5.3. MANUAL CALIBRATION
The following section describes the basic method for manually calibrating the Model
T200H/M NO
X
analyzer.
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
