Probe connection

Insert the double plug of the probe into sockets 4 and 5 such that the plug with the white ring contacts socket 5 (vertical bar).

Note: Contact problems with 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 so that the surface has a metallic shine. The tip of the test probe is not suitable for scratching away paint, because this may impair its coating and/or mechanical strength. The brush probe (Z745G) may be more suitable than the test probe in certain individual cases.

Measurements at jacks 1 – 2 – 3

2 Safety Features and Precautions

Note

Attention!

This instrument fulfills the requirements of the applicable European and national EC guidelines. We confirm this with the CE marking. The relevant declaration of conformity can be obtained from GMC-I Messtechnik GmbH.

The test instrument has been 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 Part 2 and 4 and DIN VDE 0104 (Feature F02 or

Only when used for its intended purpose, the safety of the user, the test instrument and the device under test (electrical equipment or electrical medical devices) is assured.

Read the operating instructions carefully and completely before placing your test instrument into service, and 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 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 electrical systems with a maximum of 230 V +10% which 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 interruptions in cables or plugs etc.

• When using a probe with coil cable (SK2W): Grip the test probe firmly, for example after 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 This test is performed with a maximum voltage of 500 V, with a current

SECULIFE STHV)

limit having been set (I < 3.5 mA). However, contacting the terminals (3 or 2) causes an electric shock which, in turn, may result in accidents.

• Leakage Current Measurement

During leakage current measurement it is imperative to ensure that the device under test is operated at line voltage. Exposed conductive parts may be charged with hazardous contact voltage during the test and may consequently not be touched under any circumstances. (There is a power shutdown as soon as the leakage current is higher than approx. 10 mA).

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

Switching loads on and off

When switching the DUT on or off under load it is imperative that you adhere to the order indicated below. This helps to prevent excessive wear and tear of the mains relays at the test instrument.

Before the measurement:

1) DUT: Switch the DUT off at the proprietary switch.

2) SECULIFE ST or SECULIFE ST

3) DUT: Switch on the DUT at the proprietary switch.

After the measurement:

4) DUT: Switch the DUT off at the proprietary switch.

5) SECULIFE ST or SECULIFE ST

The measuring and test instrument may not be used:

• If it demonstrates visible damage

• With damaged connector cables, measuring cables or patient ports

• If it no longer functions properly

• After extraordinary stresses due to transport In such cases, the instrument must be removed from operation and

secured against unintentional use.

Meanings of Symbols on the Instrument

Attention!

The symbols on the instrument have the following meanings:

Warning regarding dangerous electrical voltage

Warning concerning a point of danger (Attention: observe documentation!)

Test socket

Mark of approval from VDE test authority

Indicates EC conformity

This device may not be disposed of with the trash. For further details on the WEEE marking, please refer to our website www.gossenmetrawatt.com and enter search term ’WEEE’.

2.1 Notes Regarding the High-Voltage Test (only Feature F02 or SECULIFE ST

The KS13 cable set, or similar cable sets, may not be used for the high-voltage test. The high-voltage test may only be performed directly via the test socket!

Do not hold the device under test in your hand during testing,

especially when testing safety class II devices. Make sure that the device under test does not make contact with any equipment or persons during testing.

Liability Exclusion In the event of sparkover, PCs operated in proximity to the test instrument may

“crash” resulting in data loss. All data and programs should be suitably backed up before high-voltage testing is performed, and computers should be shut down if necessary. A crash may occur even if no RS 232 connection has been established.

The manufacturer of the test instrument assumes no liability for direct or consequential damage to computers, peripherals or data which occurs during high-voltage testing.

The manufacturer assumes no liability for defects at the device under test which result from high-voltage testing. As a rule, defects can only occur at devices under test which are not in compliance with applicable standards, which were previously damaged or which have been improperly repaired, because high-voltage testing is required for type and routine testing by IEC 61010-1/EN 61010-1 / VDE 0411, part 1, as well as EN 60 335, EN 60601 and EN 60950.

