Following the on screen directions, enter in the pressure of the
gas within the on-line 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.
Press ENT to proceed.
Enter in the temperature of the gas within the on-line line check
gas flow cell. Typically this cell is the same temperature as am-
bient. Use a thermometer, DVM with appropriate thermocouple
attachment or radio to the control room for an ambient reading.
