socket. Tensioning at the coil cord may otherwise cause the test probe to snap back resulting in possible injury.

The test is conducted with up to 500 V, with a current limit of I < 10 mA. However, when touching the terminals (L or N), you will get an electric shock which, in turn, may lead to accidents. Feature F01: When connecting the DUT via jacks 1 to 3, special care must be taken to avoid touching the open cables.

• Leakage current measurement During leakage current measurement it is essential to ensure that the DUT is operated at mains voltage. Exposed conductive parts may be subject to hazardous contact voltage during the test and may not be touched under any cricumstances. (A mains shutdown takes place when the leakage current exceeds approx. 10 mA).

Attention!

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

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.

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.

Safety Class II Devices

These devices are equipped with double insulation or reinforced insulation.

Safety Class III Devices

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.

Note: The DUT may only be connected to the test instrument at jacks 1 through 3 (Feature F01). Only a visual inspection, an insulation resistance measurement or a measurement of the supply voltage can be performed, see parameter “SC II I U

” on page 27.

The test is failed by a DUT with 300 kW with deactivated classification function (= _), but it is passed with activated classification function (= x) if the question is answered accordingly.

Similar possibilities for passing the test, although it might otherwise be failed, are included in DIN VDE 0701, part 1.

If the DUT is connected via the jacks instead of the test socket, other limit values apply because higher power consumption is possible in this case (e.g. part 1 specifies a limit value of 1 mA per kW for equivalent leakage current).

See also table: “Maximum Allowable Limit Values for Equivalent

Leakage Current in mA” on page 20.

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 or II.

Parameter Classification (in the Sequence... menu)

The SECUTEST ues of the respectively selected safety class. The test is failed if this limit value is exceeded. However, devices under test exist for which higher limit values are allowable.

If parameter classification is activated (= x), the user is asked if higher limit values are allowable for the DUT. If “Yes” is entered, reevaluation ensues and the DUT may pass the test.

Examples

If the insulation resistance test is failed, or if interference suppression capacitors have been replaced, equivalent leakage current measurement must be performed on DUTs with heating elements in accordance with DIN VDE 0702.

9 Individual Measurements

9.1 Measuring Protective Conductor Resistance

Definition

Protective conductor resistance is the sum of the following resistances:

• Connector cable or device connector cable resistance

• Contact resistance at plug and terminal connections

• Extension cable resistance if utilized

Resistance is measured:

• Between each exposed conductive part of the housing and the earthing contacts at the mains and the device plug (if a removable mains connector cable is used), or the protective conductor terminal for permanently installed devices.

• As a 4-pole measurement

• Between the earthing contacts at the mains plug and the earthing contacts at the device plug for device connector cables

• Between the earthing contacts at the mains plug and the earthing contacts at the coupling socket for extension cables

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).

➭ 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 to the extent 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.

Testing Extension Cables

Combined Test – Differential Protective Conductor Resistance Zero balancing is also possible for protective conductor measurement. With

zero balancing, all subsequent measurements are adjusted with an offset such that 0 Ω is displayed for a selected reference point which is connected to the protective conductor. When test points are contacted with the probe which are electrically connected to this reference point, differential resistance ΔR test point is displayed.

10 Function Test

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

Function Test

In addition to testing with the selector switch in the function test position, or with the Function parameter in the MENU position (feature F01 only), 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).

Attention!

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

☞

Note

Each time line voltage is applied to the test socket, phase conductor L and neutral conductor N are automatically reversed, if the “mains polarity reversal” function has been activated (= x) in the I leakage selector switch position.

Note

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-LN between the L and N conductors – Residual current ΔI

(corresponds to fault current between L and N) – Load current I – Active power P – Apparent power S (calculated) – Power factor PF (cos ϕ calculated, display > 10 W) – Electrical energy W – On-time t for U

The following values are also displayed for all selector switch positions except MENU, after the function test has been completed:

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

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

Attention! 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.

• 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

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

➭ 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 under “Sequence” in the setup menu. Each time the key (14) is activated, phase conductor L and neutral conductor N are reversed at the test socket.

Attention!

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.

11.7 Testing Extension Cables for VDE 0701, Part 1, and VDE 0702

(option: EL1 adapter)

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 Ω for safety class I devices. This value may not exceed 1 Ω for permanently connected data processing systems (DIN VDE 0701, part 240).

Extension and Connector Cables Longer than 5 m

Per DIN VDE 0702, an additional cable resistance of 0.1 Ω, however, not more than 1 Ω, 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 17).

and Database Operations (Feature KB01 or DBmed option)

12.1 Storing Measurement Data in the PSI Module

Upon completion of a measurement – „Test passed/Test failed“ is shown on the display – you can save the measurement data to the memory of the PSI module.

➭ Press the STORE key at the PSI module to this end.

A text entry field is shown.

➭ You may now enter your comments on the measurement and/or an

identification number.

➭ Press the STORE key once more to save the measurement data and

your comments. The message: „Data are stored“ is displayed.

A detailed description is given in the operating instructions of your PSI module under chapter „How to display, print and store protcol“.

12.2 Database Operations

12.2.1 Setting Up Test Sequences with PC Software

This function must be activated with the help of upgrade software, e.g. the Z853H program.

Up to 99 test sequences can be uploaded for each of the selector switch positions from a PC via the serial port at the SECUTEST ment. After testing has been performed, the test results are saved to the same database, if a PSI module has not been connected. The maximum possible sum of test sequences and test results is 127.

Test results are stored to the PSI module if one has been connected. The database can be used in different ways:

(see also chapter 11.2 on page 27)

1. Stored test results can be displayed

(select the ID no. and then activate the “from database” function). The desired test sequence can be selected with the scroll keys.

2. If “ID no. = test sequence” has been activated (X), the first two

characters of the ID number determine the test sequence.

12.2.2 Storing Test Results to the SECUTEST

This function must be activated with the help of upgrade software, e.g. the Z853H program.

If no PSI module has been connected, up to 99 reports can be stored to the test instrument. The reports can be viewed as required at the instrument and can be printed out, for example with the help of DA-II software or a terminal program.

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.

Test sequence number 03 is executed. Test sequence 03 is the test sequence which appears at the third position from the top of the list.

Note

The database can only be generated or deleted with the help of a PC with a terminal program, or appropriate application software.

SII

13 Remote Control (Feature KD01 or SK5 Option)

This function must be activated with the help of upgrade software, e.g. the Z745K program.

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 different acoustic signals.

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

14.2 Printing Test Results in Report Form

Test instruments can be connected to commercially available printers with the DA-II printer adapter (Z745M), even if they are not equipped with a parallel port, thus allowing for on-site print-out of test reports etc.

The only prerequisite is that the printer module is set up for direct report generation.

Measurement results for the current test can be stored to memory, the results of the current test can be printed out to the corresponding report form, previously stored test results can be queried (scroll: DBmed option, see chapter 12) and all saved measurement results can be printed out from this menu.

Print-out is executed directly to the Centronics printer via printer adapter DA-II.

The matching report form is automatically selected for the standard selected with the selector switch.

18 Appendix

18.1 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 switch position under “include service error”.
