F44: Low Pressure
This message indicates that the pressure is too low (0.5V or less) at a measurement point. Check -
DIAGNOSTICS / SENSORS to check the pressure.
F45: High Pressure
This message indicates that the pressure is too high (4.5V or more) at a measurement point. Check -
DIAGNOSTICS / SENSORS to check the pressure.
F46: Check Elev
This message indicates that the elevation switch opened more than once during calibration lifting. -
F47: Check Elev
This message indicates that the elevation switch closed more than once during calibration lowering. -
F48: Bad Pressure
This message is given if the pressure sensor output (P4-2) is out of range at the start of calibration. -
The height sensor output must be between 0.5V and 4.5V. Check DIAGNOSTICS / SENSORS to see
the output. A reading of 0V or 5V is probably due to a wiring problem.
F52: Too Few!
This message indicates that not enough measurements were recorded during calibration lifting or -
lowering.
F98: Out of Range
This message indicates that the “fine tune” calibration is unacceptable. This probably is due to the -
wrong load being in the platform (i.e: specifying “EMPTY” if the platform is loaded, or the other way
round) or (Having the incorrect pressure transducer installed).
During calibration the following information messages may appear:
Caldate:
This message is prompting for the date to be entered; it is stored to identify when the machine was -
calibrated. The last calibrate date can be viewed in DIAGNOSTICS / LOG. Press LEFT & RIGHT to select
the flashing digits. Press UP & DOWN to change the flashing digits. Press ENTER when the entry is
complete. IMPORTANT: The date 00/00/00 is not allowed!
Finished
This message confirms that calibration is complete and successful. -
Lift Empty
This message is displayed while the platform is being raised to the next measurement height, when an -
EMPTY platform is being calibrated.
Lift Loaded
This message is displayed while the platform is being raised to the next measurement height, when a -
LOADED platform is being calibrated.
Lifting
This message is displayed while the platform is being raised, during HEIGHT-only calibration. -
Lower Empty
This message is displayed while the platform is being lowered to the next measurement height, when -
an EMPTY platform is being calibrated.
