Allow the crane to settle (monitor the live angle and pressure readings shown here) and
once the readings are stable press
“

” to record the calibration point. Repeat this
procedure for each calibration point in turn as prompted starting with all angles for
length 1 then length 2 etc. until all lengths and angles have been recorded. At the end
of each length sequence the system will pause to automatically to save the calibration
data up to this point. If the calibration is exited at this stage then the system will display
the following screen when the no load calibration is reselected, allowing the procedure
to continue from the same point without the need to redo the completed section.
Note the incomplete calibration will be lost if the duty is changed before returning to
the no load calibration procedure.
When the final calibration point is accepted the i4500 will automatically save the data
and display the following confirmation screen:
Press “

” to return to the main calibration menu.
To exit the no load calibration at any point prior to completion press “

” then confirm
the action by pressing “

” .
Before proceeding with additional calibration work check the overall performance by
moving the unloaded hook around the working envelope; i.e. high/low angles and
long/short boom. If an unacceptable variation in displayed hook weight is seen then
check geometric dimensions entered earlier, re‐calibrate the no load pressure map
using more calibration angles and lengths, or proceed to add load adjustment, offset
and/or correction calibrations. Always check results at this stage after booming up.
Boom down can be checked after the full calibration is completed.
For the definition of required accuracy refer to national and international standards
applicable where the crane is in use eg SAE J159 in USA or EN13000 in Europe.
