database. No test object 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 test object’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 test object selected!” Press the ID key in order to enter the test object’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 test object. – Selection : 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.

– Selection : If you press , the display is switched to the

database view (MEM navigation). You can go to the next page (Edit Objects 2/3) by pressing , and then enter a new test object. Press to this end. All possible object types are displayed. Press Device. 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 test object is displayed inversely in the structure. Press ESC 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.

in order to return to the SAVE

7.1 QuickEdit Function – QEDIT (feature KD01, “Z853S – SECUTEST DB COMFORT”)

QuickEdit is available whenever you search for a test object ID and the ID doesn’t already exist in the database.

The following search options are available: – Via the ID softkey in the test sequence (AutoTest) or in the

save menu of the manual test

– ID search via ID softkey on page 3 of 3 of database manage-

ment MEM

– Read-in of a test object ID via the barcode or RFID scanner

If the searched for ID is not found, the following question appears. When creating a new object you can first of all choose between a (standard) test object ( icon) or a medical test object – “new ME device” in (staff of Aesculapius icon ) by pressing the (1) key.

If you select QEDIT (Quick Edit function), key (2) (shown against a green background and not crossed out), you proceed directly to the memory management entry window by confirming with , in order to create a new test object and enter further properties.

After confirming with , the location of the ID in the database is displayed. Measurement results are saved to memory after pressing the Save key once again.

Entering and Deleting Offset Values

The test instrument determines protective conductor resistance by means of a 4-pole measurement. If measurement cables or extension cords are used whose ohmic resistance should be automatically subtracted from the measurement results, there are two ways to save the respective offset value in the RPE switch position:

• Entry via the numeric keypad

• Acceptance of the momentary measured value by pressing the

OFFSET

softkey

SET

Proceed as follows in order to accept the measured value:

➭

Start the measurement and wait until the measured value settles in.

➭ Press the

SET OFFSET

key. The value is transferred to the offset

field.

The entered or accepted offset value is permanently stored and is subtracted from all protective conductor resistance values measured in the future. This applies to single measurements as well as to measurements conducted in the AUTO switch positions. The symbol is displayed in the header in all switch positions until the offset value is deleted by pressing the CLEAR OFFSET softkey (R

switch position).

Protective Conductor Current Measurement with 25 A AC

In accordance with IEC 60601, at least 25 A must be achieved with a load of 0.1 Ω and a maximum voltage of 0.6 V.

Continuous protective conductor resistance measurement with a test current of 25 A is not possible due to contact resistance at the jacks.

If the test instrument is operated at room temperature, an uninterrupted test duration of at least 15 seconds is possible. Under other conditions, maximum test duration may be shorter and/or the measurement may be prematurely terminated.

Suitable measurement cables with a minimum cable cross-section of 2.5 mm must be used when measuring protective conductor resistances with a “25 A AC” test current. Included with the SECULIFE ST BASE25: suitable test probe with green strain relief sleeve. For subsequent orders, we recommend the SK2-25A test probe (Z746C). Under certain circumstances, the required standard values might not be complied with if unsuitable accessories are used.

Measurement duration with a 25 A test current is limited (see technical data). An error message is generated if measurement duration is exceeded which results in a temperature increase at the test instrument.

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 buffer memory.

➭ End 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 a standard test probe as an al-

ternative) to the P1 sockets at the test instrument.

➭ Connect the PRCD to be tested to the test socket via its plug. ➭ 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= measure- ment types, test current rises very slowly in order to prevent triggering of residual current monitoring at the PRCD. And thus with this measurement type, it may take longer than usual until a valid measured value is displayed. For this reason, the protective conductor should not be contacted manually with the test probe, in order to prevent a sudden rise in test current resulting in inadvertent tripping of the PRCD.

Prerequisite for Testing The measurement of insulation resistance may not be conducted on protection category 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.

Direct Measuring Method – Direct measurement type – DUT mains plug to test socket

Schematic Diagram

The device under test is operated with mains power. Protective conductor current is measured between the protective conductor at the mains and the protective conductor terminal at the DUT via the DUT’s mains cable.

Wiring Diagram

Definition of Protective Conductor Current (direct measurement)

Current which flows through the protective conductor in the case of housings which are isolated from ground.

Definition of Differential Current

Sum of instantaneous current values which flow via the L and N conductors at the device’s mains connection. Differential current is practically identical to fault current in the event of an error. Fault current: current which is caused by an insulation defect, and which flows via the defective point.

