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 specications contained in these operating instructions must be observed.
Improper handling or operation of the instrument outside of its technical specications
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 qualication
WARNING!
Risk of injury should qualication be insucient!
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 qualications
described below.
■
Keep unqualied 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-specic 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.

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 inammable 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.

2.4 Special hazards
WARNING!
Observe the information given in the applicable type examination
certicate and the relevant country-specic 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 "Specications".
■
Always operate the pressure calibrator within its overload limits. See
chapter 3 "Specications".
■
Do not apply a voltage greater than the specied voltage to the
instrument. See chapter 3 "Specications".
■
Residual media on the dismounted calibrator and/or sensors can
result in a risk to persons, the environment and the equipment. Take
sucient 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
inuenced by large electromagnetic eects 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 classied 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.
