To view the screen from the best angle, there
are three different positions
(C, D, E) for
setting up the instrument. If the instrument is
set down on the floor after being carried, the
handle automatically remains in the upright
carrying position
(A) . In order to place the
instrument onto a horizontal surface, the
handle should be turned to the upper side of
the Spectrum Analyzer
(C) . For the D position
(10 inclination) , the handle should be turned
to the opposite direction of the carrying
position until it locks in place automatically
underneath the instrument. For the E position
(20 inclination) , the handle should be pulled
to release it from the D position and swing
backwards until if locks once more. The
handle may also be set to a position for
horizontal carrying by turning it to the upper
side to lock in the B position. At the same time,
the instrument must be lifted, because
otherwise the handle will jump back.
This instrument has been designed and tested
in accordance with
IEC Publication 1010-1,
Safety requirements for electrical equipment
for measurement, control, and laboratory
use.
The CENELEC regulations EN 61010-1
correspond to this standard. It has left the
factory in a safe condition. This instruction
manual contains important information and
warnings which have to be followed by the
user to ensure safe operation and to retain the
Spectrum Analyzer in a safe condition.
The case, chassis and all measuring terminals
are connected to the protective earth contact
of the appliance inlet. The instrument operates
according to
Safety Class l (three-conductor
power cord with protective earthing conductor
and a plug with earthing contact)
. The mains/
line plug shall only be inserted in a socket
outlet provided with a protective earth contact.
The protective action must not be negated by
the use of an extension cord without a
protective conductor. The mains/line plug
should be inserted before connections are
made to measuring circuits. The grounded
accessible metal parts
(case, sockets, jacks)
and the mains/line supply contacts (line/live,
neutral) of the instrument have been tested
against insulation breakdown with 2200VDC.
Under certain conditions, 50Hz or 60Hz hum
voltages can occur in the measuring circuit
due to the interconnection with other mains/
line powered equipment or instruments. This
can be avoided by using an isolation
transformer
(Safety Class 11) between the
mains/line outlet and the power plug of the
device being investigated. Most cathode-ray
tubes develop X-rays. However,
the dose
equivalent rate falls far below the maximum
permissible value of 36pA/kg (0.5mR/h).
Whenever it is likely that protection has been
impaired, the instrument shall be made
Safety
inoperative and be secured against any
unintended operation. The protection is likely
to be impaired if, for example, the instrument:
shows visible damage.
fails to perform the intended measurements.
has been subjected to prolonged storage
under unfavorable conditions (e. g. in the
open or in moist environments).
has been subject to severe transport stress
(e. g. in poor packaging).
The instrument has been designed for indoor
use. The permissible ambient temperature
range during operation is + 10
(+50 F)~
+40 (+104 F). It may occasionally be
subjected to temperatures b10
(+50 F) and -10 (+14 F) without
degrading its safety. The permissible am
bient temperature range for storage or
transportation is -40
(-40 F)~+70
(+158 F). The maximum operating altitude
is up to 2200m (non-operating 1500m) . 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 spectrum
analyzer) 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,
dusty, or moist environments. The spectrum
analyzer can be operated in any position, but
the convection cooling must not be impaired.
For continuous operation the instrument
should be used in the horizontal position,
preferably tilted upwards, resting the tilt
handle.

Warranty
ATTEN warrants to its Customers that the
products it manufactures and sells will be free
from defects in materials and workmanship for
a
period of 1 years. This warranty shall not
apply to any defect, failure or damage caused
by improper use or inadequate maintenance
and care. ATTEN shall not be obliged to
provide service under this warranty to repair
damage resulting from attempts by personnel
other than ATTEN 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 it is
recommended that the original packing is
carefully preserved. Transport damages and
damage due to gross negligence are not cover
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.
Various important properties of the Spectrum
Analyzer should be carefully checked at
certain intervals. Only in this it largely certain
that all signals are displayed with the accuracy
on which the technical data are based.
