9.3.3. MANUAL CALIBRATION USING VALVE OPTIONS
The following section describes the basic method for manually calibrating the GFC 7001E/EM Analyzer.
If the analyzer’s reporting range is set for the DUAL or AUTO range modes, a step will appear for selecting
which range is to be calibrated (LOW or HIGH).
Each of these two ranges MUST
be calibrated separately.
9.3.3.1. Setting the Expected Span Gas Concentration
NOTE
When setting expected concentration values, consider impurities in your span gas.
The expected CO span gas concentration should be 80% of the reporting range of the instrument (see Section
6.6.1). The default factory setting is 40 ppm.
To set the span gas concentration, press:
NOTE
For this Initial Calibration it is important to independently verify the PRECISE CO Concentration Value of
the SPAN gas.
If the source of the Span Gas is from a Calibrated Bottle, use the exact concentration value printed on
the bottle.
