3. Confirm settings for the specified probe being used.
4. Allow nitrogen (N
2
) Cal 0 gas to flow through the system for 45 to
60 minutes to purge the system. Refer to Table 4–5.
In the upper section of the main screen, the Present Values measured by the
OXY5500 are displayed. Refer to Figure 4–45.
Settings specified in the calibration certificate must be used for
probes. Refer to the calibration certificate example in Figure 4–34
on page 4–32 and the analyzer screen shown in Figure 4–31 on
page 4–30.
