• Check Gas Pressure species the pressure at which the gas within the online line check gas ow cell.
Typically this cell is vented to atmosphere so an atmospheric pressure value (14.7 psiA or 1.01barA) will work.
• Valve Selection species which analyzer’s solenoid valve driver is used for the check gas.
• Check Gas Purge Time species how long the check gas will purge the check gas ow cell.
