2. Safety
2.1 Intended use
The model CPH65I0 intrinsically-safe hand-held calibrator can be used as a calibration
reference or in any application requiring high-accuracy pressure measurement.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specications contained in these operating instructions must be observed.
Improper handling or operation of the instrument outside of its technical specications
requires the instrument to be taken out of service immediately and inspected by an
authorised WIKA service engineer.
Handle electronic precision measuring instruments with the required care (protect from
humidity, impacts, strong magnetic elds, 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 instrument is transported from a cold into a warm environment, the formation of
condensation may result in instrument malfunction. 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 qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to
equipment.
■
The activities described in these operating instructions may only
be carried out by skilled personnel who have the qualications
described below.
■
Keep unqualied personnel away from hazardous areas.

2. Safety
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-specic 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 Additional safety instructions for instruments per ATEX
WARNING!
Non-observance of these instructions and their contents may result in
the loss of explosion protection.

WARNING!
Further hazardous area safety instructions:
Observe the operating information and the relevant state regulations
concerning use in hazardous areas (e.g. EN IEC 60079-14).
The model CPH65I0 intrinsically-safe hand-held pressure calibrator has
been designed for use in hazardous areas. In these areas there is the
possibility of inammable or explosive gases being present.
The model CPH65I0 intrinsically-safe hand-held pressure calibrator has
been designed to be intrinsically safe. This means that connection with
other equipment that is in an intrinsically-safe circuit will not lead to arcs
capable of causing ignition, so long as the parameters are complied with.
Information/Approval for hazardous locations
WARNING!
Hazardous Areas
A hazardous area, as used in these operating instructions, refers to
an area made hazardous by the potential presence of ammable or
explosive vapours. These areas are also referred to as hazardous
locations.

WARNING!
The replacement of components may compromise the explosion
protection. Service and repair must be carried out by the manufacturer.
2.4 Special hazards
WARNING!
Observe the information given in the applicable type examination
certicate and the relevant country-specic regulations for installation
and use in hazardous areas (e.g. IEC 60079-14, NEC, CEC).
Non-observance can result in serious injury and/or damage to
equipment.
For additional important safety instructions for instruments with ATEX
approval see chapter 2.3 "Additional safety instructions for instruments
per ATEX".
WARNING!
■
Pressure sensors should only be mounted or dismounted when the
system is free from pressure.
■
Observe the working conditions in accordance with chapter
3 "Specications".
■
Always operate the pressure calibrator within its overload limits. See
chapter 3 "Specications".
■
Do not apply a voltage greater than the specied voltage to the
instrument. See chapter 3 "Specications".
■
Residual media on the dismounted calibrator and/or sensors can
result in a risk to persons, the environment and the equipment. Take
sucient precautionary measures.
■
Only use those accessories available from WIKA for the calibrator.
■
Make sure that the test probes never contact a voltage source while
the test cables are connected to the current terminals.
■
The measurement signal of the reference (or test sample) can be
inuenced by large electromagnetic eects and the display of the
signal may be lost completely.

2. Safety
WARNING!
■
Do not use the calibrator if it is damaged. Before using the
instrument, check that there are no cracks or missing plastic parts on
the case. Pay particular attention to the insulation of the connectors.
■
The battery cover must be closed and locked in place before the
instrument is operated.
■
Remove the test cables from the instrument before opening the
battery compartment.
■
Inspect the test cables for damaged insulation or exposed metal.
Check the continuity of the leads. Damaged test leads should be
replaced before using the instrument.
■
When using test probes, keep ngers away from the test probe
contacts. Place ngers behind the nger guards on the test probes.
■
Do not use the instrument if it is not working properly. The instrument
protection might be compromised. If in doubt, have the instrument
checked.
■
Only use the instrument in classied areas for which the calibrator is
approved.
■
Disconnect test leads before changing to another measurement or
generation function.
■
To avoid false readings, replace the battery as soon as the battery
indicator appears.
■
Use the correct connection, the proper function and the correct
measuring range for measurements.
■
When screwing an adaptor onto the NPT thread of the calibrator, a
sealing material must also be used (e.g. PTFE tape).
■
When screwing on, use a spanner on the pressure connection for
xing to the calibrator, in order to avoid unnecessary stress on the
case.

4.1 Description
The model CPH65I0-S1/S2 intrinsically-safe hand-held pressure calibrator has been
designed so that it is simple to handle, but is also a very versatile pressure calibrator.
The two internal reference pressure sensors, combined with current input, pressure
switch function and a resistance thermometer, enable the CPH65I0-S1/S2 to calibrate
practically any pressure instrument.
The model CPH65I0-S1 intrinsically-safe hand-held pressure calibrator has a single
integrated pressure sensor; the model CPH65I0-S2 intrinsically-safe hand-held
pressure calibrator has two integrated pressure sensors. The CPH65I0-S1 uses
connection P1 for all pressure measurements. Connection P2 is only used in the
CPH65I0-S2. Thus, the pressure-related menu selection for the CPH65I0-S1 is limited
to connection P1 only. All other CPH65I0-S1 features and functions are identical to the
CPH65I0-S2.

5. Transport, packaging and storage
5. Transport, packaging and storage
5.1 Transport
Check hand-held pressure calibrator 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
■
Relative humidity: 5 ... 95 % r. h. (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
Store the hand-held pressure calibrator in its original packaging in a location that fulls
the conditions listed above. If the original packaging is not available, pack and store the
instrument as described below:
1. Wrap the instrument in an antistatic plastic lm.
2. Place the instrument, along with shock-absorbent material, in the packaging.
WARNING!
Before storing the instrument (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.
