5.5 Output Processing

Over large ranges, EC is not linear and is best reported as samples using

instruction P70. In limited ranges, averaging (P71) measurements over time

may be acceptable. Convention requires that the temperature at the time of the

measurement be reported.

;Output processing, convention states that the temperature be reported

;with the EC measurement.