Definition of Alternative Measuring Method (equivalent leakage current)

Equivalent leakage current is current which flows through the active conductors of the device which are connected to each other (L/N) to the protective conductor (SC1), or to the exposed, conductive parts (SC2).

Differential Current Measuring Method

The device under test is operated with mains power. The sum of the momentary values of all currents which flow through all active conductors (L/N) at the mains side of the device connection is measured. The measurements must be performed with mains plug polarity in both directions.

Alternative Measuring Method (equivalent leakage current)

A high-impedance power supply is connected between the shortcircuited mains terminals and all exposed metal parts of the housing (which are connected to one another). Current which flows over the insulation at the device under test is measured.

The PRCD under test is plugged into the test socket at the test instrument. The PRCD’s phase conductor must be contacted with test probe P1 in order to trip the PRCD.

Testing of PRCDs (test sequences and time to trip) is only possible for DUTs with a nominal voltage of 230 V.

Measurement of time to trip is not possible in IT systems.

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 category 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.

The following connection types are possible:

• Test socket

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

AT3 adapter (AT3-IIIE, AT3-IIS, AT3-IIS32)

•

• AT16DI/AT32DI

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).

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.

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.

The go/no-go evaluation of the measured values is performed with greater accuracy than the value which appears at the display, which may lead to the fact that, due to the missing decimal places, a measured value which appears at the display may seem to correspond exactly to the limit value although it’s highlighted in red (as a limit value violation) due to the places to the right of the decimal point.

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 through 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 to 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) and the SECULIFE ST BASE(25) in rotary switch positions AUTO and A1 to A8:

• DIN VDE 0701-0702 Periodic testing and testing 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.

User-Defined Test Sequences

Up to 24 * customer-specific (user-defined) test sequences can be saved to the test instrument and assigned to rotary switch positions AUTO and A1 to A8. The sequences are created at the PC with the help of IZYTRONIQ software (up to firmware 1.7.2: Sequence Designer software). The measurements and parameters available in your SECUTEST version are loaded from the test instrument and made available in the PC software for this purpose. Finally, the created test sequence can be loaded directly to the SECUTEST... (prerequisite: database extension, feature KB01, “Z853R – SECUTEST DB+”) and saved to the computer as an XML file. As a rule, customer-specific (user-defined) test sequences are identified with a preceding asterisk (*) in the SECUTEST user interface.

* As of firmware version 2.0, a tota l of 24 user-defined test sequences can be loaded

to the test instrument with feature KB01, “Z853R – SECUTEST DB+”.

10.2 User-Defined Test Sequences / Remote Control

Note

Attention!

Note

SETUP

(only with feature KB01, “Z853R – SECUTEST DB+”)

10.2.1 General

When creating user-defined test sequences, the author of the test sequence can define and configure individual test steps himself, and specify the order in which they’re run.

With the help of IZYTRONIQ sequences can be created at the PC and transferred to the test instrument via a USB port.

Up to 1200 test steps can be distributed to as many as 24 test sequences and saved to memory at the test instrument.

Similar options are available to the user when the test instrument is remote controlled (e.g. via IZYTRONIQ IZY remote test sequences).

Some of the test steps necessitate advance testing in the form of inspections or test instructions, for example so that the inspector has enough time to contact the respective location with the probe at the point in time of test execution, or to set the DUT to the appropriate state.

If user-created test sequences are created and/or used, or in the case of remote control of the test instrument, the creator of the test sequences or the user/inspector assumes responsibility for standards-compliant test steps and execution of advance tests in the correct order.

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.

PC software (as of firmware 2.1.1), test

10.2.2 Testing of Probe Connection P1 and Probe Fuse P1

If probe P1 is used in a test sequence, a “Probe Test” step with “Probe: Probe Connection P1” must be included in the respective test sequence. Background: In addition to assuring that a probe is connected to probe connection P1, the probe test at connection P1 also determines whether or not the probe’s fuse link is intact.

If the fuse at test probe P1 is defective, all subsequent measurements using this measuring path are incorrectly evaluated as good!

Automatic Measurements (1/3)

❑ 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

If Yes is selected, the test instrument detects whether or not the protective conductor is contacted with the probe during the protective conductor resistance measurement of an automatic 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.

The “Auto Measuring Point” function is only activated during test steps of the “multiple measurement” type. If you want to use this function ... – In the case of integrated test sequences: Make sure

that the “multiple measurement” test parameter (see page 54) is selected for the RPE test step.

– In the case of user-defined test sequences (only with

database extension, feature KB01, “Z853R – SECUTEST DB+”): make sure that the RPE test step has been entered to the sequence as a “multiple measurement”.

