Subject to change without notice
on which the technical data are based. Purchase of the
HAMEG scope tester HZ60
, 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 aluminum
parts, can be removed with a moistened cloth (99% water
+1% mild detergent). Spirit or washing benzene (petroleum
ether) can be used to remove greasy dirt. The screen may
be cleaned with water or washing benzene (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

Fuse type:
Size 5x20mm; 0.8A, 250V AC fuse;
must meet IEC specification 127,
Sheet III (or DIN 41 662
or DIN 41 571, sheet 3).
Time characteristic: time lag.
Attention!
There is a fuse located inside the instrument within the
switch mode power supply:
Size 5x20mm; 0.8A, 250V AC fuse;
must meet IEC specification 127,
Sheet III (or DIN 41 662
or DIN 41 571, sheet 3).
Time characteristic: fast (F).
The operator must not replace this fuse!
should be kept in a clean and dry room and must not be
operated in explosive, corrosive, dusty, or moist environ-
ments. 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 instru-
ment.
EMC
This instrument conforms to the European standards regar-
ding the electromagnetic compatibility. The applied standards
are: Generic immunity standard EN50082-2:1995 (for indus-
trial environment) Generic emission standard EN50081-1:1992
(for residential, commercial and light industry environment).
This means that the instrument has been tested to the highest
standards.
Please note that under the influence of strong electro-
magnetic fields, such signals may be superimposed on the
measured signals.
Under certain conditions this is unavoidable due to the
instrument’s high input sensitivity, high input impedance and
bandwidth. Shielded measuring cables, shielding and earthing
of the device under test may reduce or eliminate those
effects.
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 be 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 warranty.
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 warranty 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
