Operating Instructions
Digital hand oscilloscope DSO-2154
Item No. 2390916
Intended use
This product is designed to provide a visual representation of electrical quantities and
signals. Four input channels are available for taking measurements. The measuring leads are
connected to the oscilloscope via BNC sockets. Measurements are displayed on a 17.78 cm
(7 inch) colour LCD with an 800 x 480 pixel resolution. The measured signals can be displayed
on the LCD or a PC via USB cable.
The maximum input quantities indicated on the device must never be exceeded.
These safety instructions are primarily intended to explain safety measures in order to make
working with the device as safe as possible. The individual device functions are explained in
more detail in the help menu of the oscilloscope or the operating instructions.
Always observe the safety instructions and the help menus!

Safety information
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety information and information on
proper handling in these operating instructions, we will assume no liability for
any resulting personal injury or damage to property. Such cases will invalidate
the warranty/guarantee.

high humidity, moisture, combustible gases, vapours and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, stop using it and prevent
unauthorised use. Safe operation can no longer be guaranteed if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in adverse ambient conditions or
- has been subjected to any serious transport-related stress.
• Handle the product with care. Jolts, impacts or a fall even from a low height may
damage the product.
• Safety Sheet
• Quick Guide
• 4x Measurement probes
• 2x Adjustable measurement probes
• Consult a technician if you are not sure how to use or connect the product, or if
you have concerns about safety.
• Maintenance, modifications and repairs may only be carried out by a technician
or a specialist repair centre.
• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel. .
b) Connected devices
Always observe the safety information and operating instructions of any other
devices which are connected to the product.
c) Electrical safety
• The mains socket must be located near to the device and be easily accessible.
• The product must only be powered by a standard mains socket connected to the
public grid. Before plugging the product in, check that the voltage indicated on the
product corresponds to the voltage of your electricity supplier.
• Never unplug the mains plug by pulling on the cable. Always use the grips on
the plug.
• Unplug the mains plug from the mains socket if you do not plan to use the product
for an extended period of time.
• For safety reasons, disconnect the mains plug from the mains socket during
thunderstorms.
• Ensure that the mains cable is not squeezed, bent, damaged by sharp edges or
subjected to mechanical stress. Avoid excess thermal stress on the mains cable
due to excessive heat or cold. Do not modify the mains cable. Failure to adhere
to these instructions may lead to damage of the mains cable. A damaged mains
cable can cause a fatal electric shock.
• Do not touch the mains cable if there are any signs of damage. Power down
the respective mains socket (e.g. via the respective circuit breaker), and then
carefully unplug the mains plug from the mains socket. Never use the product if
the mains cable is damaged.
• Damaged mains cables must be replaced by the manufacturer, an authorised
repair centre or a qualified electrician.
• Never connect or disconnect power plugs when your hands are wet.
• Only use the power cable and power adapter supplied with the product and
certified for use in your country.
• Never switch the device on immediately after moving it from a cold to a warm
environment. The condensation generated may destroy the product. Leave the
device switched off and allow it to reach room temperature.
d) Persons and product
• Do not disassemble the product. This may cause a fatal electric shock!
• Store the oscilloscope in a well-ventilated place. Make sure that the instrument is
properly ventilated. Refer to the operating instructions for details.
• Do not work in areas where there is a danger of explosion.
• Keep all surfaces of the product clean and dry.
• Do not use the device in rooms or unfavourable ambient conditions in which there
are or could be combustible gases, vapours or dust.
e) Measuring mode
• Ensure that the probes are connected in the correct polarity. Do not connect the
negative measuring lead to the positive pole.
• Warning: The four channels of the oscilloscope are not electrically isolated. The
channels should adopt a common ground during measurement. To prevent short
circuits, the two probe grounds must not be connected to different non-isolated
DC levels. The oscilloscope ground wire should be connected as follows:
Probe
Signal
Input
Ground Clip
• AC power cannot be measured when the AC-powered oscilloscope is connected
to an AC-powered PC through the ports.
• Only use the supplied power adapter that is certified for use in your country.
• When the probe or test lead is connected to a voltage source, do not connect or
disconnect the probe or test lead at random.
• This instrument is grounded through the power adapter grounding conductor. To
avoid an electric shock, the grounding conductor must be grounded. The product
must be grounded properly before being connected to its input or output terminal.
• When powered by an AC power source, the AC power source cannot be
measured directly, as the testing ground and power adapter ground conductor
are connected, and this would cause a short circuit.
