2. The status line will display "Zeroing" (Figure 20) once the calibration gas values have
been sent to the bench, the analyzer will Zero for 30 seconds. then the calibration screen 2
will appear (Figure 21). Once screen 2 appears, calibration gas can be connected and
turned on as indicated on the status line. (Note: Do not adjust the regulator, this was
preset to the appropriate flow rate. DO NOT press the save button with out calibra-
tion gas attached and flowing to the analyzer.)
3. Cal 2 screen shows 3 columns. The first column shows the stored calibration values
typed in from the cal bottle screen 1. The middle column will display the cal gas live read-
ing values from the cal bottle, the last column is a % variance to the calibration values and
the live readings. With the cal gas connected, once the gas values stabilize (Figure 22),
Note: The O2 reading must be 1% or less to activate the save button. press the "Save"
button ( Figure 23). The status bar will show saving cal data, and then calibration complete,
and the values should be reading accurately. A percentage difference value is shown in the
3rd column to see how far off calibration was before and then after calibration (Figure 24).
The calibration process is now complete. Turn the calibration gas off to save gas. The
calibration process should take approx 30-40 sec.
