2 Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
CPG500 digital pressure gauge has been selected in terms of measuring range,
design and specific measuring conditions. Serious injuries and/or damage can occur
should these not be observed.
Further important safety instructions can be found in the individual chapters of
these operating instructions.
2.1 Int ended use
The CPG500 digital pressure gauge can be used as a calibration instrument and also for any
application which requires accuracy pressure measurement.
The CPG500 digit al pressure gauge has been designed and built solely for the intended use
described here, and may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.
Improper handling or operation of the CPG500 digital pressure gauge outside of its technical
specifications requires the instrument to be shut down immediately and inspected by an authorised
WIKA service engineer.
Handle electronic precision measuring instruments with the required care (protect from humidity,
impacts, strong magnetic fields, static electricity and extreme temperatures, do not insert any
objects into the instrument or its openings). Plugs and sockets must be protected from
contamination.
If the CPG500 digital pressure gauge is transported from a cold into a warm environment, the
formation of condensation may result in the instrument malfunctioning. Before putting it back into
operation, wait for the instrument temperature and the room temperature to equalise.
The manufacturer shall not be liable for claims of any type based on operation contrary to the
intended use.

2.2 Personnel qualifi cati on WARNING!
Risk of injury should qualification be insufficient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be
skilled personnel who have the qualifications described
below.
carried out by
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowledge of
country-specific regulations, current standards and directives, are capable of carrying out the work
described and independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
2.3 Special hazards
WARNING!
■ Use the CPG500 digital pressure gauge only with safe gases and liquids per
directive 67/548/EEC.
■ If it is obvious that safe operation of the instrument is no longer possible, the
instrument must be put out of operation and marked in order to secure it against
inadvertent use.
■ The measurement signal of the reference (or test sample) can be influenced by
massive electromagnetic irradiation and/or the indication of the signal could be
completely absent.
■ If the digital pressure gauge CPG500 is used in applications with oil as a pressure
medium, make sure it will not be used with flammable material or gases directly
afterwards since it can lead to dangerous explosions and danger to personnel
and machinery.
■ Digital pressure gauges should only be fitted or remored when the system is free
from pressure.
■ Observe the working conditions in accordance with chapter “3. Specifications”.
■ Always operate the pressure indicator within its overload limits.

4 Design and Function
4.1 Short descripti on / Description
The CPG500 is a digital pressure gauge featuring a Min/Max display function. Full scale (FS)
accuracy is ± 0.25% based on the upper limit of the measurement range.
Dynamic pressure peaks are measured at a sampling rate of 10 ms (100 measurement
values/second). The MIN/Max memory is continuously updated and rewritten.
4.2 Scope of delivery

5 Transport, packaging and st orage
5.1 Transport
Check the CPG500 digital pressure gauge for any damage that may have been caused by
transport. Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
5.3 Storage Permissible conditions at the place of storage:
■ Storage temperature: -20…+60 °C
■ Humidity: <85 % relative humidity (non-condensing)
Avoid exposure to the following factors:
■ Direct sunlight or proximity to hot objects
■ Mechanical vibration, mechanical shock (putting it down hard)
■ Soot, vapour, dust and corrosive gases
■ Potentially explosive environments, flammable atmospheres
Store the CPG500 digital pressure gauge in its orig inal packaging in a location that fulfills the
conditions listed above. If the original packaging is not available, pack and store the CPG500
digital pressure gauge as described below:
1. Wrap the CPG500 digital pressure gauge in an antistatic plastic film.
2. Place the CPG500 digital pressure gauge, along with shock-absorbent material, in the
packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag, containing a
desiccant, inside the packaging.
WARNING!
Before storing the digital pressure gauge (following operation),
remove any residual media. This is of particular importance if the medium
is hazardous to health, e.g. caustic, toxic, carcinogenic, radioactive, etc.
