ration 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 instru-
ment has warmed up for 20 minutes at an ambient temperature
between +15 °C (+59 °F) and +30 °C (+86 °F). Values without
tolerances are typical for an average instrument.

Warranty and repair

HAMEG instruments are subject to a strict quality control. All
instruments are burned in for 10 hrs prior to shipment. By in-
termittent operation almost all early failures are detected. After
burn-in a thorough test of all functions and of quality is run, all
specifi cations and operating modes are checked.
In case of reclamations during the two years warranty period
please contact the dealer from whom you purchased your
HAMEG instrument. Customers from the Federal Republic of
Germany may directly contact HAMEG for warranty processing
in order to speed up the procedure.
The proceeding of repairs during the warranty period is subject
to our terms of warranty which are available on our web-site

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
and 250 V . No means of switching to different input voltages
AC
has therefore been provided.
The power input fuse is externally accessible. The fuse holder
and the 3 pole power connector is an integrated unit. The po-
wer 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 whatso-
ever for any damage caused as a result, and all warranty claims
become null and void.
