Analyzer
Operational Check
Zero and span within tolerance
limits as described in Subsec.
9.1.3 of Sec. 2.0.9
(Ref. 11).
Level 1 zero and span
every 2 weeks; Level 2
between Level 1 checks
at frequency desired by
user.
Isolate source error, and
repair.
After corrective action,
recalibrate analyzer.
Precision Check
Assess precision as described in
Sec. 2.0.8 (Ref. 11).
Every 2 weeks,
Sec. 2.0.8 (Ref. 11).

AUDIT ACCEPTANCE LIMITS
FREQUENCY AND
METHOD OF
MEASUREMENT
ACTION IF REQUIREMENTS
ARE NOT MET
Multipoint calibration
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)
Re-calibrate the analyzer.
Data processing audit
Adhere to stepwise
procedure for data reduction
(Sec. 8.4); no difference
exceeding
0.02 ppm.
Perform independent
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
Method described in this
section of the Handbook.
At the startup of a new
monitoring system, and
periodically as
appropriate; observation
and checklist.
Initiate improved methods
and/or training programs.
