Safety
The instrument has been designed and tested in accordance
with VDE 0411 , safety requirements for electrical equipments
for measurement, control and laboratory use. It has left the
factory wholy conform to this standard. Thus it is also in
accordance with the International standard IEC Publication
1010-1 and the European standard EN 61010-1.
The case chassis and all measuring terminals are connected to
the protective earth contact of the appliance inlet. The
instrument operates according to safety Class I (three-conductor
power cord with protective earthing conductor and a plug with
earthing contact).
CAUTION:
The mains/line plug shall only be inserted in a socket
outlet provided with a protective earth contact. The
protective action must not be negated by the use of an
extension cord without a protective conductor (or
other means).
The mains/line plug should be inserted before connections are
made to measuring circuits. Whenever it is likely that protection
has been impaired, the instrument shall be made inoperative
and be secured against any unintended operation. The
protection is likely to be impaired if, for example, the instrument
· shows visible damage.
· fails to perform the intended measurements.
· has been subjected to prolonged storage under unfavourable
conditions (e.g. in the open or in moist environments).
· has been subject to severe transport stress (e.g. in poor
packaging).
In case of leakage coming from a broken «lcd» display and
contact with skin, clean with pure water and soap . When the
metallic case is open or replaced, the instrument has to be
disconnected from the power. If measurements or calibrations
are necessary with an open instrument, they must be performed
by a qualified technician.
Operating conditions
The instrument has been designed for indoor use. The
permissible ambient temperature range during operation is
+0°C to +40°C, nevertheless refer to the technical specifications
at +23°C 2°C. It may occasionally be subjected to temperatures
-10°C without degrading its safety. The permissible ambient
temperature range for storage or transportation is -40°C to
+60°C.
The maximum operating altitude is up to 2200m. The maximum
relative humidity is up to 80%.
If condensed water exists in the instrument it should be
acclimatized before switching on . In some cases (e.g. extremely
cold) two hours should be allowed before the instrument is put
into operation. The instrument should be kept in a clean and
dry room and must not be operated in explosive, corrosive,
dusty, or moist environments. The instrument can operate in
any position, but the convection cooling must not be impaired
and the ventilation holes must not be covered.

Power requirement
The instrument is designed for a power source of 110V/220V
50Hz. The frequency and the voltage can fluctuate to 10%. An
AC power cord is supplied with the instrument. Connect it to
the power receptacle on the rear panel. Before connecting the
instrument to the power source, always make certain that the
line voltage switches on the rear panel are set to the position
corresponding to the voltage of the AC power source. The
instrument is protected by a slo-blow fuse installed in the fuse
holder.