Connection to the Mains

3.1 Connection to the Mains (115 V / 230 V, 50 Hz / 60 Hz)

õ Connect the mains plug at the test instrument to the mains power out-

let. 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.

5 Classification of Devices Under Test

5.1 Safety Classes

Devices assigned to all of the following safety classes are equipped with basic insulation, and provide for protection against electrical shock by means of various additional precautions as well.

Safety Class I Devices

Exposed, conductive parts are connected to the protective conductor so that they are not charged with voltage if the basic insulation should fail.

5.2 Application Parts (electrical medical devices)

Type B Application Parts (body)

Devices of this type are suitable for both internal and external patient applications, except for use in direct proximity to the heart.

These devices provide for adequate protection against shock especially as regards:

• Reliable leakage current

• Reliable protective conductor connection if utilized Devices of the following safety classes are allowable:

I, II, III or devices with internal electrical power supply.

Safety Class II Devices

These devices are equipped with double insulation or reinforced insulation.

Safety Class III Devices

and Devices with Internal Power Supply

These devices are powered with Safety Extra Low Voltage (SELV). Beyond this, no voltages are generated which exceed SELV. These devices may not be connected to the mains. They may only be connected to the test instrument at jacks 1 through 3.

Type BF Application Parts (body float)

Same as type B, but with type F insulated application parts.

Type CF Application Parts (cardiac float)

Devices of this type are suitable for use directly at the heart. The application part may not be grounded.

Devices of the following safety classes are allowable: I, II or devices with internal electrical power supply.

Note: The DUT may only be connected to jacks 1 to 3 at the test instrument. It is only possible to perform a visual inspection, a measurement of the insulation resistance or the supply voltage, see parameter “SC II I U on page 39.

”

Classification Parameter (in the Sequence ... menu)

The test instrument always performs testing in accordance with the strictest limit values of the respectively selected safety class. The test is failed if this limit value is exceeded.

However, higher limit values are allowed for certain devices under test. If the classification parameter has been activated (= x), the user is asked if

higher limit values are allowable for these devices. If the user responds with “Yes”, the DUT is reevaluated and the test may be passed.

Devices with Internal Power Supply

Devices with internal power supply are tested like permanently connected Safety Class II or II I devices.

9 Measuring Protective Conductor Resistance

Note



Connecting Safety Class I Devices to the Test Socket

When the DUT is connected, resistance is measured between the protective conductor terminal at the test socket or at the PE jack and the probe connection at the DUT (contact with conductive parts of the housing).

õ In order to measure protective conductor resistance, contact a

conductive part of the housing with the probe, which is connected to the protective conductor.

During measurement, the connector cable must only be moved in as far as it is 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.

Sequence

Measurement of Insulation Resistance (equivalent leakage current)

This test is performed with a maximum voltage of 500 V, with a current limit having been set (I < 3.5 mA). However, contacting the terminals (3 or 2) causes an electric shock which, in turn, may result in accidents.

All switches at the device under test must be set to the ON position during measurement of insulation resistance. This also applies to temperature controlled switches and temperature regulators. Measurement must be performed in all program stages for devices equipped with program controllers.

R-INS

Start measurement.

Nominal voltage is 500 V DC in this case.

Nominal voltage can be adjusted within a range of 50 V to 550 V DC.

When insulation is first started from the menu, nominal voltage is always set to 500 V. Open-circuit voltage is always greater than nominal voltage.

General

The equivalent leakage current measurement is a method for measuring protective conductor current (DIN VDE 0701-0702) and/or device leakage current (IEC 62353 (VDE 0751)).

A high-impedance power supply is connected between the short-circuited mains terminals and all exposed metal parts of the housing (which are connected to one another).

Measurement of Equivalent Leakage Current I

per DIN VDE 0701-0702

A high-impedance power supply is connected between each patient port and all exposed metal parts of the housing (which are connected to one another). The mains terminals are short-circuited, and connected to the same point on the housing.

