Pick up the calibration load again and check that the display shows the correct amount. Allow 9.
the load to adjust for a few seconds if necessary.

Remember that the load will actually show the boom moment plus the load, because the system has
not yet been calibrated for boom moment. A good way to check this is to read the load when the
load is set down, and then take another reading when the boom is raised. Subtract the 1st unloaded
number from the loaded number, and the result should be very close to the exact weight.
In cases where the proper result is not being achieved and the geometry dimensions are correct,
by re-entering the pressure calibration routine and selecting “No” when asked to perform piston
calibration, the cylinder bore size may be adjusted to achieve the proper weight. Be aware that any
changes made will have a dramatic effect on the displayed load.
