Please read this important information!

2.1 Intended Use / Use for Intended

Purpose

Safety of the operator, as well as that of the

test instrument, is only assured when it’s

used for its intended purpose.

The SECUTEST ST BASE, the SECUTEST

ST BASE10, the SECUTEST ST PRO, SEC-

ULIFE ST BASE and the SECULIFE ST

BASE25 are test instruments for testing the

electrical protective measures of electrical

devices, electrical medical devices and elec-

tric welding equipment.

All test instruments include measuring and

test functions for checking the effectiveness

of the protective measures required in

accordance with the respective test stan-

dards for the particular field of technology.

Single measurements and test sequences

can be executed.

Test sequences (semi-automatic test proce-

dures) can be used in an integrated, i.e. pre-

configured form, or defined individually by

the user.

The integrated test sequences consist of a

preconfigured series of individual tests with

subsequent documentation, as stipulated in

the respective standard. They can thus be

used to repeatedly and efficiently perform

standards-compliant tests. Their progress is

interrupted by safety-related pauses, as well

as associated warnings and instructions. As

a result, the level of protection provided to

the user is greater than demanded by sec-

tions 4.1.6 and 4.1.7 of standard “IEC /

61557-16 / DIN EN 61557-16 / VDE 0413-

16” with regard to “automated test

sequences”.

The integrated test sequences can be used

to comply with the following standards:

• VDE 0701-0702 / ÖVE E 8701 /

SNR 462638

Inspection after repair, modification of

electrical appliances – Periodic inspec-

tion on electrical appliances

• IEC 62353 / EN 62353 / VDE 0751-1

Attention!

The integrated, preconfigured test

sequences do not include all of the

tests prescribed by the product stan-

dard which are required for type test-

ing! They’re restricted to the tests

which are required as a rule after re-

pair or during maintenance work and

for occupational health and safety

measures, as well as for quality as-

surance in production.

Note

Availability of the individual integrated

test sequences depends on the test

instrument type (SECUTEST ST... or

SECULIFE ST... ...), the selected fea-

tures (order features) and the enabled

extensions (activations).

Refer to your order / test instrument

and data sheet for details.

Associated, database-driven test software is

available, i.e. IZYTRONIQ. This software

facilitates test organization and the manage-

ment of test data from a broad range of test

instruments. It also provides extended func-

tions such as remote control in connection

with the respective test instrument – support

for extended functions depends on the test

instrument and its order features or enabled

extensions (activations). The software itself is

included with test equipment sets, or can be

purchased separately.

The test instrument housing is compact,

impact resistant and includes an integrated

rubber protector for mobile use, e.g. in fac-

tories, on construction sites and in industrial

environments.

The front panels and housings of SECULIFE

ST BASE and SECULIFE ST BASE25 test

instruments are also furnished with antimi-

crobial properties, which make it possible to

use them in hygienically sensitive areas.
