Calibration Troubleshooting:
If the time to run for calibration is less than 4 seconds,
the cab console will display TIME TOO LOW.
Pressing the FUNCTION key will bring up the ENTER
TARGET AMOUNT screen. The target should be raised
to increase the calibration time. If the time is greater than
255 seconds, the cab console will display TIME TOO
HIGH. Pressing the FUNCTION key will bring up the
ENTER TARGET AMOUNT screen. The target should be
lowered to decrease the calibration time.
While rate calibration is running, one of four error mes-
sages may be displayed:
