Getting Started Teledyne API - Model T200H/T200M Operation Manual
28
The front panel liquid crystal display screen includes touch control. Upon analyzer start-
up, the screen shows a splash screen and other initialization indicators before the main
display appears, similar to Figure 3-2 above (may or may not display a Fault alarm). The
LEDs on the
display screen indicate the Sample, Calibration and Fault states; also on the
screen is the gas concentration field (Conc), which displays real-time readouts for the
primary gas and for the secondary gas if installed. The display screen also shows what
mode the analyzer is currently in, as well as messages and data (Param). Along the
bottom of the screen is a row of touch control buttons; only those that are currently
applicable will have a label. Table 3-1 provides detailed information for each component
of the screen.
