3.4.4. INITIAL CALIBRATION
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 3.3.2
for instructions for connecting these gas sources.
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.
If both available DAS parameters for a specific gas type are being reported via the
instruments analog outputs e.g. CONC1 and CONC2 when the DUAL range mode is
activated, separate calibrations should be carried out for each parameter.
 Use the LOW button when calibrating for CONC1 (equivalent to
RANGE1).
 Use the HIGH button when calibrating for CONC2 (equivalent to
RANGE2).
NOTE The following procedure assumes that the instrument does not have any
of the available Valve Options installed. See Section 9.3 for instructions