Automatic Measurements (2/3)

❑ Initial Window Style

Selection can be made here between a tree view and a detail view for the first page of the test sequence (see section 10.4).

❑ Limit Value Mode

If you want to use only the limit values specified in the standards to evaluate the measurements, set the parameter to Normal. When set to Expert, the LIMIT softkey appears next to the “measurement failed” popup if the measurement has not been passed. This key makes it possible to enter a user-defined limit value (as a rule a limit value specified by the manufacturer which deviates from the standard), in order to allow the test to be passed under these new conditions.

Entry of a user defined limit value is not possible if “Continue” is selected for the “Limit Violation” option.

10.3 General Settings (Setup: auto measurements parameter)

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 (see section 4.3):

GMC-I Messtechnik GmbH 59

❑ Limit Value Violation (only with feature KD01, “Z853S – SECUTEST

DB COMFORT”)

With its “Try Again” operating mode, the test instrument makes it possible to immediately restart the failed test step and repeat the measurement in the event that a limit value is violated.

In the “Continue” mode, the test instrument doesn’t terminate the test sequence in the event of a limit value of violation, and instead continues testing despite any individual steps which have failed.

If a limit value violation occurs during the test sequence, the respective test step designation appears in red in the header for all following test steps, so that it’s already

made apparent during the test sequence that a limit value

Note

violation has occurred during one of the previous test steps, and that the device under test will not pass testing.

Automatic Measurements (3/3)

❑ Measuring sequences (no longer in the “Culture” menu as of firmware

V1.6.0)

The following standards can be selected here: VDE, OVE (Dutch version: NEN) The instrument is restarted if the setting for “Measuring Sequences” has been changed and the “Auto Measurements” menu is exited.

The test instrument must be restarted after changing the measuring sequences. Database structure and content remain unchanged.

❑ Autostore (feature KD01, “Z853S – SECUTEST DB COMFORT”)

If this function is activated (“on”), the test results for the automatic test sequence are immediately saved under the test object (= device or ME device (medical electric device)) which is currently selected in the database.

If you haven’t yet selected a test object in memory management (MEM key), a message appears informing you that automatic storage of the current test is not possible.

You’re prompted to enter an object ID via the scanner or the softkeys, or to select one from the database (MEM key). In this case you have to save the test manually to the database via the “Save” softkey.

❑ Skip steps

Here you can configure whether or not the user is allowed to skip test steps during a test sequence (“on”).

This does not apply to inspection test steps that can be omitted (which have no relevance with regard to the standard)!

10.8 Executing and Evaluating Test Steps

Manual evaluation of visual inspection

(prerequisite: “visual inspection” sequence parameter is preset to “on”.)

➭ Evaluate the visual inspection. ➭ If you mark even one visual inspection as not passed

with the key shown at the right, the sequence is aborted and the test is evaluated as not passed.

➭ Resume the test sequence.

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 the safety test (protective conductor resistance and insulation resistance measurements)!

Do not start measurements at your test instrument unless it’s in plain view. Do not connect line voltage to the test socket of your test instrument before the surrounding area has been secured.

Test Steps with Manual Evaluation (e.g. RPE)

If the fuse at test probe P1 is defective, all subsequent measurements using this measuring path are incorrectly evaluated as good!

• Insulation test (whether or not the DUT is set up in a well-insulated fashion)

• On test and short-circuit test (prerequisite: “short-circuit test L-N” sequence parameter is preset to “on”. In order to be able to detect a short-circuit at the DUT, testing is conducted between L and N, as well as LN and PE.

If you deselect important test steps under sequence parameter (set to off), the test sequence might not fulfill the requirements stipulated by the standard any more.

If you have set the “ respective test sequence to “Always accept” and the “

Attention!

Limit value violation

Note

 

If the measured value appears red at the display, a limit value has been violated. If you nevertheless start the evaluation procedure, an error message appears. You have the option of repeating the evaluation procedure. If Continue is selected for the “Limit Violation” option in SETUP (Auto Measurements 2/3), the test instrument continues testing despite any limit value violations. In this case, the device under test is operated with line voltage despite any insulation faults or the like. Make sure that the device under test is secured, in particular against contact during the testing process.

Regarding the test sequence in switch position A6/A7: Section 5.2 of DIN EN 60974-4expressly stipulates that the cables have to be bent and twisted over their entire length during the measurement, in particular in proximity to the cable glands, in order to be able to detect any interruptions of the protective conductor.

