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
ambient temperature range during operation is +5 °C ... +40 °C. The
permissible ambient temperature range for storage or transportation is
–20 °C ... +70 °C. The maximum operating altitude is up to 2200 m (non
operating 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 ope-
ration. The instrument should be kept in a clean and dry room and
must not be operated in explosive, corrosive, dusty, or moist envi-
ronments. 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 rigorous quality control. Prior
to shipment each instrument will be burnt in for 10 hours. Intermittent
operation will produce nearly all early failures. After burn in, a fi nal
functional and quality test is performed to check all operating modes and
fulfi lment of specifi cations. The latter is performed with test equipment
traceable to national measurement standards.
Statutory warranty regulations apply in the country where the HAMEG
product was purchased. In case of complaints please contact the dealer
who supplied your HAMEG product.
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 (0) 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.
