Load Cell Wiring
Figure 2-3 shows the load cell terminal strip wiring for the WILDCAT scale.
Serial Port Connections
The WILDCAT scale provides a bi-directional RS-232 port to be used to send data to or
receive commands from a computer, printer, or other serial device. The following chart
(Table 2-1) describes the pin configuration of the 9-pin D-Sub female connector on the
side of the terminal (indicator) of the WILDCAT scale. The maximum recommended
cable length for RS-232 is 50 feet (15 meters).
NOTE: Bi-directional capability
was added in version 2.0
software. Previous versions did
not provide ASCII input
commands.
Table 2-2 shows the ASCII commands that may be used to communicate with the
WILDCAT scale via the serial port. A more complete explanation is given in Appendix 3.

WARNING
ONLY PERMIT QUALIFIED PERSONNEL TO SERVICE THIS EQUIPMENT.
EXERCISE CARE WHEN MAKING CHECKS, TESTS AND ADJUSTMENTS
THAT MUST BE MADE WITH POWER ON. FAILING TO OBSERVE THESE
PRECAUTIONS CAN RESULT IN BODILY HARM.
The WILDCAT scale is calibrated at the factory. Functional programming is also
completed at the factory, so that the WILDCAT scale is ready to use right out of the box.
There is no need to change any of the softswitch parameters or to calibrate the scale.
However, for commercial purposes (legal for trade), the WILDCAT scale must be
calibrated using certified test weights. All operational changes and calibration can be
performed using the scale keyboard.
Serial Port Connections
The programming mode of the WILDCAT scale consists of main blocks (F1, F2, and
F3), each containing sub-blocks (F1.1, F1.2, and so on.) An overview of the
programming mode is shown below.

Entering and Configuring Program Blocks
Once the [F1] prompt is displayed, use the PRINT key to enter the block. Use the
FUNCTION key to skip to the next block. Use the ZERO key to go to the previous block.
Once PRINT is pressed, the configuration advances to the first parameter in the F1
program block. The display shows the sub-block number and the current value setting.
Press PRINT to accept the value and advance to the next sub-block or press the
FUNCTION key to toggle through the choices until the desired selection is displayed.
After the desired selection is displayed, press PRINT to accept the value. Continue this
procedure throughout the setup routine until all required changes have been made.
At the end of all the program blocks, there is a SAVE program block. In this block, you
can use the FUNCTION key to select SAVE, ABORT or DEFAULT. When the desired choice
is displayed, press PRINT. The scale exits the programming mode after the selection.
Sealing the Enclosure
(Legal for Trade)
SAVE The WILDCAT scale will save all the changes you have made to the program
blocks and then exit setup.
ABORT All changes will be discarded and the original programming will remain.
DEFAULT All blocks, except those steps denoted by *s in Table 3-1 are reset to the
factory defaults.
After calibration is complete, setup step F1.4 should be programmed as a “O” to
eliminate accidental changes to the calibration values. After programming is complete,
remove the setup jumper CAL (Figure 3-2) to prevent setup access. Close the enclosure,
tightening all four screws on the rear cover. Install the two plastic plugs over the bottom
screws and seal the enclosure as shown in Figure 3-3.

Calibration
When the WILDCAT scale is used in legal-for-trade commercial applications, it must be
calibrated with certified test weights to the capacity and increment size shown on the
data plate. The capacity and increment size is selectable in the programming mode in
sub-block F1.2. Calibration is also completed in sub-block F1.2.
Gravity Adjustment
The WILDCAT scale terminal has built in compensation to allow factory calibration with
destination correction capabilities to compensate for variances caused by gravitational
forces. If the WILDCAT scale is subjected to a different gravitational force at its
destination location, this can be compensated for electronically by adjusting the geo
value. The GEO value has 32 settings. The GEO value for any world location can be
found in the GEO value table in Appendix 4 as long as the geographical coordinates
and elevation above sea level are known. This value is programmed in the Scale block
when prompted for [GEO xx].

