PROC

This value is the calculated process value
shown as an integer. The decimal point and
exponent values are required to determine the
actual scaled value.
Range = -999 to 9999.
For example: If the process = oxygen, display
decimal point = 2, and exponent = 6, and
PROC = 1234, then the actual value and
displayed as 12.34 ppm.
