Menu 07 – Radius/Moment
This menu is used to calibrate the radius and moment of the boom.
1. Press the
Next
or
Prev
buttons until
“07 Radius Moment”
appears in the information window
at the right.
2. Press the
07 Radius Moment
button will give you a chance to enter an existing calibration in
the edit mode, or start a brand new calibration. Press the
Yes
button to delete old calibration
information and start a new calibration.
3. Press the
07 Radius/Moment
button will enter the Tare Load screen. Enter the weight of the
downhaul. When entering the Tare load in the calibration routine, adding 100 pounds (0.1) to
the actual weight will guarantee a slightly positive load reading in all operating configurations.
4. Up to seven Radius Moment points may be stored and must include:
a. Boom fully retracted.
b. Boom fully extended.
NOTE: Intermediate points should include individual boom sections extended and/or other individual
boom sections that stop telescoping as the boom is extended. Some booms will exhibit a deflection or
droop when nearing full extension.
NOTE: This is due to the design and fitting of wear pads inside the boom, which allows sections to
hang on each other when nearing full extension. Though this has little effect on main boom radius
accuracy, the radius of a fly or jib may be affected. It is recommended to add an extra calibration point
at 90% of the boom extension.
