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 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 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.

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

2. Safety
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!
■
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 inu-
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 sucient precaution-
ary measures.

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 sucient 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. Teon tape between the threads.
■

4.1 Description
The CPG1000 combines the high accuracy of the digital electronics with the convenience
and easy handling of an analogue test gauge. Accurate to ±0.05 % FS the CPG1000 can
be used as a calibration reference or in any application requiring high accuracy pressure
measurement.
Many user-congurable functions have been implemented in the CPG1000, for example
sampling rate, tare, damping, automatic disconnection and Min-Max measurement. Once
the digital pressure gauge is congured, the settings can be locked and password protect-
ed to prevent unauthorised changes to the conguration.

4.4 Integrated data logger
From the rmware Version 3.00 onwards, the CPG1000 has an integrated data logger. This
data logger can be activated and operated using the CPGLog software. For this, see the
CPGLog operating instructions.
4.5 External voltage supply
The standard version is supplied with three AA alkaline batteries. In the optional DC 24V
powered version with an external voltage supply, the alkaline batteries are not installed.
Connect the DC 24 V voltage supply to the terminals at the rear of the measuring instru-
ment. Ensure the polarity is correct. Do not insert any batteries if an external power supply
is being used.
WARNING!
Prior to connecting the mains adapter to the mains power supply make
sure that the operating voltage specied on the mains adapter matches the
mains voltage.
Measuring instruments with an external power supply unit are supplied
without batteries inserted. For operation with an external voltage source,
batteries MUST NOT be inserted. Measuring instruments with an external
power supply unit are not approved for the hazardous areas.

4.5.1 Battery replacement
WARNING!
Do not change the alkaline batteries in hazardous area!
Rotate the faceplate of the CPG1000 to the left by approx. 90° and remove it. After that the
front panel of the pressure gauge can be removed and the battery compartment is acces-
sible. Insert the three AA-sized alkaline batteries in correct polarity.
WARNING!
Always use AA alkaline batteries and observe the correct polarity. During
enclosure assembly ensure that the front is aligned properly.
4.5.2 Battery life time
The battery life time is 1,500 hours (62 days) for continuous operation (without background
illumination). In the lower left corner of the display there is a symbol for the battery capacity.
This symbol appears if the battery voltage is too low. For instructions on batteries refer to
chapter 3 "Specications".
4.6 RS-232 interface
The CPG1000 has as standard an RS-232 interface. Only the interface converter oered
by WIKA may be used. The serial data transmission can be used for conguration, calibra-
tion and transmission of the instrument’s measured values.
WARNING!
The RS-232 interface must not be used in hazardous areas.
4.7 Connections
The CPG1000 uses a ¼ NPT male thread connection for its process connection. An
adapter on G ½ male thread is included in the scope of delivery. Dierent adapters may
be necessary for connection to the pressure reference standard. 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. Teon tape between the threads. The hose, lines and
ttings etc. must always be approved, as a minimum, for the working pressure which corre-
sponds to the pressure of the instrument. In addition, there must be no leaks during the
calibration process. If necessary, seal using Teon tape.
