4.4.6 P2AHH
Horizontal distance between centre of auxiliary hoist drum and boom base
pin. If the drum is mounted on the boom, this dimension is 0.00 If there is no
auxiliary drum enter 0.00
4.4.7 P2AHV
Vertical distance between centre of auxiliary hoist drum and boom base pin.
If the drum is mounted on the boom, this dimension is 0.00. If there is no
auxiliary drum enter 0.00
4.4.8 B
The distance perpendicular to the boom between the boom base pin and the
lift cylinder top pin. When the boom is horizontal, if the boom base pin his
higher than the lift cylinder top pin, the distance is positive. If the boom base
pin is below the lift cylinder top pin, the distance is negative.
4.4.9 BORE DIAMETER
The inside diameter of the lift cylinder in inches or centimetres. If this
dimension is not precisely known, the hook load displayed after calibration
could be wrong. It can however be corrected by the LOAD ADJUST menu.
4.4.10 ANNULAR GAIN
The annular gain is the ratio between the full side and the rod side of the lift
cylinder. The diameter of the rod squared divided by the bore diameter
squared minus one equals the value required. ie:-
