Wally Box III
Wally Box III, model CPH7600
Description
General information
With the model CPH7600, Wally Box III, WIKA oers a further
development of the well-known Wally Box I and Wally Box II.
The Wally Box III is a compact, portable pressure calibrator, which has been designed for mobile use as well as for
stationary workshop and laboratory testing. A special feature
of this test instrument is that it is tted with two independently-operating pressure systems.
One pneumatic system is designed to be supplied from an
external pressure supply, while the supply pressure of the
second system is generated by the integrated electrical
pressure generation. This enables the user to perform dierent measurement tasks or calibrations, regardless of external
pressure and power supplies.
Accuracy
The Wally Box III provides an accuracy of 0.025 % of reading
±0.01 % FS for the built-in pressure sensor. The temperature
compensation of the built-in sensor safeguards the accuracy
for applications in the eld. Readings can be displayed in one
of 13 standard units.
Features
With the Wally Box III, not only accurate pressure measurements are possible, but also exact current and voltage
measurements, as well as a DC 24 V supply for test items.
Pressure values and electrical measured values are simultaneously shown in the display.
The calibrator is integrated into a robust, as well as dust and
watertight transport case. Thus the mobile pressure calibrator
is particularly suited to use in harsh industrial environments.
A ow diagram on the front panel gives information on the
connection of the individual pneumatic components.
With the built-in NiMH rechargeable battery, a battery life of
50 hours or 125 pump cycles up to 20 bar is guaranteed. The
external universal power supply is designed for an operating
voltage of AC 100 ... 240 V.

Features
Pressure supply
The Wally Box III enables the supply of pressure in two
dierent ways. The rst is an integrated electric pump from
-0.8 ... +20 bar. The second possibility is the connection of
compressed air up to 8 bar, which allows the user to control
pressures up to 7 bar via a ne adjustment.
The advantage for the user of these two dierent pressure
supplies is that the compressed air supply of a workshop can
be used, but also, for applications in the eld, the air supply is
ensured via the integrated electrical pressure generation.
Current and voltage
In addition to pressure, the Wally Box III measures and
simulates also a 4 ... 20 mA current loop signals, can
measure up to DC 30 V and comes with an internal DC 24 V
voltage supply to power the transmitter being calibrated. The
DC 24 V voltage supply is switchable for transmitters with mA
as well as V output signal.
Display
The Wally Box III can display up to three calibration values
simultaneously. This means that the internal pressure sensor,
an external pressure sensor and electrical values (mA or V)
can be displayed simultaneously. The instrument has a large
graphic LCD display with backlighting.
Pressure ranges
The Wally Box III features an integrated reference pressure
sensor with a measuring range of -0.8 ... +20 bar. Since the
accuracy is specied in % of reading, the Wally Box III lends
itself to the calibration of test items with dierent measuring
ranges up to 20 bar.
Each pressure range can be accurately generated with the
integrated electric pump at the touch of a button, or accurately controlled with external compressed air. The ne adjustment is made with the integrated volume slide.
Functions
The Wally Box III has a complete range of useful functions.
Switch tests can be performed via the internal or external
pressure input. The deviation of the test item is directly calculated and indicated on the display. A damping function is
available. Up to ve frequently-used instrument settings can
be stored and retrieved with the touch of a key.
Similarly, high-accuracy model CPT6100 external pressure
sensors can be connected via a sensor cable. This allows
accuracies of up to 0.01 % to be achieved.
Robustness
The Wally Box III consists of a calibrator, which is built into
a rugged service case. With this design, the Wally Box III is
suited to extremely harsh operating conditions.

Calibrating transmitters
With the mA/V measuring function, 4 ... 20 mA output and
0 ... 30 V output can be read from the test item. This can be
done in two ways.
1) Passively – the test item generates 4 ... 20 mA or
0 ... 30 V directly. The value is read by the calibrator.
2) Actively – the calibrator supplies a voltage of DC 24 V
to the test item whilst reading the resulting 4 ... 20 mA or
0 ... 30 V 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 span. The %-error mode uses
all three screens and has a special menu structure. It displays
pressure, mA and %-error simultaneously.
Example:
A transmitter to be tested has a measuring range of 20 bar
and outputs a corresponding 4 ... 20 mA signal. The user can
program in a 0 ... 20 bar pressure span into the calibrator
and the calibrator will then calculate and display the devia-
tion or error in a percentage value of the 4 ... 20 mA output.
This is produced without the need for any manual calculation,
which is also an advantage if it is dicult to set an accurate
pressure using an external pump.

as possible

Dirt trap
The Wally Box III should only be used with dry and clean test
items. Soiling of the integrated pump, for example, through
contaminated test items, can lead to faults on the pump or
require the pump to be cleaned.
By using the dirt trap specically developed for the
Wally Box III, contamination of the integrated pump can be
prevented.
Using the dirt trap
The dirt trap is attached, hand-tight, at the pressure connec-
tion of the calibrator. Sealing is achieved via the O-ring tted
on the ⅛ NPT male thread of the dirt trap. The maximum
working pressure is limited to 35 bar.
The test item is mounted to the upper connection of the dirt
trap, using a suitable sealing method. The connection to the
test item is usable universally as ⅛ NPT female or ⅛ BSP
female. Use a ⅞" or 23 mm spanner on the hex of the upper
pressure port to connect the test item with the 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-rings can be removed
and cleaned with a clean cloth.

WIKA-CAL calibration software
Easy and fast creation of a high-quality calibration
certicate
The WIKA-CAL calibration software is used for generating
calibration certicates or logger protocols for pressure
measuring instruments and is available as a demo version for
a cost-free download.
A template helps the user and guides him through the
creation process of a document.
In order to switch from the demo version to a full version of
the respective template, a USB key with the template has to
be purchased.
The pre-installed demo version automatically changes to
the selected full version when the USB key is inserted and
is available as long as the USB key is connected to the
computer.
