3.3. Initial Calibration Procedure

The next task is to calibrate the analyzer.
To perform the following calibration you must have sources for Zero Air and Span
Gas available for input into the sample port on the back of the analyzer.
Span Gas is a gas specifically mixed to match the chemical composition of the type
of gas being measured at near full scale of the desired measurement range.
In the case of CO measurements made with the TAPI Model 300E Gas Filter
Correlation Carbon Monoxide Analyzer it is recommended that you use a gas
calibrated to have a CO content equaling 80% of the range of compositions being
measured.
EXAMPLE: If the application is to measure between 0 ppm and 50 ppm, an
appropriate Span Gas would be 40 ppm. If the application is to measure between
0 ppm and 100 ppm, an appropriate Span Gas would be 80 ppm.
Span Gas can be purchased in pressurized canisters or created using a Dynamic
Dilution Calibrator such as the T-TAPI Model 700.
Zero Air is similar in chemical composition to the earths atmosphere but scrubbed
of all components that might affect the analyzers readings.
In the case of CO measurements this means CO, CO
can be purchased in pressurized canisters or created using a Zero Air Generator
such as the TAPI Model 701.
While it is possible to perform this procedure with any range setting we recommend
that you perform this initial checkout using the 50 ppm range.

If you are using the M300E for EPA monitoring, only the calibration
method described in Section 8 should be used.
The following procedure assumes that the instrument DOES NOT have any of
the available Zero/Span Valve Options installed.
See Section 5.2 for information regarding setting up of Z/S Valve options.
See Section 7 for instructions for calibrating instruments possessing Z/S Valve
Options.
