Boom Angle
Bias And Slope Sliders Explanation
Always start at a high boom angle and adjust the Bias to achieve actual load on hook. The Bias slider will move
the entire Calibration Target UP or DOWN as shown below.
I.E. - Actual load on hook is 8,000 lb (3 629kg) and the Calibration Target is at 6,500 lb (2 948kg) , increase the
slider value until the Calibration Target of 8,000 lb
(3 629kg)
is achieved.
Boom down to 20 degree boom angle and adjust the Slope to achieve the actual load on hook. When the
Slope is adjusted, the Calibration Target is tilted. At low boom angles, the pressure applied to the transducers
is greater than the pressure applied at a high boom angles. The system uses a multiplier when generating the
Calibration Target so there is more effect at low boom angle when using the Slope adjustment than at high boom
angles as shown below.
When adjusting the Slope, return to the high boom angle and check the weight. Adjust the Bias again, if
necessary, then return to the low boom angle and check the weight. As the Bias is adjusted, the pivot point will
move accordingly. This procedure may need to be repeated several times to achieve the actual load on hook
at both high and low boom angles.
