2. Short overview / 3. Safety

2.2 Description

The model CPH7000 process calibrator is a battery-powered, precise, portable calibrator for the on-site calibration and checking of analogue pressure measuring instruments, pressure transmitters and process transmitters. Furthermore, pressure switches can be checked and the switch point determined. With the CPH7000, not only can transmitters be checked, but also simulated and tested.

The integrated hand pump (optional) enables you to generate a pressure of up to 25 bar (360 psi). This pressure can be measured by means of an integrated pressure sensor (optional, available only in conjunction with the pump). For pressure ranges of -1 ... 10,000 bar (-14.5 ... 145,000 psi), the model CPT7000 external precision pressure transmitter is available. In conjunction with the data logger, it is also possible to carry out a leakage test in a very simple manner.

3. Safety

▶

When using the electrical module, set the measurement type first and then connect the connection cables.

▶

Only tighten the vent valve by hand, as it is a needle valve. Tightening with excessive force can result in a damage of the needle valve or the sealing.

▶

Inspect the test leads for damaged insulation or exposed metal. Check the continuity of the leads. Damaged test leads should be replaced before using the process calibrator.

▶

When using test probes, keep fingers away from the test probe contacts. Keep your fingers behind the test probes' finger guards.

▶

First connect the common lead, and then the live lead. When disconnecting, remove the live test lead first.

▶

Disconnect test leads before changing to another measurement or source function.

▶

When the battery indicator lights up red, load the rechargeable battery of the CPH7000, in order to avoid an incorrect display or a data loss.

▶

To avoid any damage to the process calibrator or to the inspection equipment, always use the proper connection cable, function and area for the respective measuring application.

▶

The switch valve can be switched from positive pressure to vacuum or from vacuum to positive pressure only in depressurized state.

▶

Only use the accessories specified and authorized by WIKA.

▶

If pressure is applied over a long period of time, the pump can be damaged.

▶

Only use pressure sensors model CPT7000! The use of other pressure sensors can result in the destruction of the measuring instrument and of the pressure sensor.

▶

Make sure that the internal sensor is not overloaded by the pump.

The electrical module can generate max. 30 mA and DC 24 V and measure max. 30 mA and DC 30 V. With the integrated pump, pressures from -0.85 ... +25 bar (-12.3 ... +360 psi) can be generated.

Any use beyond or different to the intended use is considered as improper use.

4. Design and function

simulated and tested.

The CPH7000 can be operated by means of a clearly structured touchscreen. The integrated rechargeable battery allows the CPH7000 to be used daily in the field.

4.1 Design

The CPH7000 can optionally be equipped with an integrated reference pressure sensor as well as an integrated manual pressure generation (pressure sensor only available in conjunction with pressure generation), with which pressures from

-0.85 ... +25 bar (-12.3 ... +360 psi) can be generated. A pressure connection enables a calibration item (test item) to be connected to the reference pressure sensor as well as to the integrated pressure generation of the CPH7000. The integrated pump (optional) allows you to generate different pressure ratings and thus to carry out a calibration. An external separate pressure generation up to 25 bar (360 psi) is thus not necessary.

Transmitter output signals can simultaneously be measured via an electrical module, thus enabling the simultaneous display of the reference and test item value on the screen. This allows a complete transmitter calibration to be carried out with just the CPH7000. In addition to the integrated sensor, it is also possible to connect up to two external reference pressure sensors to the CPH7000, thus enabling the measurement of pressure also in other pressure ranges or differential pressure. Communication between CPH7000 and pressure sensors is digital.

The ambient atmospheric pressure is measured via an integrated barometric reference which can optionally be integrated in the case. This also enables gauge pressure sensors to be converted into absolute pressure. The ambient conditions (temperature and humidity) can be measured by means of an additional external atmospheric module. To the connection for the atmospheric module, it is also possible to connect a temperature probe Pt100.

4.2 Functions and data transfer with the WIKA-Cal calibration software

The calibrator offers the possibility to create calibration routines quickly and easily, but also to carry out preconfigured calibration routines. An integrated memory allows the recording of logger cycles as well as calibrations on site. The completed calibration processes can be transmitted to a PC via WIKA-Wireless.

As soon as a connection exists over WIKA-Wireless, it can communicate with the WIKA-Cal calibration software from version

1.0.66. Data can also be transferred using Windows Explorer. A complete paperless transmitter calibration can be carried out using the CPH7000 and WIKA-Cal.

As the CPH7000 features an electrical module, the hand-held also has to be set up as a multimeter.

Compatibility between the CPH7000 process calibrator and the WIKA-Cal evaluation software is only possible with the following firmware versions and higher. CPH7000: 1.1.4 or higher WIKA-Cal: 1.0.82 or higher
