4 Design and Function
4.1 Description
With the Model CPH7600, Wally Box III, WIKA offers 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 fitted 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 different measurement tasks or calibrations,
regardless of external pressure and power supplies.

GB
6 Commissioning, operation
As soon as the calibrator is turned on, by pressing the ON/OFF key, it will go through a short selftest routine. During that routine, the display shows the current firmware version, auto-shutdown
status and the range of the internal pressure sensor. The calibrator requires a maximum of 5
minutes warm-up to reach its specified accuracy. Large changes in ambient temperature may
make a longer warm-up period necessary. Pressure ranges should be zeroed each time the
calibrator is started.
6.1 Calibrator display
The calibrator's display consists of two sectors: The menu bar (located along the bottom of the
screen) is used to access the menu system. The main display (the rest of the display) consists of
up to three sub-sectors for the measurement activities. These sub-sectors will be referred to as the
UPPER, MIDDLE and LOWER displays in this document.
Figure 1 shows the location of the different display fields, while are described in the following table.

6.1.2 Main menu Functionality
There are three options on the menu, "CONFIG", {active display} and "MORE". The main menu is
the 'home' for the menu display.
6.1.2.1 Setting the {active display}
The {active display} is displayed via the middle option in the menu in the main display. Pressing the
F2 button switches between the {active display}.
6.1.2.2 Setting the {active display} parameters
In order to set the {active display} parameters, select the "CONFIG" option and open the
configuration menu.
Here the "SELECT" option will switch between the available choices for each parameter. The first
parameter is "MODE". Since voltage, current and switch test modes all use the same leads, two of
these functions cannot be used concurrently. The ability to select certain functions is limited and
dependent upon what is already selected in the other display sector. The "NEXT" option is used to
change to the second parameter. Only the pressure modes have a second parameter.
Within any single display sector, the following modes are available:
P[1] = integrated pressure sensor
[EXT] = pressure with external pressure module
P[1] ST = switch test with integrated sensor
[EXT] ST = switch test with external pressure module
Current functions are only available on the lower display:
mA measurement = current measurement without power supply
mA w/24V = current measurement with power supply
mA Source = current source
mA sim = mA simulation using an external supply from the instrument under test
VOLT = voltage measurement
The following table shows which functions are available concurrently. An "--" in a column indicates
that the mode in the active display will not be available for selection if the mode in that row is in use
in any other display sector.

6.1.2.3 Accessing other menus In order to access further menus, select the "MORE" option in the main menu.
6.2 Using the backlighting The backlight is controlled by the "LIGHT" button.
6.3 Using the "ZERO" function
When the ZERO key is pressed, the calibrator will zero the active display, as long as a pressure
mode is selected and the pressure is within the zero limit. The zero limits are within 5 % of the full
scale range of the selected sensor. If the display indicates "OL" the zero function will not operate.
The ZERO key is only used for pressure.
6.3.1 External pressure module (not absolute)
When a pressure module is selected in the active display and the ZERO key is pressed, the
calibrator subtracts the current displayed reading from the output value. The zero limits are within
10 % of the full scale range of the selected sensor. If the display indicates "OL" the zero function
will not operate.
6.3.2 External pressure module (absolute)
When an external absolute pressure module is selected in the active display and the ZERO key is
pressed, the calibrator prompts the user to enter the barometric reference pressure. For this the
arrow keys can be used. The sensor port should be opened (vented) to atmosphere while
performing this procedure.
6.4 Other menu controlled functions
There are sub-menus that can be accessed through the "MORE" option of the main
menu. A sub-menu contains three options. The first option is unique to this function. The
second and third options of a sub-menu are always the same. The "NEXT" option leads
to the next sub-menu and the "DONE" option returns to home.
For the last sub-menu the "NEXT" option wraps around to home.
Note on naming:
If a 'sub-menu' has further subdivisions, from now on it will be referred to as {function} main menu.
The "CONTRAST" sub-menu for example will be referred to as the "CONTRAST" main menu.
Otherwise it will be referred to as the {function} menu.
