Safety instructions

Our measurement bridges did leave the factory in
perfect condition. They conform hence to the Euro-
pean standards EN 61010-1 resp. IEC 61010-1. In or-
der to preserve conformity and ensure safe opera-
tion the user is requested to observe the guidelines
and warning hints in this manual, the test and ser-
vice instructions.
Whenever it is suspected that safe operation may
be endangered the bridge should be taken out
of service and protected against unauthorized
operation.
Safe operation may be endangered if any of the fol-
lowing is the case:
❙ The bridge shows visible damage.
❙ Loose parts floating around inside.
❙ The bridge does not function properly.
❙ After prolonged storage under un-favourable
conditions (e.g. in the open or in damp rooms)
❙ Following excessive transport conditions (e.g. the
transport package did not correspond to minimum
requirements by mail, rail or other carriers)

Operating conditions

The permissible operating temperature is +5 °C to
+40 °C. During transport and storage the tempera-
ture may be –20 °C to +70 °C. In case of condensa-
tion after transport it is necessary to dry the bridge
for at least 2 hrs. prior to operation. The bridge is
destined for operation in clean, dry rooms.
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 purcha-
sed. 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 net-
work. Otherwise, personnel will be exposed to
the risk of an electric shock.
Any adjustments, replacements of parts, mainte-
nance and repair may be carried out only by autho-
rized technical personnel. Only original parts may
be used for replacing parts relevant to safety (e.g.
power switches, power transformers, fuses). A sa-
fety test must always be performed after parts re-
levant to safety have been replaced (visual in-
spection, PE conductor test, insulation resistance
measurement, leakage current measurement, func-
tional test). This helps ensure the continued safety
of the product.
