3. The system goes through an initialization period while showing the
firmware version on the bottom line until the LCD displays the
Normal Mode screen.
4. Enable Peak Tracking following the procedure outlined in “To
change parameters in Mode 2” on page 2-15.
5. After initialization and establishment of reference spectra, the LCD
displays four lines, the third of which is blank.
The measurements displayed are:
• ANA: Refers to the concentration in the sample cell (in units) of
the analyte/component selected in Mode 2.
• P: Pressure in the sample cell in units selected in Mode 2.
• T: Temperature in the sample cell in units selected in Mode 2.
6. Continuous updates of the measurement parameters displaying on
the LCD indicates that the analyzer is operating normally.
Powering Down the Analyzer
It may be necessary to power down the analyzer for problem solving or
maintenance reasons. An approved switch or circuit breaker rated for 15 amps
should have been installed and clearly marked as the disconnecting device for
the analyzer.
For systems with heated enclosures, a Temperature too Low or
Temperature too High fault will activate the General Fault
Alarm when the enclosure temperature is more than 5 °C above
or below the specified temperature. Once the enclosure has
reached the specified temperature, reset the General Fault
Alarm (see “To change parameters in Mode 2” on page 2-15).
Definitions for the acronyms displayed on the LCD are given in the
section “Modes Defined” on page 2-5.
