audit
The difference between
the measured and the
audit values as a
measure of accuracy
(Sec. 2.0.8 of Ref. 11).
At least once a quarter
(Sec. 2.0.8 of Ref. 11)

check on a sample of
recorded data, e.g.,
1 day out of every 2
weeks of data, 2 hours
for each day.
Check all remaining data
if one or more audit
checks exceeds
± 0.02 ppm.
Systems audit

section of the Handbook.
At the startup of a new
monitoring system,
and periodically as
appropriate;
observation and
checklist.
Initiate improved
