• Check Gas Pressure specifies the pressure at which the gas within the online line check gas flow cell.
Typically this cell is vented to atmosphere so an atmospheric pressure value (14.7 psiA or 1.01barA) will work.
• Valve Selection specifies which analyzer’s solenoid valve driver is used for the check gas.
• Check Gas Purge Time specifies how long the check gas will purge the check gas flow cell.
• Normal gas Purge Time specifies how long N
2
will purge the check gas flow cell.
• Validation Reading specifies the type of reporting method for the validation concentration (see earlier
explanation of these types).
• Analog Output Mode specifies Block, Track, or Hold of all 4 to 20 mA output during online check.
