2. The system goes through an initialization period, then the LCD
displays the Normal Mode screen.
3. Three to four minutes are required for the analyzer to establish
reference spectra before displaying a reading.
4. After establishing the reference spectra, the LCD displays four lines,
the third of which is blank, as shown in Figure 3–1. Continuous
updates of the measurement parameters displaying on the LCD
indicate 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. If the optional heated enclosure was ordered, an approved switch
or circuit-breaker rated for 15 amps should have also been installed and clearly
marked as the disconnecting device for the heater.
To Power Down the Analyzer:
1. Switch off the power to the analyzer (and heater, if applicable) using
the switch(es) or circuit-breaker(s) designated as the disconnection
device(s) for the equipment.
2. If the analyzer is going to be shut down for some time, turn off the
sample gas line shut-off valve. It is recommended to disconnect the
power completely to prevent potential damage from lightning
strikes.
