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 – Titration Efficiency (TE) Check/Calibration:
describes corrections
made for titration effects.
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.
CALIBRATION REQUIREMENTS
The following equipment, supplies, and expendables are required for calibration:
•
Zero Air Generator (e.g., T701)
•
Span gas source
•
Gas lines - all gas line materials should be stainless steel or Teflon-type (PTFE or
FEP).
•
High-concentration NO
2
gas transported over long distances may require stainless
steel lines to avoid oxidation of NO
2
due to the possibility of O
2
diffusing into the
tubing.
Optional equipment:
Calibrator with photometer option (e.g., T700U) for use with NO and GPT to span the
analyzer.
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).
