2.2 Safety instructions
Safety instructions according to product’s life stages
All safety instructions in this document are based on the results of a risk assessment.
Pfeiffer Vacuum has taken into account all the relevant life stages of the product.
Risks during installation
WARNING
Risk of injury resulting from overpressure in the vacuum system
Opening tensioning pieces with an overpressure > 1000 hPa in the vacuum system can lead to inju-
ries as a result of flying parts, and escaping process medium could prove harmful to health.
Elastomer seals in KF connections (e.g. O-rings) are not resistant to pressures > 2500 hPa. This
could prove harmful to health due to escaping process medium.
►Do not open any tensioning pieces when overpressure is prevalent in the vacuum system.
►Use suitable tensioning pieces for overpressure.
►Use tensioning pieces which can only be opened and closed using a tool (e.g. tightening strap-
circlip).
►Use sealing rings with an outer centering ring.

3 Product description
3.1 Identifying the product
You will need all the data from the rating plate to safely identify the product when communicating with
Pfeiffer Vacuum.
1. Read the data on the product rating plate.
2. Record this data.
3. Always have all rating plate specifications to hand.
3.2 Function
The handheld measurement instrument has a combined Piezo/Pirani sensor and is temperature-com-
pensated. The use of two physical measuring methods makes a high resolution possible over the entire
measuring range. You can connect the handheld measurement instrument to suitable flange connec-
tions and if suitable batteries are used, you can operate it directly in a vacuum. The pressure is continu-
ously displayed over the entire measuring range. The integrated data logger function makes it possible
to store up to 2000 measured values in the handheld measurement instrument.
Measuring principle
The handheld measurement instrument operates in the low vacuum range with an internal piezo-resis-
tive silicon sensor. The influence of pressure causes deformation of a thin diaphragm that has a resist-
ance bridge mounted on its rear side. The resulting unbalance of the measuring bridge is a measure of
the absolute pressure acting on the diaphragm. For the medium vacuum range, the handheld measure-
ment instrument uses an internal Pirani sensor that uses the heat conductivity of gases for vacuum
measurement. Here, the handheld measurement instrument heats a filament in a measuring bridge to a
constant temperature. The necessary bridge voltage is a measure of the absolute pressure.
USB interface
You can use the USB interface to:
●Configure unit parameters (Pfeiffer Vacuum protocol)
●Record and read out measured values (DokuStar software)
●Retrieve data or change parameters from a program provided by the customer with the LabView
driver

5 Installation
5.1 Establishing vacuum connection
WARNING
Risk of injury resulting from overpressure in the vacuum system
Opening tensioning pieces with an overpressure > 1000 hPa in the vacuum system can lead to inju-
ries as a result of flying parts, and escaping process medium could prove harmful to health.
Elastomer seals in KF connections (e.g. O-rings) are not resistant to pressures > 2500 hPa. This
could prove harmful to health due to escaping process medium.
►Do not open any tensioning pieces when overpressure is prevalent in the vacuum system.
►Use suitable tensioning pieces for overpressure.
►Use tensioning pieces which can only be opened and closed using a tool (e.g. tightening strap-
circlip).
►Use sealing rings with an outer centering ring.
NOTICE
Impairment from contamination and damage
Touching the devices or components with bare hands increases the desorption rate and leads to in-
correct measurements. Dirt (e.g. dust, fingerprints, etc.) and damage impair the function.
►When working on high or ultra high vacuum systems, always wear clean, lint-free and powder-
free laboratory gloves.
►Only use clean tools.
►Make sure that the connection flanges are free of grease.
►Remove protective caps and protective covers from flanges and connections only when necessa-
ry.
►Carry out all work in a well lit area.
Prerequisites
●Appropriate ambient conditions
●Operating temperature within permissible range
●Adequate room available for electrical connection (e.g. permissible bending radii for cables)
Recommendations
►Where possible, ensure that the handheld measurement instrument is not exposed to any vibra-
tions during operation, as vibrations in general will lead to deviations in the measured values.
►Install the handheld measurement instrument in a horizontal to upright position (flange facing
downwards).
–This prevents condensate and particles from accumulating in the measurement chamber.
►Fit a seal with centering ring and filter for applications susceptible to pollution and to protect the
measuring system against contamination.
►Electrically connect the vacuum flange to the earthed conductor, e.g., by contacting the earthed
vacuum chamber through a metal tensioning piece.
Procedure
1. Remove the protective cap and store in a safe place.
2. Install the handheld measurement instrument on the vacuum system, with vacuum components
from the Pfeiffer Vacuum Components Shop.
