4. Adjust the carrier flow (see Figure 28 and Figure 29) to achieve the CO
2
reading detailed in Table 9.
5. Allowing the reading to stabilize for 10 minutes and fine adjust the reactor
flow for the gas CO
2
ppm reading to the appropriate value in Table 9.
6. Set the flow no lower than 30 cc/min. and no higher than 150 cc/minute
Ensure that the gas concentration remains in this range for a minimum of
5 minutes.
7. Enter the Primary Span calibration, and follow the prompted procedure.
Because the analyzer has already been subjected to the 100% KHP
standard, you may press ENTER repeatedly to skip the elapsing time and
advance to the final screen.
