2. Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
Display Pressure Switch model: PSD
Operating Instructions
4. Regulation Use
Any use of the Display Pressure Switch, model: PSD, which exceeds the
manufacturer’s specification, may invalidate its warranty. Therefore, any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage.

5. Operating Principle
KOBOLD is a leading international supplier of high quality sensors and monitoring
instruments among other things for measurement of pressure and temperature.
The PSD is the ideal combination of pressure switch and transmitter with a
pressure display. The parameters can be set on the device. The settings in
combination with a comprehensive set of options make the PSD suitable for a
wide range of demanding applications.
