The functions of the buttons on Cali.Co sub menu are:
• Cali.Len: Sets the optical path length of the calibration tube,
manual.
• Cali.Temp: Sets the temperature of the standard gas used for
calibration, manual or from a measurement. When “Measure” is
chosen, the system enters Measured Temperature Set menu.
• Cali.Pres: Sets the pressure of the standard gas used for
calibration, manual or from a measurement. When “Measure” is
chosen, the system enters Measured Pressure Set menu.
• Cali.Con: Enters the concentration value of the standard gas used
for calibration. This value is used to calculate calibration
coefficients.
• Pre.Cali: After inputting all the parameters above, press Pre.Cali
button to accept them, and the system enters the Calibration
Confirmation menu (Figure 4.27).
Note: The system accepts the above input parameters only after
Pre.Cali is pressed.
