INTENDED USE
The digital oscilloscope is intended to be used for visualising electrical magnitudes and signals.
Two independent input channels are available for the electric measurement. The probes are
connected to the oscilloscope via BNC connectors.
The measured signals can be stored and displayed as a reference.
The control is performed via VDU based control menus.
The maximum measuring voltage (300 V/DC/ACpk) should not be exceeded. Use divider
probes if necessary.
The device should only be connected and used with an earthed shockproof socket connected
the public alternating current grid.
Any other use than that described above, could lead to damage to this product and involves the
riskofshortcircuits,re,electricshock,etc.

Do not make measurements in damp locations, outdoors or under adverse environmental
conditions. Unfavourable ambient conditions are:
Wet conditions or high air humidity,•
Dustandammablegases,vapoursorsolvent,•
Thunderstormsorsimilarconditionssuchasstrongelectrostaticeldsetc.•
Always observe the safety notes included in these operating instructions.
This quick guide explains the safety measures that should be taken to make working with the
device as safe as possible. The individual functions of the device are described in more detail
in the enclosed operating manual.
SAFETY INSTRUCTIONS AND HAZARD WARNINGS
Please read all of the operating instructions before using the product for the
rst time; they contain important information about the correct operation.
The warranty will be void for damage arising from non-compliance with these •
operating instructions! We do not assume any liability for any consequential
damage!
Nor do we assume any liability for material and personal damage caused by •
improper use or non-compliance with the safety instructions! The warranty is
voided in these cases.
Theunauthorised conversionand/or modicationof theproduct isinadmissible•
because of safety and approval reasons (CE).
The construction of the product corresponds to protection class 1. Only a properly •
earthed mains socket (100 – 240 V/AC) connected to the public power supply
should be used.
Measuring devices and devices connected to the power supply should be kept •
out of the reach of children. Therefore, be especially careful when children are
around.
First, connect the BNC output of the measurement cable to the oscilloscope, then •
connect the probe to the electric circuit to be measured. The measuring completed,
please disconnect the measuring contacts rst before disconnecting the BNC
output of the probe from the oscilloscope.
Take particular care when dealing with voltages exceeding 25 V/AC or 35 V/DC! •
Even at such voltages you can receive a life-threatening electric shock if you come
into contact with live electric wires.
Prior to each measurement, check your instrument and its measuring leads for •
damage. Never make any measurements if the protecting insulation is defective
(torn, missing etc.)
To avoid electric shock, do not to touch the connections/measuring points directly •
or indirectly during measurements.
Never touch the probes outside of the marked handling area during a measurement. •
There is danger of a life-threatening electric shock.
Do not use the device shortly before or after a thunderstorm (lightning! / high-•
energyovervoltages!).Makesurethatyourhands,shoes,clothing,theoor,the
measuring device and/or measuring lines, the circuits and its parts are always dry.
Do not use the product inside of rooms, or in poor ambient conditions, where •
ammablegases,vapoursorexplosivedustmaybepresentorarepresent!
Do not operate the device near to:•
strongmagneticorelectromagneticeldsor -
transmitting aerials or HF generators. -
These can affect the measurement.
Only use measuring cables, or equipment, appropriate for the oscilloscope’s •
specicationswhenmakingmeasurements.
If you have reason to assume that safe operation is no longer possible, disconnect •
the device immediately and secure it against inadvertent operation. It can be
assumed that safe operation is no longer possible if:
the device is visibly damaged, -
the device no longer works and -
the unit was stored under unfavourable conditions for a long period of time or -
it has been subjected to considerable stress in transit. -
Never switch the device on immediately after having taken it from a cold in to a •
warm environment. The condensation that forms could cause serious damage to
the device. Allow the device to reach room temperature before switching it on.
Never disassemble the product! There is a risk of a lethal electric shock!•
Do not leave packing materials unattended. They may become dangerous •
playthings for children.
The product is only suited for dry indoor locations (not bathrooms or similar damp •
interiors). The device must not get wet or damp. There is a risk of a lethal electric
shock!
In commercial institutions, the accident prevention regulations of the Employer’s •
Liability Insurance Association for Electrical Systems and Operating Materials are
to be observed.
If you have doubts about how the equipment should be operated or how to safely •
connect it, consult a trained technician.
Handle the product with care. It can be damaged through impact, blows, or •
accidental drops, even from a low height.
Please also note the enclosed detailed operating instructions.•
This device left the manufacture’s factory in a safe and perfect condition. We kindly request
the user to observe the safety instructions and warnings contained in the enclosed operating
instructions so this condition is maintained and to ensure safe operation. Please pay attention