Voltage Checks
AC Power Test
Using a Multi-meter, check the AC input power. Input power must be within -15% and
+10% of the nominal AC line voltage.
Controller PCB Input Voltage Test
Confirm the AC adapter is outputting a voltage of at least 9 VDC. If the WILDCAT scale
has power and the Controller PCB does not function properly, replace the PCB.
Check Battery Voltage(Battery-powered units)
If the WILDCAT scale does not respond by pressing the PRINT key for approximately 3
seconds, the battery pack may be completely discharged. Install a new set of six “D”
cells and retest.
RS232 Serial Output Test
Use the following test procedure to determine whether the RS232 serial port is
operational.
• Remove power and disconnect the data cable from the WILDCAT scale.
• Set the volt meter to read 20 volts DC.
• Connect the red lead to pin 3 of the WILDCAT serial port connect the
black lead to pin 5.
• Apply power. The meter should read as follows:
• In Demand mode, the meter should read between -5 and -15 VDC with no
fluctuation.
• To test the Demand output, press the PRINT key on the WILDCAT scale and the
display should fluctuate between -5 volts to +5 volts for the duration of the
transmission, then become stable again. This indicates the terminal has
transmitted data.
• In Continuous mode, the meter should fluctuate between -5 and +5 VDC
continuously. The constant fluctuation on the meter display indicates the
scale/terminal is transmitting information.

Shift Test
Chapter 4: Maintenance and Troubleshooting
Parts Replacement and Adjustments
A shift test verifies that the scale weighs correctly irrespective of load placement. If the
scale does not pass the shift test, verify the overload stop gaps before replacing the load
cell. No adjustment for the shift is possible. If the scale does not pass the shift test, the
load cell must be replaced.
For NTEP and Canadian Weights and Measures tests, use weights equal to 1/2 the
scale’s capacity. Place the test weight sequentially at each of the positions A, B, C, D
and E as shown in Figure 4-5. These positions are the centers of the four quadrants of
the platform and the center of the platform. Note the terminal’s reading of the weight at
each position. The difference between any two positions in the shift test cannot exceed
the tolerance shown in Table 4-4.

Mode Output
Demand mode output occurs when a print request is received form the PRINT push
button. The line format, baud rate, character length, and parity are selectable in the
programming mode.
Demand mode output is blocked when the scale is “in motion” or when the weight is
below 20d of gross weight or over capacity. When one of those situations occurs,
the print request is ignored and is not buffered. Zero must be captured at powerup
before a demand mode output can occur. After one output, the WILDCAT scale must
see motion before it will send data again.

Appendix 2: Continuous
Mode Output
The continuous output format is output as the display is updated (approximately 7
times per second). The format is fixed except for baud rate, data bits, stop bits,
parity, and the selectable checksum character. The continuous output mode provides
compatibility with METTLER TOLEDO products that require real-time weight data (for
example, Models 8624, 9323, 9325, and other accessories).
Continuous data output at a 1200-baud rate will slow the display update rate. Use
4800 baud or faster to maintain the maximum update rate.
The continuous output includes status bytes that indicate the operating conditions in
the terminal.

METTLER TOLEDO WILDCAT Scale Technical Manual
Appendix 3: ASCII Input
Commands
Beginning with software version 2.00, the WILDCAT scale has the ability to receive
certain ASCII characters via the serial port to perform simple keyboard functions.
Previous versions of software did not have this capability. The software version can be
viewed at power up.
The ASCII input commands will operate when the serial port is programmed for either
demand output or continuous output. The input character format must be the same as
the data output format selected in setup including baud rate, data bits, parity and stop
bits. The remote commands are subject to the same restrictions as the keyboard
equivalents. For instance, tare, zero and print commands will only operate if sent when
there is no motion on the scale. When sending multiple commands, there must be a
time delay of at least one-half second (500 milliseconds) between each remote ASCII
command character.
These ASCII commands duplicate the front panel functions. Note that all characters are
uppercase and no control characters such as <CR> (carriage return) or <LF> (line feed)
need to be sent. If they are sent, they will be ignored. All ASCII characters other than the
ones listed below will also be ignored.
The following commands are recognized by the WILDCAT scale when the output mode
is programmed as either demand mode or continuous output.
Command Function Description
C Clear Clear tare value
T Tare Performs a pushbutton tare
P Print Transmit data or set print bit in continuous output
S Print Transmit data or set print bit in continuous output
Z Zero Zero the scale (if within range and no-motion)
