CALIBRATION PROCEDURE
The initial calibration should be carried out using the same reporting range set up as
used during the analyzer’s factory calibration. This will allow you to compare your
calibration results to the factory calibration as listed on the Final Test and Validation
Data Sheet.
The following procedure assumes that the instrument does not have any of the available
valve options installed. Section 5 contains instructions for calibrating instruments with
these options.
If both available DAS parameters for a specific gas type are being reported via the
instrument’s analog outputs e.g. NXCNC1 and NXCNC2, separate calibrations should
be carried out for each parameter.
 Use the LOW button when calibrating for NXCNC1
 Use the HIGH button when calibrating for NXCNC2.
See Sections 4.13.3 and 4.13.4 for more information on analog output reporting ranges.
