Field of application
The instrument is specified for operation in industry, light industry,
commercial and residential environments.
The instrument has been designed for indoor use. The permissible
ambient temperature range during operation is +10°C (+50°F) ...
+40°C (+104°F). It may occasionally be subjected to temperatures
b10°C (+50°F) and -10°C (+14°F) without degrading its
safety. The permissible ambient temperature range for storage or
transportation is -40°C (-40°F) ... +70°C (+158°F). The maximum
operating altitude is up to 2200m (non-operating 15000m). The
maximum relative humidity is up to 80%.
If condensed water exists in the instrument it should be
acclimatized before switching on. In some cases (e.g. extremely
cold oscilloscope) two hours should be allowed before the
instrument is put into operation. The instrument should be kept
in a clean and dry room and must not be operated in explosive,
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 between
+15°C (+59°F) and +30°C (+86°F). Values without tolerances are
typical for an average instrument.
EMC
This instrument conforms to the European standards regarding
the electromagnetic compatibility. The applied standards are:
Generic immunity standard EN50082-2:1995 (for industrial
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
electromagnetic 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
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
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 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
assumes no liability whats-
oever for any damage caused as a result, and all warranty claims
become null and void.
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!
