SECULIFE ST PRO Safety Precautions

1 Safety Precautions

SECUTEST BASE(10), SECUTEST PRO and SECULIFE ST BASE(25) test instruments are
manufactured and tested in accordance with the following safety regulations: IEC/EN 61010-1 / VDE 0411-1, DIN VDE 0404, IEC/EN 61577 / VDE 0413-2,-4 / DIN EN 61557-16 / VDE 0413-16
The safety of the user, the test instrument and the device under test (electrical equip­ment or electrical medical device) is only assured when the instrument is used for its intended purpose.
Read these condensed operating instructions and the full operating instructions carefully and com­pletely before placing your test instrument into service (available at our homepage www.gossen­metrawatt.com for download). 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 any active or passive implanted medical devices, please consult your doctor or the manufacturer of these devices.
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 (TN, TT or IT) with a maximum of 240 V which complies with applicable safety regulations (e.g. IEC 60346, VDE 0100) and is protected with a fuse or circuit breaker with a maximum rating of 16 A.
• Measurements within electrical systems are prohibited.
Be prepared for the occurrence of unex­pected voltages at devices under test (for example, capacitors can be dangerously charged).
• Make certain that the measurement cables are in flawless condition, e.g. no damage to insulation, no cracks in cables or plugs etc.
• When using a test probe with coil cord (SK2W): Grip the tip of the test probe firmly, for example during insertion into a jack socket. Tensioning at the coil cord may otherwise cause the test probe to snap back resulting in possible injury.
Measurement of insulation resistance and
equivalent leakage current (leakage current alternative measuring methods)
Testing is conducted with up to 500 V. Current limiting is utilized (I < 3.5 mA), but if terminals L or N at the test socket are touched, electrical shock may occur which could result in consequential acci­dents.
Leakage current measurement during opera- tion with line voltage: Please note that the device under test is operated with line voltage during measurement. Exposed conductive parts may conduct danger­ous touch voltage during testing. Do not touch under any circumstances! (Mains power is disconnected if leakage current exceeds approx. 10 mA.)
The function test may only be per­formed after the DUT has successfully passed the safety test!
Probe check for probe connector P1: Please perform a probe check after each test.
If there is a fuse defect in test probe P1 after having started the test, all subsequent measurements which are performed with this measure­ment path might be erroneously rated as good!

SECULIFE ST PRO Safety Precautions
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.
Any warranty claims will be forfeited when the warranty seal has been damaged or removed.
Switching power consumers (max. 16 A*)
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.
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 a non-authorized/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 serious damage due to transport
In such cases, the instrument must be removed from operation and secured against unintentional use.

SECULIFE ST PRO Initial Start-Up

2 Initial Start-Up

2.1 Mains Connection

Nominal mains values: 100 to 240 V, 50 Hz to 400 Hz
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 (see wiring diagram in the operating instructions).
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.
Measurements in IT Systems (as from FW 1.5.0)
The setting IT system can be activated in selector switch position SETUP (Setup 1/3) under sub-menu All Measurement:
Parameter „Meas. at IT-mains“ = Yes: active leakage current measurements (and/or all measurements which include the PE at the mains connection end) are blocked. Test sequences which contain such kind of mea­surements are disabled as well.

2.2 Detection of Mains Connection Errors

The device automatically recognizes mains connection errors if the conditions in the fol­lowing table have been fulfilled. The user is informed of the type of error, and all measuring functions are disabled in the event of danger.

5 Internal Database

5.1 Creation of Test Structures

A complete test structure with data regard­ing customers and devices under test be created in the test instrument. This structure makes it possible to store the results of sin­gle measurements or test sequences of test objects belonging to various customers. Manual single measurements can be grouped together into a so-called „manual sequence“. base creation is included in the full operating instructions for your test instrument.
5.2 Export – Transmission and Storage of
Structures set up in, and measurement data saved to the test instrument can be imported to the IZYTRONIQ report generating software via a plugged-in USB stick (PRO and/or Fea­ture KB01 only) or via the USB slave port. Data can then be saved to the PC and reports can be generated.
Furthermore, you can save the database to a plugged-in USB stick for subsequent restoring to the device memory.

5.3 Import

The test structures created at the PC with the help of the report generating software can be loaded into the test instrument via an USB stick or via the USB slave port.

SECULIFE ST PRO Single Measurements

8 Single Measurements

Any measuring duration is possible. The respective measurement is ended by press­ing START/STOP. No limit values have been entered for single measurements. As a result, no evaluation of the measurement results takes place.
Procedure for measuring with save function and pre-selection of the (ME) device
If you’d like to save your single measure­ments to selected (ME) devices in a data­base (see section 5), the following procedure is advisable.
1 Activate the database view (MEM
navigation) by pressing the MEM key.
2 Select the (ME) device or its ID num-
ber for the following measurements with the scroll keys.
3 Return to the measuring view by
pressing the ESC key or the START/
STOP key.
4 Start the test with the START/STOP
key before switching the DUT on. The measured value recording symbol shown at the right appears. Each time this key is pressed, the currently displayed value is saved to the clipboard and the number shown in the symbol is increased by one.
5 Switch off the DUT before finish-
ing the test with the START/STOP key. The Save as symbol appears (floppy disk icon with the number of measured values saved to the clipboard).
6 If you press the save symbol now,
the display is switched to the SAVE view, where the pre-selected (ME) device is highlighted.
7 After pressing the Save symbol
once again, acknowledgement of successful storage appears. At the same time, the display returns to the measuring view.
Procedure for measuring with save function and
subsequent entry of the (ME) device
As an alternative to the procedure described
above, you can start with step 4 and, after
measurement has been completed, assign
the results to a (ME) device or its ID number
which is included in the database: manually
by selecting ID and entering the ID via the
alphanumeric keyboard, or by scanning a
barcode.
