Distance Calibration Factor
The distance calibrate pad (DISTANCE CAL) selects the distance calibrate function. The distance calibrate factor is a correction factor for variation in ground speed measurement hardware. The minimum and maximum for the distance calibration factor is 135.0 - 165.0 meters for International Measure operation and 450 - 550 feet for U.S. Customary operation.The distance calibration factor may be changed by holding the distance calibration keypad down for five seconds. The value may be entered either directly, using the DIGIT SELECT and DIGIT SET pads, or by following the calibration procedure.Calibration Procedure
To begin the calibration procedure, measure a 150 meter course, for International Measurement, or use a 500 foot course, for U.S. Customary operation. Place a marker at each end of the course.With the machine 10 meters (33 feet) behind the first marker, hold the DISTANCE CAL pad down for five seconds to get an all zero display. Start the machine in motion.When the machine reaches the first marker, depress the DISTANCE CAL pad once to start the calibration procedure. During the calibration procedure, four dashes will appear on the display.When the machine reaches the second marker depress the DISTANCE CAL pad again. The new distance calibration factor will be displayed and saved.As in the manual entry mode, an invalid distance calibration will not be saved and will cause the yellow distance calibration pad LED to flash. If the distance calibration pad is inadvertently modified, the values 150 for International Measure, or 500 for U.S. Customary may be entered directly, using the DIGIT SELECT and DIGIT SET pads.Ground Speed
The ground speed pad (GROUND SPEED) selects the ground speed display function. The displayed ground speed is either the track speed, or if a ground speed sensor (radar unit) is present, it is true ground speed. The minimum displayed ground speed is either 1.6 km/h or 1.0 mph. Speed below 1.6 km/h (1.0 mph) results in a zero being displayed.Percent Slip
Touch and release the percent slip pad (% SLIP) to display the percent of track slippage. This reading is based on the true ground speed compared to track speed.The range of displayed slip value is 0% to 100%. If calculated slip value is negative, a "-0" is displayed.Due to the characteristics of the ground speed sensor, (characteristics necessary for reliable ground speed measurement over varying terrain), the measurement of slip does not begin until the track speed is 1.6 km/h (1.0 mph).If the ground speed sensor (radar unit) is not connected, or is connected but not working properly, "ERR" is displayed while the % SLIP pad is depressed.To calibrate the % SLIP function, run the machine lightly loaded so that no track slip is present. During lightly loaded operation, hold the % SLIP pad down for five seconds. The display will go to zero. This action will calibrate the % SLIP reading to "zero" and compensate for possible mechanical or electrical tolerances in the drive train and monitoring system. If the % SLIP pad is held down for five
