Normal Start Up Messages

Temperature Locked: WB (HB)
The system waits for the warm box ("WB" – the temperature-controlled
electronics and wavelength monitor chamber) to reach operating temperature.
Similarly, the temperature of the hot box ("HB" – the temperature-controlled
chamber containing the analyzer's optical cavity and gas handling system) is
stabilized. This is typically the longest step in the startup sequence. The duration
of this step can range from 5 to 60 minutes, depending on the ambient
temperature and how much time has elapsed since the last startup.
Entering Measurement
Spectral scanning has started. Concentration measurements will be available in
approximately 30 seconds. The instrument will continue to scan and report
concentration measurements until the instrument is shutdown using the
procedure below.
Pressure Stabilizing/Locked
The valve control system begins to allow flow through the analyzer and stabilizes
the pressure inside the cavity.
Measuring
This is the normal mode of operation after startup has completed.
