2. Safety
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropri-
ate CPG1000 precision digital pressure gauge has been selected in terms
of measuring range, design and specic measuring conditions.
Non-observance can result in serious injury and/or damage to the equip-
ment.
Further important safety instructions can be found in the individual
chapters of these operating instructions.
2.1 Intended use
The CPG1000 precision digital pressure gauge can be used as a calibration instrument
and also for any application which requires 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 author-
ised 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. Safety
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to equip-
ment.
The activities described in these operating instructions may only be carried
out by skilled personnel who have the qualications described below.
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 knowl-
edge 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.
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.
The CPG1000 is a precision digital pressure gauge. The sensor may be
bottom or back mounted. The case is about 10 cm in diameter and it may
be used as a hand-held gauge or it may be xed in place.
■
Battery operation:
Use AA alkaline batteries only! Only replace the batteries outside the
hazardous area!
■
Measuring instruments with an external power supply unit are not
approved for hazardous areas.
■
Operation of the serial interface in the hazardous area is prohibited.
■
Temperature range: -10 ... +55 °C

2. Safety
Further hazardous area safety instructions:
Observe the operating information and the relevant country-specic regula-
tions concerning use in hazardous areas (e.g. EN 60079-14).
The precision digital pressure gauge is not intended for use with ammable
substances. It is only suitable for installation in locations which provide
sucient protection against the intrusion of solid foreign objects or water
which could impair the safety.
The instructions in these operating instructions must be followed strictly in
order to guarantee safe operation.
Information/Approval for hazardous locations
WARNING!
■
Hazardous areas
An hazardous area, as used in this manual, refers to an area made
hazardous by the potential presence of ammable or explosive vapours.
These areas are also referred to as hazardous locations, see NFPA 70
Article 500.
® LR110460, Class I, Division 2, Group A, B, C, D
II 3G Ex nA IIB T6
KEMA 09ATEX0096 X
Ta = -10 ... +55 °C
WARNING!
Only precision digital gauges powered by alkaline batteries are approved
for use in hazardous rooms. Precision digital pressure gauges with an
external voltage supply are not approved for use in hazardous areas.
The replacement of any components impairs their suitability for use in
hazardous areas.

2. Safety
2.4 Special hazards
WARNING!
Observe the information given in the applicable type examination certi-
cate 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!
■
Only connect or disconnect the CPG1000 once the system has been
depressurised!
■
Observe the working conditions in accordance with chapter 3 "Speci-
cations".
■
Always operate the pressure indicator within its overpressure limits.
■
For hazardous media such as oxygen, acetylene, ammable or toxic
gases or liquids, and refrigeration plants, compressors, etc., in addition
to all standard regulations, the appropriate existing codes or regulations
must also be followed.
■
If it is obvious that safe operation of the instrument is no longer possi-
ble, the instrument must be put out of operation and marked in order to
secure it against inadvertent use.
■
The circuitry for connection to other devices should be designed with
particular care. Under certain circumstances internal junctions in exter-
nal devices (e.g. GND junctions with screen) could lead to impermissi-
ble voltage potentials that could impair the function of the device itself or
a device connected to it, or even destroy them.
■
The measurement signal of the reference (or test sample) can be inu-
enced by massive electromagnetic irradiation and/or the indication of
the signal could be completely absent.
■
If the CPG1000 is used in applications with oil as a pressure medium,
make sure it will not be used with ammable material or gases directly
afterwards since it can lead to dangerous explosions and danger to
personnel and machinery.
■
Residual media in the dismounted instrument can result in a risk to
persons, the environment and the equipment. Take sucient precaution-
ary measures.

2. Safety
DANGER!
Danger of death caused by electric current
Operation using a defective power supply unit (e.g. short circuit from the
mains voltage to the output voltage) can result in life-threatening voltages
at the instrument!
Special conditions for safe use
WARNING!
If the CPG1000 has been exposed to overload or sudden physical shock
(e.g. being dropped) it should be checked for signs of damage that may
cause concerns about safety. If there is any doubt, return the unit to WIKA
for evaluation. For information on returning the instrument see chapter
9.2 "Return".
The CPG1000 is not intended for use with ammable substances and must
be used only in locations which provide sucient protection against the
intrusion of solid foreign objects or water which could impair the safety.
CAUTION!
To avoid possible damage to the calibration reference or to equipment
under test:
■
If the message "OL" is displayed, the measuring range has been
exceeded and the pressure source must be removed immediately from
the CPG1000 in order to prevent damage to the internal sensor.
■
The maximum permitted torque of the thread is 13.5 Nm = 10 ftlbs. This
permitted torque must NEVER be exceeded.
■
When screwing the NPT thread of the CPG1000 to an adapter or
a process connection, it is necessary to use an additional sealing
compound, e.g. Teon tape between the threads.
■
The sealing has to be made with Teon tape directly via the NPT thread
and not via the manifold at the CPG1000.
