How to setup the measured gas pressure
(8) Enter the pressure (absolute pressure) of the measured gas in "Exhaust gas pressure."
Figure 8.18 Setting Measurement Gas Temperature and Pressure (Humidity Analyzer)
NOTE
• The critical temperature of the saturated water vapor pressure is 374°C. If a gas
temperature exceeding 370°C is entered, no correct calculation will be obtained.
• If an invalid value is set, no correct calculation will be obtained. Be sure to check allowable
temperature ranges of the temperature transmitter you use, and then enter the value
correctly.