Measurement

The current which flows over the insulation at the device under test is measured separately for each application part.

Measurement is always performed with an AC power supply with current limiting. Varying line voltages are taken into account.

Current is measured between the probe, with which the L and N conductors must be contacted, and the protective conductor terminal PE at the device under test for permanently installed safety class I devices under test.

Disconnect mains power before connecting the test instrument!

õ Remove the mains fuses from the device under test and disconnect

the neutral conductor N inside the device under test.

õ Connect the probe to phase conductor L and neutral conductor N at

the device under test in order to measure equivalent leakage current.

Sequence

Current is displayed during this type of equivalent leakage current measurement which would flow during leakage current measurement conducted in accordance with device regulations with nominal voltage. Leakage current measurement in accordance with the respective device regulations is usually not possible, because the device would have to be set up in an electrically isolated fashion, or connected to an earth isolated power supply to this end.

For the evaluation of measured values during equivalent leakage current measurement please refer to chapter 21.2.

10.3 High-Voltage Test (Feature F02 or SECULIFE ST HV)

Caution: High-Voltage!

Attention!

Only safety class I and II devices can be tested, which can be connected to the test socket.

The high-voltage test is performed with direct voltage. In order to comply with requirements for alternating voltage, testing is performed with 1.5fold direct voltage. This multiplier is applied automatically during testing. A selected nominal voltage of 3.5 kV thus results in a DC output voltage of

5.25 kV.

Output voltage is measured for the entire duration of the test, and its minimum value is determined. The minimum voltage value is indicated as the test result. If this value is less than the pre-selected test voltage, the test is failed.

The conversion factor must be taken into consideration for testing and calibration of the SECULIFE ST

HV.

The device is designed such that special measures in accordance with DIN VDE 0104 (high-voltage test) need not be observed.

This is accomplished by means of the following characteristics:

1. Continuous short-circuit current is less than 3 mA (DC).

2. Discharge energy (at 5.25 kV) is less than 350 mJ.

In order to comply with high-voltage test regulations despite the minimal continuous short-circuit current, the charging capacitors are connected to the test socket (L, N) with relatively low-value protective resistors. This results in a peak short-circuit current value of approximately 5 A (at 5 kV), which causes plainly audible and visible sparking.

High-voltage testing can only be performed via the test socket. The protective conductor at the socket is grounded during the high-voltage test.

To uc h neither the test socket nor the device under test during voltage testing! A high-voltage of up to 5.5 kV is present at the test socket output! A current may flow over your body, and although it does not reach life endangering levels, the resulting shock is plainly discernible. Previous testing of the protective conductor is absolutely essential for safety class I devices because if the protective conductor is in-

terrupted, the high-voltage test does not charge all dielectric material and the scope of testing is thus insufficient.

Connection

õ Insert the mains plug from the device under test into the test socket.

õ Safety class II: Connect the probe to jacks 4 and 5.

Make sure that the application parts (18) are not connected during high-voltage testing!

Individual Test

õ Set the rotary selector switch to the Iso/HV position.

õ Select the U-HV menu with the key and acknowledge with the

key.

õ If the device under test has not yet been switched on, a message to

this effect appears at the display. Nominal voltage is then selected.

õ Select the desired nominal voltage

from the display with the key. The instrument multiplies this nominal voltage by a factor of 1.5, which represents the actual test voltage (see chapter 10.3). Note: For SC I, the test voltage can be set to maximum 1.5 kV.

õ Enter the desired AC nominal voltages for safety classes I and II. The

instrument multiplies the respective AC nominal voltage by a factor of

12.2 Alternating / Direct Voltage U

– Max. 253 V

AC/DC

Direct, alternating and pulsating voltages of up to 253 V can be measured between the 2 and 3 connector jacks.

