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.

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 dierent 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

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 specic pressure can
only be set with diculty 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 specically 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.
