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.
