Adjusting the Calibration
Setting
After the calibration gas flow to the CGA 351 has been established, as
described in the previous sections, the calibration gas setting may be
adjusted as necessary. To adjust the heater setting, complete the
following steps:
1.
Verify that the calibration gas flowing through the analyzer meets
the requirements for oxygen content (5 ppm), flow rate (1,000 ±
150 cc/min) and pressure (1 Atm).
2.
Make sure that the digital display is configured to read the oxygen
concentration in ppm.
Note:
The oxygen sensor calibration is actually accomplished by
adjusting its operating temperature until the required mV
output is achieved.
3.
Adjust the heater setting as follows:
