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.
