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.

4. Design and function
4. Design and function
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 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

4.2.2 “WIKA-Cal - Cal-Template”).
4.3 Voltage supply
The internal Lithium-Ion battery, which can be easily charged with the battery charger supplied with the equipment, serves as
the voltage supply for the instrument.
To charge the CPH7000 rechargeable batteries, the mains plug of the power supply unit must always be plugged in to a mains
socket and accessible, so that one can always remove it from the mains socket without difficulty.
When using the electrical module, better results are achieved if the battery is not charged during the
measurement.
To avoid incorrect measurements, recharge the battery as soon as the battery indicator flashes. If the battery discharges too
much, the CPH7000 will automatically turn off.
The battery life is up to 8 hours in continuous operation (without backlighting, WIKA-Wireless is not active and the electrical
module does not supply voltage/current).
In the upper right corner of the display there is a symbol for the battery capacity. For instructions on batteries see chapter
4.10.3 “Battery symbol”).

4.3.2 Using the power supply unit
DANGER!
Danger to life caused by electric current
Upon contact with live parts, there is a direct danger to life.
▶Only use the power supply unit from WIKA supplied with the instrument!
▶If there is any visible damage to the case or the wiring, do not use the power supply unit!
▶Never install nor store the power supply unit in the following locations, as this can lead to a failure in operation:
■Places where there is strong humidity or condensation
■Outdoors
▶Disconnect the power supply unit from the mains supply when it won’t be used for a longer period of time.
▶The power supply unit is maintenance-free. It must not be opened (danger of electrical shock).
▶Before cleaning, disconnect the power supply unit from the mains supply. Do not clean with chemical cleaning
agents. Only clean with a dry cloth.
▶The power supply unit may only be used at an ambient temperature of 0 ... 40 °C (32 ... 104 °F) (humidity: up to
90 % relative humidity, non-condensing).
To avoid measurement uncertainties, use the CPH7000 only without a connected power supply unit.
The instrument is delivered with a charge level of 25 ... 50 % and should be fully charged once before being used.
The battery capacity status (charge state in %) is displayed shortly after the instrument is switched on.
When the power supply unit is connected to the CPH7000, the battery will be charged, even if the CPH7000 is
switched off.
The typical charging time of the rechargeable battery is < 5 h.
■When the power supply unit is no longer being used, the mains plug should be disconnected from the mains socket. Do not
leave the rechargeable battery connected to the power supply unit for longer than one day, since overcharging can shorten
its service life.
■Should the rechargeable battery still not be fully charged after 24 hours, contact the manufacturer. When not being used, a
fully charged battery will lose its charge over time.
■Extreme temperatures have an adverse effect on battery charging. As a result, the battery may first need to be either cooled
or warmed, as appropriate.
■When the battery is almost completely discharged, the message “low BAT” appears in the display.To avoid a data loss, the
instrument must be charged immediately.

In order not to put a strain on the case, it is recommended to hold the pressure connection on the CPH7000 by
means of an open-ended spanner.
The connections of the CPH7000 without pumping unit are provided with plugs. In order to maintain the IP
protection class, these plugs should not be removed.
4.6 Pump
CAUTION!
Physical injuries and damage to property and the environment
Improper handling of the pump can damage the process calibrator.
▶Do not use the pump when switched off.
The pump is a consumable. Regular maintenance is recommended after 100,000 pump cycles at the latest. Under normal use
conditions, this corresponds to a service life of 2 years.
Recommended procedure in vacuum range
1. Always pull out the piston rod until it stops.
2. Wait 5 seconds.
3. Carry out another pumping stroke until the desired pressure is reached.
4.7 Barometer
The barometric sensor is a very stable, high-accuracy absolute pressure sensor designed to measure the daily atmospheric
pressure.
It can be used to emulate gauge pressure using an absolute pressure sensor or to emulate absolute pressure using a gauge
pressure sensor. For a seamless absolute pressure emulation, a bi-directional measuring range with a start of measuring
range of -1 bar (-14.5 psi) is recommended.
4.8 Reference pressure sensor model CPT7000
For the CPH7000 process calibrator, a variety of reference pressure sensors with measuring ranges from 250 mbar (4 psi) up
to 10,000 bar (145,000 psi) and vacuum pressure sensors with an accuracy of 0.025 % FS are available. These sensors can
be replaced on the instrument very quickly and without using any tools.
When the process calibrator is switched on, the connected reference pressure sensor will be automatically detected.