Furthermore, it is possible to switch between minimum, maximum and momentary measured value via key . This is particularly useful in combination with the SECULOAD test adapter for weld- ing equipment (article number Z745V).

Two procedures are to be distinguished as from firmware version 7.24:

12.1 Probe Voltage U

Voltage is measured between the mains PE terminal at the test instrument and the probe. In this case the probe can also be used as a phase finder. For IEC 61010: A selection can be made with the up scroll key as to whether testing will be conducted under normal conditions, or with interrupted protective conductor.

For conducting the measurement the DUT must be put into service via key (14).

P: potential lead for 4-wire measurement

The potential lead must be connected to the outgoing protective conductor at the distributor.

Cable resistance is measured from the device under test to the test instrument without potential lead P. This value may deviate significantly from actual protective conductor resistance, because the lead is measured along with the test instrument installation. Resistance from the probe terminal to contact P at the protective conductor is measured with the potential lead.

14 Function Test

Attention!

Note

Attention!

Function Tes t

The device under test can be subjected to a function test with line voltage via the integrated test socket.

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 safety class III devices).

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

Each time line voltage is applied to the test socket, phase conductor L and neutral conductor N are reversed, assuming that “polarity reversal = X” is selected in the I leakage switch setting.

The function test is only possible if the device under test has been connected to the test socket (21).

Measurements

The function test includes the following measurements:

–Voltage U – Residual current I

between the L and N conductors

(corresponds to fault current between L and N) – Load current I – Active power P

– Apparent power AP (calculated) – Power factor PF (cos calculated, display > 10 W) – Electrical energy W – On-time t for U

at socket (21)

The following values are also displayed in all test sequences in switch position AUTO after the function test has been completed:

– Maximum residual current I – Maximum load current I – Maximum active power P

max

Lmax

max

Power factor is calculated from active power and apparent power. Power factor corresponds to cos for sinusoidal quantities (line voltage and load current).

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 device under test 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, devices under test must be turned off with their own switch – especially devices with relatively high inductivity.

34 GMC-I Messtechnik GmbH

Page 35

Short-Circuit Test

Note

1 Test for shorts between N and L. 2 Test to determine whether or not

the N or L conductors are shortcircuited to the protective conductor.

A short-circuit at the device under test is recognized automatically by the test instrument. A message appears at the display (9), and the function test is disabled.

If the lamp blinks (15), line voltage can be switched to the test socket with the key (14), and the measurement can be started. If the lamp (15) is lit continuously, line voltage is present at the test socket.

The test socket can be rendered voltage-free with the key (14), or the

function test can be ended with the key (12).

15.1 Test Sequences

Test sequences for the various standards are always run in the same order, assuming that the device under test has been properly connected and the mains connection test has been passed. The test sequence can be run step by step with manual activation of each subsequent step if this function has been specified, or automatically. Step by step manual operation can be selected in the initial program window in the setup menu under “Sequence” ... “manual sequence”.

• Safety class: SC I or SC II is automatically recognized by the test instru-

ment. If the safety class is not correctly recognized, you can change it manually. This manual correction is not stored however.

15.2 Setting Up Test Sequences

The order of a test sequence cannot be changed! However, it is possible to change limit values and measuring parameters, and test steps can be added or skipped.

Principally, two test sequences are distinguished which are described on the following page:

• Sequence 1 (repair tests and periodic tests)

• Sequence 2 (type tests)

Settings for the Test Sequence

Settings for the test sequence are not stored under a type designation, but apply generally for the preset sequence of the respective test standard.

Type-related Settings (Type*) (for tests per EN 60950, EN 61 010 and EN 60 335 only)

The type-related settings only include limit values. These limit values can be stored for each type under an individual type designation. Measurements the limit values of which have been deleted are skipped.

A type can be stored as default type. This type is indicated if the rotary switch is set to Auto.

If no default type has been stored, the following appears for type in the Auto rotary switch position: GENERAL and the general limit values of the se- lected test standard apply.

