If both available DAS parameters for a specific gas type are being reported via the
instruments 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 Section 4.13.4 for more information on analog output reporting ranges
