Getting Started Model 6200T Total Sulfur Analyzer
Teledyne Analytical Instruments 42
The analyzer’s 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 3-2 provides detailed information for each component of the screen.
ATTENTION COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Do not use hard-surfaced instruments such as pens to touch the control
buttons.
