class 2. The instrument may be used in any position, however,
suffi cient ventilation must be assured as convection cooling is
used. For continuous operation prefer a horizontal or slightly
upward position using the feet.
Do not cover either the holes of the case nor the
cooling fi ns.
Specifi cations with tolerances are valid after a 30 minute warm-
up period and at 23 degrees C. Specifi cations without tolerances

are typical values of 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 na-
tional 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.

Maintenance

The instrument does not require any maintenance. Dirt may
be removed by a soft moist cloth, if necessary adding a mild
detergent. (Water and 1 %.) Grease may be removed with ben-
zine (petrol ether). Displays and windows may only be cleaned
with a moist cloth.
Do not use alcohol, solvents or paste. Under no cir-
cumstances any fl uid should be allowed to get into
the instrument. If other cleaning fl uids are used

damage to the lacquered or plastic surfaces is pos-
sible.

Mains voltage

A main voltage of 115V and 230V can be chosen. Please check
whether the mains voltage used corresponds with the volta-
ge indicated by the mains voltage selector on the rear panel.
If not, the voltage has to be changed. In this case the line fuse
has to be changed, too.
Please note:
After changing the main voltage, the line fuse has
to be changed. Otherwise the instrument may be

Changing the line fuse

The fuses are accessible from the outside and contained in
the line voltage connector housing. Before changing a fuse
disconnect the instrument from the line, the line cord must
be removed. Check fuse holder and line cord for any damages.
Use a screw driver to loosen the fuse holder screw counter-
clockwise while pressing the top of the fuse holder down. The
top holding the fuse will then come off. Exchange the defective
fuse against a correct new one.
It is forbidden to repair defective fuses or to bridge them by any
means. Any damage caused this way will void the warranty.
