METTLER TOLEDO WILDCAT Scale Technical Manual 4. Reinstall the rear cover over the batteries and press into place. 5. Test for proper operation. The operating time for a new set batteries depends on how the scale is used. Estimates (without backlight) are shown below. Using the backlight feature reduces battery life. Operation Continuous use 8 hours per day Battery Life 400 hrs (Approximately 17 days) 500 hrs (Approximately 3 months) Keyboard Replacement 1.
Chapter 4: Maintenance and Troubleshooting Parts Replacement and Adjustments Load Cell Replacement 1. Remove power by removing the six “D” size batteries from the rear battery compartment and/or disconnecting the AC power adapter. 2. Remove the four screws securing the front and back halves of the cover. 3. Disconnect the keyboard tail from the Controller PCB and set the front cover aside. 4. Disconnect the load cell wiring from the J4 terminal strip on the Controller PCB. 5.
METTLER TOLEDO WILDCAT Scale Technical Manual Overload Stop Adjustment 1. The overload stops must be checked and reset if the top or bottom frame or the load cell has been replaced. 2. Remove the stainless steel platform from the base. 3. Using the proper size feeler gauge, check all six overload stops as shown in Figure 4-3. The correct gap measurements can be found in Table 4-3. 4. If the gaps are not set properly, proceed to the following steps. 5. Loosen the overload screw jam nuts.
Chapter 4: Maintenance and Troubleshooting Parts Replacement and Adjustments Shift Test 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.
METTLER TOLEDO WILDCAT Scale Technical Manual Power-Up Sequence Upon power up, showing all numbers 0-9 checks the display, and a diagnostic self test is performed on the memory and microprocessor. An error message is displayed if any component fails the test. The program number [125362] is shown next, followed by the revision [Sr. 2.00]. If everything tests okay, the WILDCAT scale will show [ 0.00] on the display. The power-up sequence requires a few seconds to complete.

Chapter 6: Appendices Appendix 1: Demand Mode Output 6 Appendices Appendix 1: Demand 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.
METTLER TOLEDO WILDCAT Scale Technical Manual Single Line – Gross, Tare, Net Weights Single-line gross weight format is output if no tare weight has been taken.

METTLER TOLEDO WILDCAT Scale Technical Manual 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).

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.
Chapter 6: Appendices Appendix 4: GEO Codes Appendix 4: GEO Codes Use the following Geo Codes if you relocate the WILDCAT scale to a location other than the original location where it was calibrated.
