Wally Box III
Description
General information
With the model CPH7600, Wally Box III, WIKA oers 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 dier­ent 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
dierent 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 dierent 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 specied in % of reading, the Wally Box III lends itself to the calibration of test items with dierent 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 dicult to set an accurate
pressure using an external pump.

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 specically 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
certicate
The WIKA-CAL calibration software is used for generating
calibration certicates 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.
