Important hints
This oscilloscope is easy to operate. The logical arrangement of
the controls allows anyone to quickly become familiar with the
operation of the instrument, however, experienced users are also
advised to read through these instructions so that all functions
are understood.
Immediately after unpacking, the instrument should be checked
for mechanical damage and loose parts in the interior. If there is
transport damage, the supplier must be informed immediately.
The instrument must then not be put into operation.

Use of tilt handle
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 oscilloscope (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 it
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.
Safety
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
hasleft 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
oscilloscope 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 I (three conductor power cord
with protective earthing conductor and a plug with earthing
contact). The accessible metal parts (case, sockets, jacks) and
the mains/line supply contacts (live, neutral) have been tested
against insulation breakdown with 2200V DC. 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.
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 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).
Intended purpose and operating conditions
Attention!
This instrument must be used only by qualified experts who
are aware of the risks of electrical measurement.
Due to safety reasons the instrument must only be connected to
a properly installed power outlet, containing a protective earth
conductor. The protective earth connection must not be broken.
The mains/line plug must be inserted before connections are
made to measuring circuits.
CAT I
This instrument is intended for measurement of circuits either
not at all or not directly connected to mains/line (CAT I). Direct
measuring (without galvanic separation) within measuring
category II, III and IV circuits is inadmissible.
Circuits of a device under test are not connected directly with
mains/line if the device under test is operated via an isolation
transformer (Safety Class II). It is also possible to use suitable
transducers (e.g. Current Probe) that meet the demands of
protective class II, to measure indirect at mains/line. The
transducer’s measuring category must be observed.
Measuring Categories
The measuring category relates to transients on mains/line.
Transients are short and fast voltage and current changes that
may appear periodically or aperiodically. The amplitude of
transients increases with decreasing distance to the low voltage
installation source.
Category IV:
has the highest demands on isolation etc. and is
required for measurement at the low voltage installation source
(e.g. at the supply meter).
Category III:
is for measurement within the building installation
at e.g. terminal block, power switch, fixed motor, wall outlet etc.
Category II:
measurement at circuits connected to the low
voltage installation such as home appliances, portable tools etc.
