Operating Conditions; Warranty And Repair - Hameg HM6050-2 Benutzerhandbuch

I m p o r t a n t h i n t s
all parts of the housing and the chassis are con-
nected to the safety ground terminal of the power
connector. For safety reasons the instrument
must only be operated from 3 terminal power
connectors or via isolation transformers. In case
of doubt the power connector should be checked
according to DIN VDE 0100/610.
Do not disconnect the safety ground
either inside or outside of the instru-
ment!
Attention!All interface lines are galva-
nic coupled to the LISN.
As mentioned in paragraph "Safety" the LISN has
to be operated on athree line mains outlet (with
protective ground line). An interface cablebetween
the RS-232 interface of the LISN and the COM port
of a PCcauses a galvanic connection between the
two devices. To excludenegative effects on other
safety provisions the PC's power cable mustbe
connected to the same mains outlet as the LISN.
Disregarding these safety hints (also
see "Safety") will result inthe loss of
HAMEG's warranty in case of dama-
ges. HAMEG isnot liable for any inju-
ries to personnel or any equipment.
Opening of the instrument is only allowed to qua-
lified personnel Prior to opening, the instrument
must be disconnected from the line voltage and
all other inputs/outputs.
In any of the following cases the instrument must
be taken out of service and locked away from
unauthorized use.
This may occur:
– if the instrument shows visible damage,
– if the instrument has loose parts.
– if the instrument does not function,
– after long storage under unfavourable
circumstances (e.g. outdoors or in moist
environments),
– after excessive transportation stress (e.g. in
poor packaging).

Subject to change without notice
to the regulations as defined in VDE 0876
Part1("Measurement of radiated emissions"). It
conforms to the regulationsas defined in CISPR
Publ.16 or. EN55011.
The ambient temperature range during operation
should be between +5 °C and +40 °C and should
not exceed –20 °C or +70 °C during transport or
storage. The operational position is optional, ho-
wever, the ventilation holes on the HM8001-2 and
on the plug-in modules must not be obstructed.
In principle the instrument may be used in any
position, however sufficient ventilation must be
ensured. Operation for extended periods of time
requires the horizontal or tilted (handle) position.
Nominal specifications are valid after 30 minutes
warm-up at 23 deg. C. Specifications without
tolerances are typical values taken of average
production units.

Warranty and Repair

Our instruments are subject to strict quality con-
trols. Prior to leaving the manufacturing site, each
instrument undergoes a 10-hour burn-in test. This
is followed by extensive functional quality testing
to examine all operating modes and to guarantee
compliance with the specified technical data. The
testing is performed with testing equipment that
is calibrated to national standards. The statutory
warranty provisions shall be governed by the laws
of the country in which the product was purchased.
In case of any complaints, please contact your
supplier.
The product may only be opened by
authorized and qualified personnel.
Prior to working on the product or
before the product is opened, it must
be disconnected from the AC supply
network. Otherwise, personnel will
be exposed to the risk of an electric
shock.
Any adjustments, replacements of parts, main-
tenance and repair may be carried out only by
authorized technical personnel. Only original
parts may be used for replacing parts relevant to
safety (e.g. power switches, power transformers,
fuses). A safety test must always be performed
after parts relevant to safety have been replaced