15.5 Testing Devices in Accordance with DIN VDE 0701, part 240

Attention!

You can either change over to testing in accordance with the new VDE 0701-0702 standard or perform the following measurements in accordance with the above-mentioned standard:

Testing safety class I and II data processing equipment and office machines as individual devices and in combination with one another.

The following measurements can be performed in accordance with the above mentioned standard:

• Protective conductor R Test current: DC ±200 mA

• Housing leakage current I

• According to DIN VDE 0701, part 240, the device protective conductor must be tested after maintenance, repair or modification of data processing equipment and office machines, and exposed, conductive parts must be tested for the absence of voltage. This applies to:

• Safety class I devices for all exposed, conductive parts which are accessible to the user, and which are not connected to the protective conductor

• Safety class II devices (totally insulated devices) for all exposed, conductive parts which are accessible to the user

with the mains plug poled in both directions.

Setting Up the Test Sequence

See chapter 15.4 regarding the test sequence.

Special Parameters

Combined Testing

Safety class I and II devices can be tested individually or in combination. All protective conductor connections are tested first for interconnected safety class I devices, and then – as is also the case for interconnected safety class II devices – all exposed, conductive parts.

Connecting the Device Under Test

õ Connect the test instrument and the DUT as described below:

– Connect both devices to separate mains outlets.

The outlets to which the test instrument and the safety class I DUT are connected must share a common protective conductor!

– Or connect the test instrument to the mains and the DUT to the test

socket at the test instrument.

(permanent connection or with plug)

Data Processing / Office Machines

Permanently connected or with plug

To test socket at the instrument

The requirement for testing with the mains plug poled in both directions can be fulfilled

by connecting the DUT to the test socket at the instrument, and by activating mains polarity reversal in the setup menu under “Sequence”. Each time the key (14) is activated, phase conductor L and neutral conductor N are reversed at the test socket.

Testing with mains polarity reversal or with the mains plug poled in both directions results in interruption of supply power to the affected data processing equipment or office machine. This test may thus only be conducted with the consent of the operator of the data processing equipment or office machine. If the DUT is defective, the electrical system’s RCCB may be tripped during testing which would also result in interruption of supply power to the affected equipment or office machine. The manufacturer of the test instrument assumes no liability for the loss of data or other damage which result from use of the test instrument.

Extension Cables up to 5 m Long

Protective conductor resistance between the earthing contact at the mains plug and all exposed metal parts may not exceed 0.3 for protection class I devices. This value may not exceed 1  for permanently con-

nected data processing systems (DIN VDE 0701, part 240).

Extension and Connector Cables Longer than 5 m

An additional cable resistance of 0.1 , however, not more than 1 , is allowable as of a length of 5 m for each additional 7.5 m.

Resistance testing for cables longer than 5 m is thus advisable (see also limit values on page 20.

The EL1 accessory adapter is required for testing for shortcircuiting and interruption of single-phase extension cables.

16 Storing in (P)SI Module (Accessory) and Database Operations

(Feature KB01)

16.1 Storing Measurement Data in the (P)SI Module

Upon completion of a measurement – message „Test passed/failed“ is displayed – you can file the measurement data in the memory of the (P)SI module.

õ Press the STORE key at the (P)SI module.

A text entry field is displayed.

õ You may now enter your comments on the measurement

and/or an ident. no.

õ Press the STORE key once more in order to save the measurement data

and your comments. The message: „Data are being stored“ is shown on the display.

A detailed description is included in the operating instructions for your (P)SI module in the chapter „Display, print and store protocol“.

16.2 Database Operations

16.2.1 Storing Test Results to the Test Instrument

If no (P)SI module has been connected, up to 125 reports can be stored to the test instrument (without function test values and without comments on DUT). The reports can be viewed as required at the instrument and can be printed out, for example with the help of a terminal program, see chapter 18.

