Operating conditions

This instrument must be used only by qualifi ed experts who are aware
of the risks of electrical measurement. The instrument is specifi ed
for operation in industry, light industry, commercial and residential
environments.
Due to safety reasons the instrument must only be connected to a
properly installed power outlet, containing a protective earth conductor.
The protective earth connection must not be broken. The power plug
must be inserted in the power outlet while any connection is made to
the test device.
The instrument has been designed for indoor use. The permissible ambi-
ent temperature range during operation is +5 °C ... +40 °C . The permis-
sible ambient temperature range for storage or transportation is –20 °C
... +70 °C. The maximum operating altitude is up to 2200 m (non opera-
ting 15000 m). 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 instrument) 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 be operated in any position, but the convection cooling
must not be impaired. The ventilation holes may not be covered. For
continuous operation the instrument should be used in the horizontal
position, preferably tilted upwards, resting on the tilt handle.
The specifi cations stating tolerances are only valid if the instrument
has warmed up for 30 minutes at an ambient temperature between
+15 °C and +30 °C. Values without tolerances are typical for an average
instrument.

Warranty and repair

HAMEG instruments are subjected to a strict quality control. Prior to
leaving the factory, each instrument is burnt-in for 10 hours. By inter-
mittent operation during this period almost all defects are detected.
Following the burn-in, each instrument is tested for function and quality,
the specifi cations are checked in all operating modes; the test gear is
calibrated to national standards.
The warranty standards applicable are those of the country in which the
instrument was sold. Reclamations should be directed to the dealer.
Only valid in EU countries
In order to speed reclamations customers in EU countries may also
contact HAMEG directly. Also, after the warranty expired, the HAMEG
service will be at your disposal for any repairs.
Return material authorization (RMA):
Prior to returning an instrument to HAMEG ask for a RMA number either
by internet (http://www.hameg.com) or fax. If you do not have an original
shipping carton, you may obtain one by calling the HAMEG service dept
(+49 6182 800 500) or by sending an email to service@hameg.com.

Maintenance

The exterior of the instrument should be cleaned regularly with a dusting
brush. Dirt that is diffi cult to remove on the casing and handle, the plastic
and aluminium parts, can be removed with a moistened cloth (99% water
+1% mild detergent). Spirit or washing benzine (petroleum ether) can
be used to remove greasy dirt. The screen may be cleaned with water
or washing benzine (but not with spirit (alcohol) or solvents), it must
then be wiped with a dry clean lint free cloth. Under no circumstances
must the cleaning fl uid get into the instrument. The use of other cleaning
agents can attack the plastic and paint surfaces.

Protective Switch Off

This instrument is equipped with a switch mode power supply. It has
both over voltage and overload protection, which will cause the switch
mode supply to limit power consumption to a minimum. In this case a
ticking noise may be heard.

Power supply

The instrument operates on mains/line voltages between 105 V
250 V . No means of switching to different input voltages has therefore
AC
been provided.
The power input fuse is externally accessible. The fuse holder and the 3
pole power connector is an integrated unit. The power input fuse can be
exchanged after the rubber connector is removed. The fuse holder can
be released by lever action with the aid of a screwdriver. The starting
point is a slot located on contact pin side. The fuse can then be pushed
out of the mounting and replaced.
The fuse holder must be pushed in against the spring pressure and
locked. Use of patched fuses or short circuiting of the fuse holder is not
permissible; HAMEG assumes no liability whatsoever for any damage
caused as a result, and all warranty claims become null and void.
Fuse type:
Size 5x20mm; 0.8A, 250V AC fuse;
must meet IEC specifi cation 127,
Sheet III (or DIN 41 662
or DIN 41 571, sheet 3).
Time characteristic: time lag.
