Warranty

HAMEG instruments are subject to a strict quality control. All
instruments are burned in for 10 hrs prior to shipment. By
intermittent operation almost all early failures are detected. After
burn-in a thorough test of all functions and of quality is run, all
specifications and operating modes are checked.
However, a component may fail after some time. Consequently,
HAMEG warrants all instruments for 2 years regarding proper
function provided there were no manipulations of the instrument.
Only the original packing is considered adequate for shipping by
train, postal or parcel service. The warranty will be voided if
damage during transport is due to neglect.
In case of any warranty claim please stick a label
to the case of the instrument indicating the cause
of trouble concisely. Add your address, name and phone
number including extension dialling. This will help to
accelerate processing your claim by contacting you for
further details.

removed by a soft moist cloth, if necessary adding a mild

with a moist cloth.

to the lacquered or plastic surfaces is possible.
Line voltage selector
The instrument is destined for operation on 115 or 230 V mains,
50/60 Hz. The proper line voltage is selected with the
voltage selector. It is necessary to change the fuse observing the
proper values printed on the back panel.

Change of fuse

The mains fuse is accessible on the back panel. A change of
the fuse is only allowed after the instrument was disconnected
from the line and the power cord removed. Fuse holder and
power cord must not show any sign of damage. Use a screw
driver to loosen the fuse holder screw counterclockwise 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. Any "repair" of a defective fuse or bridging is dangerous
and hence prohibited. Any damages to the instrument incurred by
such manipulations are not covered by the warranty.
