3-3 REESTABLISHING PROPER CALIBRATION CHECK GAS FLOW RATE

The calibration check gas flow must be enough to ensure no combustion flue gases mix with the calibration check gases and only clean, good calibration check gas surrounds the cell without expending excess gas (Figure 3-3). Monitor the O2 concentration using an IRC or HART Com- municator. Set the calibration check gas flow rate as follows:

NOTE

Only set the calibration check gas flow rate at startup. It is not necessary to perform this procedure for each cali- bration check.

a.Adjust the calibration check gas flow to 5 scfh (2.5 L/min.) to ensure the cell is sur- rounded by calibration check gas. Due to the cooling effect of the gas, the cell tem- perature will decrease slightly, causing the O2 concentration to drop. Once the elec- tronics compensates for this effect, the O2 concentration will stabilize.

b.Next, slowly reduce the calibration check gas flow until the O2 concentration changes, which indicates that the calibration check and flue gases are mixing. Increase the flow rate until this effect is eliminated.