The reports are sorted by time and date and are displayed with the ID number. If no ID number was assigned, date and time are automatically saved instead.

As an alternative, consecutive numbering can be selected.

16.2.2 Uploading Report Templates into Test Instrument, Reading Out From the

Test Instrument, Editing at the PC and Re-Saving to the Test Instrument

The „Test result“ menu allows for storage of up to 4 report templates in the test instrument. Report templates are uploaded from a file at a PC to the test instrument (“Load file”). Templates can also be uploaded from the test instrument to a PC (“Templates from Secutest”), and then edited and resaved.

After completion of a test (“Passed” or “Failed” appears at the instrument’s LCD), the test results are read out to one of these report templates

in the form of report data (depending upon the selector switch position or test regulation) via the RS 232 interface. The report menu in the test instrument is activated with the and keys to this end. In order to read out the report data at a PC, it is necessary to connect the SECUSTORE stor- age adapter with the RS232 interface. The report can, for example, be displayed with the PC analysis program WinProfi (as from version 3.06) or ETC (as from version 1.22).

16.2.3Reading Out and Saving Test Results / Test Data from the (P)SI Module

Test results saved to the test instrument can be displayed, edited, printed (only PSI module) or saved after reading them into a PC using the desired report template.

Data can be processed immediately after completion of the test, or from the database (Feature KB01). Data can be saved with or without a report template (e.g. for further processing with PS3).

Test results saved to the (P)SI module can also be read out, printed (only PSI module), saved or processed by means of a report template.

Easy method of printing out reports: Activate the „test result“ menu in the update and options installation pro-

gram. When the test result is displayed in the test instrument select the print function (press key „Cursor up“, then set the cursor on „print“ and press ENTER).

17 Recognition of Probe to Protective Conductor

(Feature KD01)

The protective conductor measurement is expanded to include the function: “automatic recognition of measuring point change”. During protective conductor measurement, the instrument recognizes whether or not the probe is in contact with the protective conductor, and indicates these two possible conditions by means of acoustic signals.

This function is helpful if several protective conductor connections need to be tested. The function can be activated in the “test sequence setup” menu with “auto measuring point” (see “changes to the switch position menu” above).

58 GMC-I Messtechnik GmbH

Page 59

18 Storing Test Results and Printing in Report Form

(read out)

You can shift to the Protocol menu from any of the displayed test results (1 page) with the help of the key.

Storing to the Test Instrument

Measurement results for the current test can be stored to the test instrument, the results of the current test can be printed out to the corresponding report form, previously stored test results can be queried (scroll: Feature KB01, see chapter 16) and all stored measurement results can be read out from this menu.

The report template automatically complies with the standard of the selected switch position, provided that parameter „Select template“ has been deactivated.

If parameter „Select template“ is activated, it is possible to select one of 5 different report templates. Templates 1 to 4 can be modified via the update and options installation program SECU-Up, see chapter 16.2.2.

Direct Print-Out (Feature KE01 in Combination with a PSI Module or SECUSTORE Storage Adapter)

After completion of each test (individual test or at the end of a test sequence), test results are read out directly via the RS232 interface.

When the PSI module is connected (accessory, not part of the standard equipment), the result is directly printed on paper. When the SECUSTORE storage adapter is connected, the test result is stored to memory.

Storing to the SECUSTORE Storage Adapter (Accessory)

Connect the SECUSTORE storage adapter with the test instrument via the RS232 interface. The (P)SI module may not be connected.

21 Appendix

21.1 Evaluation of Measured Values for Individual Measurements as well as for Calculated Quantities

In order to assure that the limit values for the individual measurements are always observed, device measuring error must be taken into consideration. The table in the appendix allows for calculation of the required minimum display value for each respective measurement which must appear at the instrument in consideration of measuring error (under nominal conditions of use), in order to assure that the required limit value is not fallen short of (DIN VDE 0413, part 1). Intermediate values can be interpolated.

