Proper operating conditions

Operation in the following environments: industry, business
and living quarters, small industry. The instruments are
destined for operation in dry, clean environments. They must
not be operated in the presence of excessive dust, humidity, or
chemical vapors neither in case of danger of explosion.
The maximum permissible ambient temperature during ope-
ration is +5 °C ... +40 °C. In storage or during transport the
temperature limits are: –20 °C ... +70 °C. In case of exposure
to low temperature or if condensation is to be suspected the
instrument must be left to stabilize for at least 2 hrs. prior to
operation.
In principle the instrument may be used in any position,
however, suffi cient ventilation must be ensured. Operation
for extended periods of time require the horizontal or tilted
(handle) position.
Do not block the ventilation holes.
Nominal specifi cations are valid after 30 minutes warm-up
at 23 °C. Specifi cations without tolerances are typical values
taken of average production units.

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 intermittent operation during this period almost
all defects are detected. Following the burn-in, each instru-
ment 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.

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 254 V . No line voltage selector.
AC AC

Change of line fuse

The line fuse is accessible on the rear panel. The power re-
ceptacle and the fuse holder constitute one unit. Change resp.
exchange of the fuse is only possible after the female part of
the line cord was removed. The fuse may only be exchanged
if the fuse holder is not damaged. In order to remove the fuse
use a screw driver and put it under the lid of the fuse holder,
then pull it forward and out. The fuse can be taken out of the
clips and exchanged.
Then insert the fuse holder and press it against the spring
force into its proper position. Repairing of fuses or the use of
another type are prohibited as well as any means to bridge a
defective fuse. Any damage to the instrument caused by such
measures will void the warranty.
