Be especially careful when dealing with voltages higher than 25V 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.
Check the measuring device and its measuring cables for any damage before each measure-
ment. 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 optional probes outside of the marked handling area during a measurement.
There is danger of a life-threatening electric shock.
Do not use the appliance just before, while or shortly after a thunderstorm (lightning!/ over-
voltage!). Please make sure that your hands, shoes, clothing, the
fl
oor, the measuring instru-
ment and the measuring cables, switches and switching parts are absolutely dry.
Do not use the product inside of rooms, or in poor ambient conditions, where
fl
ammable
gases, vapours or explosive dust may be present or are present!
Do not use in the immediate proximity of strong magnetic or electromagnetic
fi
elds or trans-
mission aerials. These can affect the measurement.
Only use measuring cables or measuring accessories that are suitable for the DSO’s speci
fi
-
cations.
If a safe operation can no longer be assumed, the device has to be put out of operation and
secured against unintended operation. A safe operation can no longer be assumed, if:
- the device is visibly damaged,
- the device no longer functions and
- the device 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 environ-
ment. The condensation that forms might destroy your 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 carelessly leave the packaging material lying around since it could become a danger-
ous plaything for children.
The device is only intended for dry interior rooms (not bathrooms or similar damp rooms). The
device must not get wet or damp. There is a risk of a lethal electric shock!
On industrial sites, the accident prevention regulations of the association of the industrial
workers’ society for electrical equipment and utilities must be followed.
In schools, training centres, computer and self-help workshops, the use of measuring instru-
ments and accessories must be supervised by trained personnel in a responsible manner.
If you have doubts about how the equipment should be operated or how to connect it safely,
consult a trained technician.
Please handle the product carefully. The product can be damaged if crushed, struck or
dropped, even from a low height.
Pay attention to the detailed operating instructions in the measurement program (Help).
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 to the following symbols:
A triangle, containing an exclamation mark, in these operating instructions indicates
important information, which is to be observed without fail.
The “arrow” symbol indicates where special tips and notes on operation are pro-
vided.
This product has been CE-tested and meets the necessary European guidelines.
Periodically check the technical safety of the instrument and the connected
measuring cables, e.g. check for damage to the housing or crimping etc.
Never operate the device when it is open! !DANGER TO LIFE!
Do not exceed the maximum permitted input values. Never touch circuits or
parts of circuits with voltages greater than 25 V/AC rms or 35 V/DC! Danger to
life!
When using partial probes, the active measuring circuit must always be
placed against the internal conductor (probe head).

ITEM NO. 12 24 69 DSO-2202 USB
INTENDED USE
The oscilloscope unit is intended for use in combination with a Windows® based computer
with two USB 2.0 interfaces as a fully digital storage oscilloscope (short DSO) for the visuali-
sation of electrical quantities and signals. There are two independent input channels available
for measurement. The probes are connected to the DSO via BNC connectors. Operation and
display is performed using the enclosed measurement program. It is equivalent to a real oscil-
loscope operating interface. In addition, there is a spectrum analyser (FFT), mathematical
special functions and cursor for measuring signals.
The bandwidth and the sampling rate depend on the type, as follows:
DSO-1052 USB
50 MHz for 150 MS/s
DSO-1082 USB
80 MHz for 250 MS/s
DSO-1102 USB
100 MHz for 250 MS/s
DSO-2202 USB
200 MHz for 250 MS/s
The measured signals can be stored in different formats and called up or processed in other
programs.
For simple initial operation, user de
fi
ned appliance settings can be stored and called.
Never exceed the speci
fi
ed measurement voltage of 35 V/DC or 35 Vp/AC. Use partial
probes, if necessary. It may only be used in the measurement category range CAT I, for
signal voltages.
Any other use than that described above, could lead to damage to this product and involves
the risk of short circuits,
fi
re, electric shock, etc.
The product may not be modi
fi
ed or rebuilt nor should the casing be opened.
Measurement in a damp locations, outdoors or under adverse environmental conditions is not
permitted.
Unfavourable ambient conditions are:
- Wet conditions or high air humidity,
- Dust and
fl
ammable gases, vapours or solvent,
- Thunderstorms or similar conditions such as strong electrostatic
fi
elds etc.
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 explained in detail in the
“Help” function in the measurement program.
Detailed instructions on installing the device, driver installation and measurement modes can
be viewed from the measurement program’s “Help” option in the menu.
2. SAFETY INSTRUCTIONS AND HAZARD WARNINGS
Please read all the instructions before using this device, they include impor-
tant information on its correct operation.
The warranty will be void in the event of damage caused by failure to observe these safety

non-compliance with the safety instructions! Any warranty will be void in such cases.
The unauthorised conversion and/or modi
fi
cation of the product is not allowed for safety and
approval reasons (CE).
The earth connection of the measuring circuit is connected directly to the earth connection of
the USB connector.
Measurement devices and accessories should be kept away from children! Therefore, be
especially careful when children are around.
First, connect the BNC output of the probes to the oscilloscope unit, before you connect the
probe to the electric circuit that is to be tested. When the measurement is completed, please
disconnect the measuring contacts
fi
rst, before disconnecting the BNC probe output from the
oscilloscope unit.
