Please read this important information!
2.1 Intended Use / Use for Intended Purpose
Measuring and test instruments from the PROFITEST MASTER
series include:
• PROFITEST MBASE+ (M520S)
• PROFITEST MXTRA (M522P)
• PROFITEST MTECH+ (M522R)
• PROFITEST MPRO (M520N)
The test instruments are used to test the effectiveness of protec-
tive measures at stationary electrical systems in accordance with
IEC 60364-6, EN 50110-1 and other country-specific standards.
They can also be used for the testing of electric charging stations
per EN 61851-1 (DIN VDE 0122-1), and for earth measurements.
The test instruments include pre-programmed test sequences for
increased working convenience and user-defined test sequences
can also be programmed as an option.
The test instruments are especially well suited for testing electrical
systems during setup, initial startup, periodic testing and trouble-
shooting.
The applications range of the test instruments covers all alternat-
ing and 3-phase current systems with nominal voltages of 230/
400 V (300/500 V) and nominal frequencies of 16⅔, 50, 60, 200
and 400 Hz.
A system structure is set up in the test instrument and measured
values are assigned to the objects. Completed tests and mea-
sured values can be saved and documented in a measurement
and test report.
Safety of the operator, as well as that of the test instrument, is
only assured when it’s used for its intended purpose.
2.2 Use for Other than Intended Purpose
Using the test instrument for any purposes other than those
described in these operating instructions, or in the test instru-
ment’s condensed operating instructions, is contrary to use for
intended purpose.
2.3 Liability and Guarantee
Gossen Metrawatt GmbH assumes no liability for property dam-
age, personal injury or consequential damage resulting from
improper or incorrect use of the product, in particular due to fail-
ure to observe the product documentation. Furthermore, all guar-
antee claims are rendered null and void in such cases.
Nor does Gossen Metrawatt GmbH accept any liability for data
loss.
2.4 Opening the Instrument / Repairs
In order to ensure flawless, safe operation and to assure that the
guarantee isn’t rendered null and void, the test instrument may
only be opened by authorized, trained personnel. Even original
replacement parts may only be installed by authorized, trained
personnel.
Unauthorized modification of the test instrument is prohibited.
If it can be ascertained that the test 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.
If the guarantee seal is damaged or removed, all guarantee claims
are rendered null and void.
