0.1General information regarding
the CE marking
General information regarding the CE marking
The instruments fulll the regulations of the EMC directive. The
conformity test based on the actual generic- and product standards.
In cases where different limit values are applicable, the instrument
applies the severer standard. For emission the limits for residential,
commercial and light industry are applied. Regarding the immunity
(susceptibility) the limits for industrial environment have been used.
The measuring- and data lines of the instrument have much inuence
on emission and immunity and therefore on meeting the acceptance
limits. For different applications the lines and/or cables used may
be different. For measurement operation the following hints and
conditions regarding emission and immunity should be observed:
1. Data cables
For the connection between instrument interfaces and external devices,
(computer, printer etc.) sufciently screened cables must be used.
Without a special instruction in the manual for a reduced cable length,
the maximum cable length of a dataline must be less than 3 meters and
not be used outside buildings. If an interface has several connectors
only one connector must have a connection to a cable.
Basically interconnections must have a double screening.
2. Signal cables
Basically test leads for signal interconnection between test point and
instrument should be as short as possible. Without instruction in the
manual for a shorter length, signal lines must be less than 3 meters
and not be used outside buildings.
Signal lines must screened (coaxial cable - RG58/U). A proper ground
connection is required. In combination with signal generators double
screened cables (RG223/U, RG214/U) must be used.
3. Inuence on measuring instruments
Under the presence of strong high frequency electric or magnetic
elds, even with careful setup of the measuring equipment, inuence
of such signals is unavoidable.
This will not cause damage or put the instrument out of operation. Small
deviations of the measuring value (reading) exceeding the instruments
specications may result from such conditions in individual cases.
4. RF immunity of oscilloscopes.
4.1 Electromagnetic RF eld
The inuence of electric and magnetic RF elds may become visible
(e.g. RF superimposed), if the eld intensity is high. In most cases
the coupling into the oscilloscope takes place via the device under
test, mains/line supply, test leads, control cables and/or radiation.
The device under test as well as the oscilloscope may be effected by
such elds.
Although the interior of the oscilloscope is screened by the cabinet,
direct radiation can occur via the CRT gap. As the bandwidth of
each amplier stage is higher than the total –3dB bandwidth of the
oscilloscope, the inuence of RF elds of even higher frequencies
may be noticeable.
4.2 Electrical fast transients / electrostatic discharge
Electrical fast transient signals (burst) may be coupled into the
oscilloscope directly via the mains/line supply, or indirectly via test
leads and/or control cables. Due to the high trigger and input sensitivity
of the oscilloscopes, such normally high signals may effect the trigger
unit and/or may become visible on the TFT, which is unavoidable. These
effects can also be caused by direct or indirect electrostatic discharge.

prior to connecting any signals. It is prohibited to separate the
safety ground connection. If suspected that safe operation may
not be guaranteed do not use the instrument any more and lock
it away in a secure place.
Safe operation may be endangered if any of the following was
noticed:
– in case of visible damage.
– in case loose parts were noticed
– if it does not function any more.
– after prolonged storage under unfavourable conditions (e.g.
like in the open or in moist atmosphere).
1.4 Correct operation
Please note: This instrument is only destined for use by perso
nnel well instructed and familiar with the dangers of electrical
measurements. For safety reasons the oscilloscope may only
be operated from mains outlets with safety ground connector.
It is prohibited to separate the safety ground connection. The
plug must be inserted prior to connecting any signals.
The instrument is destined for in door use only.
1.5 Ambient conditions
Operating ambient temperature: +5 °C to +40 °C. During trans
port or storage the temperature may be –20 °C to +70°C. Please
note that after exposure to such temperatures or in case of
densation has evaporated before it may be turned on! Ordinarily
this will be the case after 2 hours. The oscilloscope is destined
for use in clean and dry environments. Do not operate in dusty
or chemically aggressive atmosphere or if there is danger of

No part of the instrument should be cleaned by the
use of cleaning agents (as f.e. alcohol) as they may
adversely affect the labeling, the plastic or lac-
quered surfaces.
The display can be cleaned using water or a glass cleaner (but
not with alcohol or other cleaning agents). Thereafter wipe the

is impossible to connect monitors or beamers via their analog

by the channel key light up. The channel number will be shown
in the top of the menu. By pushing the respective key of another
channel the menu will transfer to this channel.
4.2 Sensitivity, Y-Positioning, and Offset
The sensitivity of the analog inputs can be selected with the large
knob in the VERTICAL

selection. The knob is associated with the channel selected by
pushing the respective key. The sensitivity can be changed to
continuous control by pushing the knob once. The smaller one
of the knobs is used for vertical positioning.
