CALIBRATION
This section is organized into subsections as follows:
SECTION 4.1 – Important Precalibration Information
: contains important information you should know before calibrating the instrument.
SECTION 4.2 – Calibration Procedures
: describes the procedure for manually checking
calibration and performing actual calibration of the instrument.
SECTION 4.3 – Automatic Zero/Span Cal/Check (Auto Cal)
: describes the procedure
for using the AutoCal feature to check calibration or to calibrate the instrument. (The
AutoCal feature requires that either the zero/span valve option or the internal span gas
generator option be installed and operating).
SECTION 4.4 – Calibration Quality Analysis
: describes how to evaluate quality of each
calibration.
SECTION 4.5 –
EPA Protocol Calibration: provides links to the US EPA website for
references regarding calibration with EPA protocols.
IMPORTANT PRECALIBRATION INFORMATION
Note
A start-up period of 4-5 hours is recommended prior to calibrating
the analyzer.

EQUIREMENTS
The following equipment, supplies, and expendables are required for calibration:
•
Zero-air source
•
Span gas source
•
Gas lines - all gas line materials should be stainless steel or Teflon-type (PTFE or
FEP).
•
High-concentration NO gas transported over long distances may require stainless
steel lines to avoid oxidation of NO due to the possibility of O
2
diffusing into the tubing.
Optional equipment: A recording device such as a strip-chart recorder and/or data logger.
For electronic documentation, the internal data acquisition system (DAS) can be used by
configuring the Datalogger through the Setup>Data Logging menu; Section 2.5.1).
The method for performing an initial calibration for the analyzer differs between the
standard instrument and those with options.
•
See Section 4.2.1 for instructions for initial calibration of the analyzer in its base
configuration.
•
See Section 4.2.2 for information regarding setup and calibration of the analyzer with
Z/S Valve options.
