Ametek 241CE II User Manual page 68

The User Interface is made up of two areas:
•
3-2 | 241CE II Hydrocarbon Dewpoint Analyzer
Display Screen/LEDs
Consists of one self-illuminated line capable of displaying up to 12 alpha-
numeric characters and one row of seven LEDs. The information displayed
depends on the current operation mode.
- The self-illuminated line displays the results of the most recent measure-
ment cycle, mirror temperature, run time, and Status Code (SCode).
To change an operating parameter, it must be active on the display. The
display line flashes when the 241CE II Analyzer is in Standby Mode (a
Fault alarm is present).
- The LEDs provide a visual indicator of the built-in diagnostics function.
When a LED is On, it indicates the alarm condition associated with the
LED currently exists. For more information about this diagnostics tool,
see "Types of Alarms" in Chapter 4.
