Turn on the analyzer
Turn on the main AC power to the analyzer.
After a purge, the pumps and UV lamps turn on and the IR detector increases to operating
temperature. The analyzer goes online when the IR detector is at operating temperature (50 °C).
After a loss of power or a software reboot, the analyzer turns on and a purge is done before the
analyzer goes online. To skip the purge, push ENTER.
Start-up checks

intended application.
2. Make sure that the sample inlet line(s) is in the zero standard container.
