Since Bad Sensor Values (BSVs) are NOT processed
313
, they are NOT
entered into the circular buffer. Hence, many BSVs can cause the Data
Invalid Flag to be set to 1.
Data Output #8, the Running Total (T
running
), is the sum total of all the values contained within the
circular buffer.
Data Output #9, the Array Size (A
size
), is the number of values that the circular buffer can contain.
Data Output #10, the Array Index, is the current value being pointed to in the circular array that was
updated.

E1 Process Error Code
Assumptions: None.
This process reads, sums, and averages input data referenced by Line Item #4. Unlike the Averaging
Process that stores a single accumulative sum across the Sample Interval, the Block Averaging Process
divides the Sample Duration
314
into blocks of time as specified by Line Items #5 and #6.
To work properly, the product of Line Items #5 and #6 must be less than or
equal to the Sample Duration Time
315
.
