Subject to change without notice
General
corrosive, dusty, or moist environments. The oscilloscope 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 specifications stating tolerances are only valid if the
instrument has warmed up for 30minutes at an ambient
temperature b15°C (+59°F) and +30°C (+86°F). Values
without tolerances are typical for an average instrument.
Warranty
HAMEG
warrants to its Customers that the products it
manufactures and sells will be free from defects in materials
and workmanship for a
period of 2 years
. This warranty shall not
apply to any defect, failure or damage caused by improper use
or inadequate maintenance and care.
HAMEG
shall not obliged
to provide service under this warranty to repair damage resulting
from attempts by personnel other than
HAMEG
representatives
to install, repair, service or modify these products. In order to
obtain service under this warranty, Customers must contact
and notify the distributor who has sold the product. Each
instrument is subjected to a quality test with 10 hour burn-in
before leaving the production. Practically all early failures are
detected by this method. In the case of shipments by post, rail
or carrier the original packing must be used. Transport damages
and damage due to gross negligence are not covered by the
guarantee. In the case of a complaint, a label should be attached
to the housing of the instrument which describes briefly the
faults observed. If at the same time the name and telephone
number (dialing code and telephone or direct number or
department designation) is stated for possible queries, this
helps towards speeding up the processing of guarantee claims.
Maintenance
Various important properties of the oscilloscope should be
carefully checked at certain intervals. Only in this way is it largely
certain that all signals are displayed with the accuracy on which
the technical data are based. Purchase of the new
HAMEG
scope tester HZ 60, which despite its low price is highly suitable
for tasks of this type, is very much recommended.
The exterior of the oscilloscope should be cleaned regularly
with a dusting brush. Dirt which is difficult 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 may the cleaning fluid 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
100V
AC
and 240V
AC
. No means of switching to different input
voltages 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 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

HAMEG assumes no liability

claims become null and void.
