<6. BASIC OPERATION>
BASIC CONfIGURE
PATH LENGTH – allows adjustment of the optical path
(distance the laser is exposed to the process gas).
PRESSURE – allows adjustment of the gas pressure value if
using fixed pressure. If the analyzer is using active pressure
compensation (live signal fed from pressure transducer) no
changes are allowed. Active pressure compensation settings
are found in Advanced Menu.
TEMPERATURE – allows adjustment of the gas pressure value
if using fixed pressure. If the analyzer is using active pressure
compensation (live signal fed from pressure transducer) or
active ambient, no changes are allowed. Active pressure
compensation settings are found in Advanced Menu.
IP ADDRESS – displays the analyzer IP address
SERIAL NO. – displays analyzer serial number
VERSION – software version number
The spectra screen (raw detect, left or absorption, below)
allows capture and view of current spectra.
The screen auto scales the vertical (Y) axis; this will result in a
visually noisy spectra when at low gas levels.
In fact the spectra may not be noisy, but simply that the display
range is extremely low.
