The display will ask to confirm:
 The configuration or attachment to calibrate.
 The selected hoist
 The number of parts of line
 The hook block or ball weight
Step 1 of 3: Fully retract the boom to the minimum
length and position the boom above the
recommended angle. Adjust angle ending with a
downward motion and allow sufficient time for the
pressures to stabilize and confirm.
This step requires a load of 50 to 100% of rated
capacity with the boom fully extended at 20° or
minimum allowed by load chart in this configuration.
The display will ask to confirm:
 The configuration or attachment to calibrate.
 The selected hoist
 The number of parts of line
 The hook block or ball weight
Step 1 of 4: Lift a known weight and position boom
past the recommended angle. Adjust angle ending
with a downward motion, allow pressures to stabilize
and confirm the total weight (known weight +
estimated cable weight + slings + pins).
Step 2 & 3 of 3: Repeat for the next angles.
Press the ENTER button to conclude Load Moment
(No Load) calibration.