10.9 Setting Limit Values Manually

If “Expert” is selected instead of “Normal” in setup under “Auto Measurements” in the “Limit Value Mode” submenu, the LIMIT softkey appears next to the “measurement failed” popup. This key makes it possible to enter a user-defined limit value (as a rule a limit value specified by the manufacturer which deviates from the standard):

Selecting “Continue” or “Try Again” rules out the possibility of entering a limit value.

10.10 Ending the Test Sequence

“Sequence finished” appears at the display.

Initial Display (memory screen)

The measured value is ascertained automatically within a specified period of time. The evaluation cycle is visualized as follows: the progress bar starts at the left-hand edge of the display and moves to the right. When it reaches the rightmost position, evaluation has been completed. The test sequence is then automatically resumed.

Manual Evaluation of the Function Test

(prerequisite: “function test” sequence parameter is preset to “on”.

➭ Evaluate the function test: ➭ If you mark the function test as not passed with the

softkey shown at the right, the sequence is aborted and the test is evaluated as not passed.

➭ If you evaluate the function test as passed, you can

simply continue with the test sequence.

In either case you can enter a comment, which can be subsequently edited as well.

11.1 List of error messages

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” onpage 10).

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

tion, e.g. after transport in low outdoor temperatures and subsequent operation in a warm indoor environment, it’s advisable to wait until the test instrument has acclimatized before starting any measurements.

If the test instrument is colder than the ambient air, condensation may occur at high humidity, i.e. condensate may accumulate on components. This could result in the occurrence of parasitic capacitances and resistances which, in turn, affect the measuring circuit and measuring accuracy.

13 Maintenance

Attention!

Note

Attention!

13.1 Housing Maintenance

No special maintenance is required for the housing. Keep outside surfaces clean. Use a slightly dampened cloth for cleaning. Avoid the use of cleansers, abrasives and solvents.

13.2 Testing the Color Display and the Buzzer (self-test parameter)

The color display can be tested for failure of individual segments and loss of color components on page 3/3 of the setup menu in the SETUP switch position under the self-test parameter.

Beyond this, the buzzer can be tested for 3 different frequencies.

13.3 Software Update (system info parameter)

The current firmware or software version can be queried via the system info parameter (Setup 3/3).

The test instrument’s firmware can be updated via the USB port with the help of a PC. Updating is only possible via the proprietary Firmware Update Tool application.

➭ Before updating your test instrument’s firmware, make sure

that your PC software is compatible with the current firmware version (see table below).

Te st Instrument Firmware Version

1.8.1 ETC .etc ✔✔

1.8.2 ETC .etc ✔ 1.5

1.8.3 ETC .etc ✔ 1.5

2.0.0 IZYTRONIQ .etc ✔ IZYTRONIQ

2.1.1 IZYTRONIQ .secu

As a registered user (if you’ve registered your test instrument), you’re entitled to download the Firmware Update Tool and the cur- rent firmware version free of charge from the myGMC page at www.gossenmetrawatt.com.

You’ll also find operating instructions for the firmware update tool here.

PC Report Generating Software

Before updating the firmware, be sure to save the structures you have created and your measuring data, because they might be deleted during the update process (see section 5.2.3, “Backing Up and Restoring Test Structures and Measurement Data”).

Adjustment data are not overwritten during updating, and thus recalibration is unnecessary.

The interface cable may not be disconnected while updating the firmware via the USB port.

(see Section

3.5.3)

IZYTRONIQ

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 the 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.

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 on our website:

www.gossenmetrawatt.com (

→

COMPANY → Quality and Certificates → DAkkS-calibration center).

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.

* Examination of the specification, as well as adjustment, are not included in calibra-

tion. 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 neighboring 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

The test instrument may not be disconnected from supply power while updating the firmware via the USB port.

13.4 Backup Battery for Real-Time Clock

The backup battery (lithium cell) should be replaced no later than after 8 years. Replacement can only be executed by the service department.

GMC-I Messtechnik GmbH 83

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 SECUT-

Note

EST..., 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.

13.8 Returns and Environmentally Sound Disposal

The instrument is a category 9 product (monitoring and control instrument) in accordance with ElektroG (German electrical and electronic device law). This device is subject to the RoHS directive. We also make reference to the fact that in this regard, the current status can be accessed on the Internet at www.gossenmetrawatt.com by entering the search term WEEE.

We identify our electrical and electronic devices in accordance with WEEE 2012/19/EU and ElektroG using the symbol shown at the right per DIN EN 50419.

These devices may not be disposed of with the trash. Please contact our service department regarding the return of old
