Calibration Gas (Advanced Mode)
You can set the gas that you want as your calibration gas. Calibration
gases are organized in two lists:
• Last Ten is a list of the last ten gases used by your instrument.
The list is built automatically and is only updated if the gas
selected from the Gas Library is not already in the Last Ten. This
ensures that there is no repetition.
