• Take particular care when dealing with voltages exceeding 30 V/AC or 30 V/DC!
Even at these voltages, there is a danger of fatal electric shock if you touch electric
conductors.
• Do not use the device in rooms or under unfavourable ambient conditions in which
there are or could be combustible gases, vapours or dust.
These can distort the measurement.
• Use only measurement lines and accessories for the measurement that match the
specifications of the oscilloscope.
• If a safe operation can no longer be assumed, the device must be put out of op-
eration and secured against unintended operation. Safe operation can no longer
be assumed if:
- the product exhibits visible damage,
- does not function any longer 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 to a warm
environment. The condensation that forms might destroy your device. Allow the
device to reach room temperature before switching it on.
• Do not disassemble the product! There is risk of a life-threatening electric shock!
• Do not carelessly leave the packaging material lying around, since it could be-
come a dangerous plaything for children.
• The device is intended only for dry interior rooms (not bathrooms or similar damp
rooms). The device must not get wet or damp. There is risk of a life-threatening
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.
• Measurement instruments used at schools, training facilities, do-it-yourself and
hobby workshops should not be handled unless supervised by trained, respon-
sible personnel.
• If you have doubts about how the device 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.
• Regularly check the technical safety of the device and the measuring cables,
e.g., for damage to the casing or pinching of the cables etc. The device may
in no case be opened or used, if the covers have been removed.
!RISK OF FATAL INJURY!
Never exceed the maximum admissible input values. Never touch circuits or
parts of circuits when they may contain voltages greater than 30 V/AC rms
or 30 V/DC! Danger to life!
• If in doubt about how to connect the device correctly, or should any questions arise
that are not answered in these operating instructions, please contact our technical
service or another specialist

Intended Use
PP-80 / PP-100 / PP-200 is a passive, damped contact probe with low impedance. In con-
nection with an oscilloscope it allows the visual displaying of electric factors and signals. The
measuring lead is connected to the oscilloscope via two BNC sockets.
The maximum input variables indicated on the device must never be exceeded.
Any use other than that described above could lead to damage to this product and involves
risks such as short circuits, fire, electric shock, etc.
No part of the product may be modified or rebuilt, and the housing must not be opened.
Measurements are not permitted in damp rooms or outdoors, nor under adverse environmental
conditions.
Adverse environmental conditions are:
- Wet conditions or high air humidity,
- dust and flammable gases, vapours or solvents,
- thunderstorms or similar conditions such as strong electrostatic fields, etc.
This quick guide explains the safety measures that should be taken to make working with the
device as safe as possible.
Always observe the safety notes included in these operating instructions.
