G-5
10. The formula to corect the slope of the
line or the current calibration is simple.
Displayed weight change x
Actual weigh change
During the record keeping you find that when
you fill the vessel with 50,000 lbs of material,
the actual weight change is 47,600 lbs.
47,600 lbs/50,000lbs
*current scf_cnt = corrected scf_cnt
47,600/50,000 = .952
.952 * current scf_cnt = corrected scf_ent
This procedure will change the slope of the
line. As seen in figure G-1, the zero point will
change because of this. A new zero point will
be needed. If the amount of material in he
vessel is know, a zero-cal can be done.
Refer to page 6-6 for instructions on this
procedure.
