Multiple Graduation Break Points
The PT300 has the ability to have multiple graduation values set. Following is an example
of setting graduation break points. Example:
Grad = Initial graduation equals by 0.1 lb
Cap = 10000 (Capacity equals 10,000 lb)
bP 1
bP 1 bP 1 bP 1 = 1000
bP 2
bP 2 bP 2 bP 2 = 2000
bP 3
bP 3 bP 3 bP 3 = 5000
