SECUTEST ST BASE(10) / PRO und SECULIFE ST BASE(25)

1 Safety Precautions

SECUTEST ST BASE(10), SECUTEST ST 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 “automatic test sequences” are semi-

automatically controlled sequences whose

progress is interrupted by safety-relevant

stoppages and the associated warnings and

instructions. As a result, the level of protec-

tion provided to the user is greater than

demanded by sections 4.1.6 and 4.1.7 of

DIN EN 61557-16 with regard to “automatic

test sequences”.

The safety of the user, the test instrument

and the device under test (electrical equip-

ment 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 (avail-

able 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.

Note

Manufacturers and importers of electrical

medical devices must provide documen-

tation for the performance of mainte-

nance by trained personnel.

Observe the following safety precautions:

• The instrument may only be connected to

electrical systems (TN, TT or IT) with a maxi-

mum of 240 V which complies with applica-

ble 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 unex-

pected voltages at devices under test

(for example, capacitors can be danger-

ously 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. Cur-

rent 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.

•During operation with line voltage:

Exposed conductive parts may conduct

dangerous touch voltage during testing.

Do not touch under any circumstances!

Use a special cover in order to avoid

touch contact.

Mains power is disconnected at the

instrument if leakage current exceeds

approx. 10 mA (can be switched to 30

mA). However, this does not fulfill the

requirements specified for a PRCD. If the

“Proceed in case of limit violation” setting

is used, enhanced safeguarding against

touch contact and a 30 mA RCD must

be used, and personal protective equip-

ment (PPE) must be worn (secure work-

station).

Gossen Metrawatt GmbH 5

SECUTEST ST BASE(10) / PRO und SECULIFE ST BASE(25)

Attention!

The function test may only be per-

formed after the DUT has successfully

passed the safety test!

•Probe check for probe connector P1: Please

perform a probe check after each test.

Attention!

If there is a fuse defect in test probe

P1 after having started the test, all

subsequent measurements which

are performed with this measure-

ment path might be erroneously

rated 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 mea-

suring 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 person-

nel, no guarantee claims can be honored by

the manufacturer with regard to personal

safety, measuring accuracy, compliance

with applicable safety measures or any con-

sequential 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.

Before measurement:

1) DUT: Turn the DUT off via its own switch.

2) Tester:

Switch line voltage to the test

socket.

3) DUT: Turn the DUT on via its own switch.

After measurement:

4) DUT: Turn the DUT off via its own switch.

5) Tester:

Deactivate line voltage to the test

socket.

* for currents > 16 A AC please use adapter

AT3-IIS32 (Z745X), for example

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 dan-

gerous 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 manipu-

lation carried out by a non-authorized/non-

certified service provider.

• With damaged connection and/or mea-

surement 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.

3 Initial Start-Up

3.1 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).

Attention!

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 ac-

cordance with the diagram. Discon-

nection from mains power is only

possible with the mains plug.

Measurements in IT Systems

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 mea-

surements are disabled as well.

3.2 Detection of Mains Connection Errors

The device automatically recognizes mains

connection errors if the conditions in the fol-

lowing table have been fulfilled. The user is

informed of the type of error, and all measur-

ing functions are disabled in the event of

danger.

10 A/25 A R

measurements are only possible with line

voltages of 115/230 V and line frequencies of 50/60 Hz.

if the test person is highly insulated, the following error

message may appear: „Interference voltage at PE of

mains connection“

Attention!

In the event of mains connection er-

rors as described in either of the first

two cases in the table above, imme-

diately disconnect the test instrument

from the mains and arrange to have

the error eliminated!

Note
