TARE Function
The TARE function calculates the net weight of the load
(Total Load –Hook Block). The TARE function must be
activated before lifting. To use the TARE function:
• Rig the load to the hook block.
• Before lifting the load, press the TARE function.
• Lift the Load. The net load is shown in the actual number
display.
The TARE button icon will flash blue in color when active.
Changing the boom angle or length automatically returns the
actual load display back to the total weight (Load +Hook
Block).
