Delta measurement process

The Delta process is shown in
conversions are performed to yield a single Delta reading. When Delta starts, three Model
2182/2182A A/Ds (A, B, and C) are performed and the Delta reading is calculated. After
the 1st Delta cycle, the moving-average technique is then used. As shown, a Delta reading
is yielded for every subsequent Model 2182/2182A A/D. The new A/D replaces the oldest
A/D in the Delta calculation.
