2.2 Overview of Features Included
with PROFITEST MASTER & SECULIFE IP Device Variants
1)
The so-called live measurement is only advisable if there is no bias current within
the system. Only suitable for motor circuit breaker with low nominal current

3 Safety Features and Precautions
This instrument fulfills all requirements of applicable European and
national EC directives. We confirm this with the CE mark. The rel-
evant declaration of conformity can be obtained from GMC-I
Messtechnik GmbH.
The electronic measuring and test instrument is manufactured
and tested in accordance with safety regulations IEC 61010-1/
EN 61010-1/VDE 0411-1 and EN 61557.
Safety of the operator, as well as that of the instrument, is only
assured when it is used for its intended purpose.
Read the operating instructions thoroughly and carefully before using
your instrument. Follow all instructions contained therein. Make sure that
the operating instructions are available to all users of the instrument.
Tests may only be executed by a qualified electrician.
Grip and hold the test plug and test probes securely when they
have been inserted, for example, into a socket. Danger of injury
exists if tugging at the coil cord occurs, which may cause the test
plug or test probes to snap back.
The measuring and test instrument may not be placed into service:
• If the battery compartment lid has been removed
• If external damage is apparent
• If connector cable or measuring adapters are damaged
•If the instrument no longer functions flawlessly
• After a long period of storage under unfavorable conditions
(e.g. humidity, dust, temperature)
Exclusion of Liability
When testing systems with RCCBs, the latter may switch off. This may
occur even though the test does not normally provide for it. Leak-
age currents may be present which, in combination with the test
current of the test instrument, exceed the shutdown threshold
value of the RCCB. PCs which are operated in proximity to such
RCCB systems may switch off as a consequence. This may result
in inadvertent loss of data. Before conducting tests, precautions
should therefore be taken to ensure that all data and programs
are adequately saved, and the computer should be switched off if
necessary. The manufacturer of the test instrument assumes no
liability for any direct or indirect damage to equipment, comput-
ers, peripheral equipment or data bases when performing tests.
Opening of Equipment / Repair
The equipment may be opened only by authorized service per-
sonnel to ensure the safe and correct operation of the equipment
and to keep the warranty valid.
Even original spare parts may be installed only by authorized ser-
vice personnel.
In case the equipment was opened by unauthorized personnel,
no warranty regarding personal safety, measurement accuracy,
conformity with applicable safety measures or any consequential
damage is granted by the manufacturer.
Any warranty claims will be forfeited when the warranty seal has
been damaged or removed.
