4.4 Integrated data logger

From the firmwareVersion 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 24V voltage supply to the terminals at the rear of the measuring instrument.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 specified 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!	GB
Do not change the alkaline batteries in hazardous area!	GB

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 accessible.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 "Specifications".

4.6 RS-232 interface

The CPG1000 has as standard an RS-232 interface.Only the interface converter offered byWIKA may be used.The serial data transmission can be used for configuration, calibration 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.Different 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.Teflon tape between the threads.The hose, lines and fittings etc.must always be approved, as a minimum, for the working pressure which corresponds to the pressure of the instrument.In addition, there must be no leaks during the calibration process.If necessary, seal usingTeflon tape.

5.Transport, packaging and storage

5.1 Transport

GB Check the precision 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 ...+70 °C

■■Humidity:0 ...90 % relative humidity (no condensation)

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 CPG1000 in its original packaging in a location that fulfils 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 film.

2.Place the instrument, 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 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.

condition (atmospheric).

Push the power button briefly to turn the instrument on.Push the button again to turn it off. After switching on the firmware version is indicated on the display for approx.1 second.

6.1 Normal operation

Turning on and off the background illumination: Press the Enter key.

Zeroing the display: Press and hold the ZERO key.

For absolute pressure gauge after pressing the ZERO key, the barometric reference value has to be entered.Use keys ▲ and ▼ to set the value. Confirm with ENTER.

As the calibration was realised with this value, it is recommended not to change the reference value set ex-works.

MAX/MIN: The CPG1000 stores the minimum and maximum pressure in the memory.If the MAX/MIN key is pressed once, the maximum pressure from the memory is displayed. If the MAX/MIN key is pressed again, the minimum pressure from the memory is displayed. After 2 seconds the instrument returns to normal operation.To delete the memory registers holding the values for MAX/MIN, hold the MAX/MIN key pressed for at least 2 seconds until the “CLr”message is displayed.The bargraph on the lower edge of the display indicates the present pressure proportional to the entire measuring range.

If aTARA value has been programmed for the CPG1000, the displayed pressure does not correspond to the actual pressure applied.

6.2 Setup and configuration

Press the CONFIG key to access the functions of the instrument which are adjustable by the user.Every time the CONFIG key is pressed, the display switches to the next function. As soon as a function is configured, press the Enter key to close the Configuration menu, or the CONFIG key to continue configuration.
