Calibration Frequency - Teledyne 300E Instruction Manual

EPA Protocol Calibration
8.1.6.2. Data Reduction Audit
A data reduction audit involves transcribing analyzer data and determining if the
collected data is within the control limits, generally ±2 ppm between the analyzer
response and the audit value. The resulting values are recorded on the SAROAD
form. If data exceeds ± 2 ppm, check all of the remaining data in the 2 week
period.
8.1.6.3. System Audit/Validation
A system audit is an on-site inspection and review of the quality assurance
activities used for the total measurement system (sample collection, sample
analysis, data processing, etc.); it is an appraisal of system quality.
Conduct a system audit at the startup of a new monitoring system and periodically
(as appropriate) as significant changes in system operations occur.

8.1.7. Calibration Frequency

To ensure accurate measurements of the ambient CO concentrations, calibrate the
M300E at the time of installation, and recalibrate it:
1. No later than 3 months after the most recent calibration or performance audit
which indicated the M300E response to be acceptable; or
2. Following any one of the activities listed below:
An interruption of more than a few days of operation.
q
Any repairs which might affect its calibration.
q
Physical relocation of the Analyzer.
q
Any other indication (including excessive zero or span drift) of possible
q
significant inaccuracy of the unit.
Following any of the activities listed in above, perform Level 1 zero and span checks
to determine if a calibration is necessary. If the zero and span drifts do not exceed
the calibration limits in Section 12 Q.A. Manual
a calibration need not be performed.
