6.17. Alter Calibration Data
This function is used for manually copying and restoring the calibration data. This should be done
after completing system calibration. When sensors are calibrated, calibration values are recorded (low
calibration value with corresponding sensor raw counts, and high calibration value with corresponding
raw counts). These values are described as “Raw Lo”, “Cal Lo”, “Raw Hi” and “Cal Hi”. These values
can be re-entered manually if calibration data is lost (for example, due to replacement of controller
PCB) and can also be used for trouble-shooting (invalid calibrations can be easily identified). This
data can be restored into the system simply by keying in the values without the need to luff the boom
or lift test loads.
The following procedure covers instructions on how to view and copy (manually, using pen and paper),
and also restore the calibration data for service records by accessing function code F-xx “Alter
Calibration Data”.
If the system needs to be re-calibrated, for example, due to replacement of parts and/or sensors,
these data can be restored into the system simply by keying in the values without the need to luff the
boom or lift test loads.
View and Copy Calibration Data
•
Access function code “Alter Calibration Data” by selecting it in calibration mode and pressing
the ENTER key.
•
The screen will then show “An1” (Angle channel) on the screen. This is the default sensor that
comes up on the screen. Pressing the Up/Down arrow keys will scroll through the various
sensors, but only the following functions need to be copied (for a tension based twin winch
strut boom crane):
o
Function
Description
o
An1
Angle
o
Ld1u
Load 1 (or Main Load) Up
o
Ld1d
Load 1 (or Main Load) Down
o
Ld2u
Load 2 (or Aux Load) Up
o
Ld2d
Load 2 (or Aux Load) Down
•
Once a function is selected, press the ENTER key again to access the calibration data for the
particular sensor as follows:
o
Calibration data
Description
o
Lo_r
Raw Counts (Low)
o
Lo_c
Calibrated Data (Low)
o
Hi_r
Raw Counts (High)
o
Hi_c
Calibrated Data (High)
•
A table similar to the one below can be used to record the calibration data of the sensors.

Restoring Calibration Data
Restoring the calibration data requires entering the calibration data copied from the procedure above
using the same function code.
