Description
With the model CPH6600 hand-held pressure calibrator, WIKA introduces a revolution in pressure calibration technol­ogy for the process industries. With this new instrument, the technician has access to a small, lightweight calibrator which can generate pressures of up to 10 bar through an integrat­ed, high-performance electrical pump. With the hand pump, up to 20 bar is possible.
The CPH6600 is only slightly larger than the model CPH6400 precision hand-held pressure indicator and weighs less than 1 kg. The housing is shaped and balanced so that it ts neatly in the operator's hand.
The pump is not the only key feature. The CPH6600 has a measurement uncertainty of ± 0.025 % FS for the built-in, isolated pressure sensor. The temperature compensation of the built-in sensor safeguards the measurement uncertainty for applications in the eld.
Hand-held pressure calibrator with integrated electri­cal pump model CPH6600
A connection for an external pressure module supports all WIKA pressure modules and thus enables larger measuring ranges. In addition, in combination with an external temperature sensor, simultaneous temperature measurement is also possible with the CPH6600. Additional functions, such as pressure switch tests and the display of the test items deviation in percent, increase the user-friendliness of the CPH6600.

Features
Temperature, current and voltage
A Pt100 resistance thermometer (RTD) is available as an option for measuring temperatures, with a measurement uncertainty of ± 0.2 °C. In addition the CPH6600 measures and simulates a 4 ... 20 mA loop current signal, can measure up to DC 30 V and comes with an internal DC 24 V power supply to power the transmitter being calibrated.
Display
The CPH6600 displays up to three calibration values. This means that the internal pressure sensor, an external pressure sensor, the temperature (from an optional temperature sensor) or electrical values (mA or DC V) can be displayed simultaneously. The display is a large graphical backlit LCD screen.
Pressure ranges
The CPH6600 can be delivered in dierent ranges of 2 bar, 10 bar and 20 bar relative as well as 2 bar and 10 bar absolute. The 20 bar versions come with a manual handpump.

Features
The new CPH6600 pressure calibrator has a whole range of useful functions. Switch tests can be performed via the internal or external pressure input. The test item error can be calculated from the CPH6600. A damping function is avail­able. Up to ve frequently used device settings can be stored and then retrieved at the touch of a button.
Compact and robust
The CPH6600, with its compact and rugged design, is powered by eight standard AA batteries. Through the Power Save function in the CPH6600, the battery pack has a life of about 300 pump cycles to 10 bar.

Special operating modes
Operating mode: pressure switch test
Use low volume hose if possible
Pressure switch
Pressure switch test:
With the pressure switch function, the CPH6600 can indicate the pressures at which the switch closes or opens. In addition, the hysteresis can be calculated.
In the switch test mode the display update rate is increased to capture changing pressure inputs quickly.
If required, the ambient or medium temperature can be measured with an external Pt100 resistance thermometer simultaneously.
Operating mode: calibrating transmitters and percentage error function
Calibrating transmitters:
With the mA measurement function, the 4 ... 20 mA output of the instrument which is currently being caibrated can be read. This can be done in two ways.
1) Passively – the device under test generates 4 ... 20 mA directly. This can be read on the calibrator.
2) Actively – the calibrator supplies a loop power of DC 24 V to the device under test to power the device while reading the resulting 4 ... 20 mA signal.
The calibrator features a special function which can calcu­late the error in the pressure value from the mA value as a percentage of the 4 ... 20 mA loop span. The %-ERROR mode uses all three screens and has a special menu struc­ture. It is possible to display pressure, mA and %-error simultaneously.
Example:
A pressure transmitter, that is to be tested, has a measur­ing range of 2 bar and outputs a corresponding 4 ... 20 mA signal. The user can programme in a 0 ... 2 bar pressure span into the calibrator and the calibrator will then calculate and display the deviation or the error value from the 4 ... 20 mA output. This is achieved without any manual calculation, which is also an advantage when a specic pressure can only be set with diculty using an external pump.

CPH6600 dirt trap
The CPH6600 should only be used with dry and clean test items. Soiling of the integrated pump, for example, through contaminated test items, can cause a defect or require the pump to be cleaned.
By using the dirt trap specically developed for the CPH6600, contamination of the intrgrated pump can be prevented.
Using the dirt trap
The dirt trap is attached, hand-tight, to the calibrator's pressure connection. The seal is made by the O-Ring incorporated into the dirt trap's 1/8 NPT male thread. The maximum working pressure is limited to 35 bar.
The test item is mounted on the top of the dirt trap, using a suitable sealing method. The connection to the test item is usable universally as 1/8 NPT or 1/8" BSP. Use a ⅞" or 23 mm spanner on the hex of the upper pressure port to connect the test item with the dirt trap.
Hand-held pressure indicator with mounted dirt trap
As soon as either moisture or dirt can be seen in the transparent chamber, the dirt trap should be removed and cleaned.
Once the upper dirt trap connection has been unscrewed, the transparent acrylic chamber and the O-ring can be removed and cleaned with a clean cloth.