Measuring Error for Test Sequences

The test instrument takes respective measuring error into consideration during automatic test sequences, and corrected results are entered into the test report, as long as this function has been activated in the setup menu under “include service error”.

Omitting the Protective Conductor Test in the Case of Fully Insulated Devices

You are testing a fully insulated safety class I device (e. g. screen, submersible pump, etc.), which is not equipped with an external protective conductor contact.

The decision as to the necessity of a protective conductor test in this case is to be taken by a qualified electrician who should also assume responsibility.

You can omit the protective conductor test by pressing the key as soon as the following instruction is shown: „Please connect the probe with the protective conductor of the DUT“.

21.2 Evaluation of Measured Values during Equivalent Leakage Current Measurement (Automatic Test Sequence According to Standard)

During equivalent leakage current measurement, L and N are interconnected whereupon a test voltage of 230 V is applied between LN and PE and the leakage current is measured. Thus the most adverse case (N interrupted) is being tested.

As a rule, this results in at least double the value of the direct leakage current measurement (since all discharge capacitors are placed in parallel).

If frequency converters are used in addition to that, it is no longer possible to compare the measured values between direct leakage current and equivalent leakage current method. In this case, we recommend conducting individual measurements in accordance with the residual current method.

22 Maintenance - Recalibration

22.1 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 or solvents.

22.2 Recalibration

The respective measuring task and the stress to which your measuring instrument is subjected affect the ageing of the components and may result in deviations from the guaranteed accuracy.

If high measuring accuracy is required and the instrument is frequently used in field applications, combined with transport stress and great temperature fluctuations, we recommend a relatively short calibration interval of 1 year. If your measuring instrument is mainly used in the laboratory and indoors without being exposed to any major climatic or mechanical stress, a calibration interval of 2-3 years is usually sufficient.

During recalibration* in an accredited calibration laboratory (DIN EN ISO/IEC 17025) the deviations of your instrument in relation to traceable standards are measured and documented. The deviations determined in the process are used for correction of the readings during subsequent application.

We are pleased to perform DKD or factory calibrations for you in our calibration laboratory. Please visit our website at www.gossenmetrawatt.com ( Services  DKD Calibration Center or  FAQs  Calibration questions and answers).

By having your measuring instrument calibrated regularly, you fulfill the requirements of a quality management system per DIN EN ISO 9001.

Standards DIN VDE 0701-0702 and IEC 63353 (VDE 0751) stipulate that only measuring instruments which are regularly tested and calibrated may be used for testing.

22.3 Safety Checks

Check the safety of your test instrument on a regular basis. We recommend the same test intervals as for recalibration.

The SECUTEST... is designed as a totally insulated instrument in accordance with standards IEC 61010 and VDE 0404. The protective conductor is only used for measurement purposes and is therefore not accessible in idle state. A protective conductor test at the test socket can be performed as follows:

Ð Connect the SECUTEST... to a multiple distribution box.

Ð Conduct a contact current measurement for permanently installed

DUTs (the test socket may not be connected to any load).

Ð Measure the protective conductor resistance between the neighbour-

ing socket of the multiple distribution box and the test socket.

Ð The measured value may not exceed 0.3 .

Insulation resistance between LN and PE in the SECUTEST... equals approx. 150 kfor metrological reasons. This must be taken into account when performing the safety checks, i.e. the protective conductor current measurement must produce a value below 3.5 mA, instead of insulation resistance measurement (if the equivalent leakage current measurement method has been chosen, the value must remain below 7 mA).

Apart from this, the SECUTEST... features 3 exposed conductive parts for which contact current measurement must produce a value below 0.5 mA:

• RS232 interface

• metallized start key

• protective conductor clip at the test socket.

* Verification of specifications or adjustment services are not part of the calibration.

For products from our factory, however, any necessary adjustment is frequently performed and the observance of the relevant specification is confirmed.
