3.8. 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. See Section 3.1.3 for instructions for connecting these
gas sources.
While it is possible to perform this procedure with any range setting we recommend that you perform this
initial checkout using the 500 ppm range.
NOTE
The following procedure assumes that the instrument does not have any of the available
Zero/Span Valve Options installed.
See Section 7.4 for instructions for calibrating instruments possessing Z/S valve options.
