To establish a new zero, press “1”. In the unlikely event that the instrument is
experiencing problems, the display indicates “Please wait...” and/or “Please wait while
system warms up...”. To view the details on the Warm Up Status screen, Press “1”. In
the example screen, both the chopper is not locked at the proper frequency and the filter
is not properly positioned. In cases like this, contact the factory for assistance.

Warm Up Status Screen
If the analyzer mode is not zero, or scan, and pressure compensation is configured ON,
the display shows the previously entered pressure and allows accepting or changing it
(see Chapter 7, “Pressure Compensation”, for configuration). If a new pressure is
entered, the display responds “ACCEPTED” or presents an “!INVALID VALUE!”
message.
Note
: SapphIRe does not measure pressure. This must be determined from an external
source, and entered by the user at the beginning of each analysis.
Next, the analyzer checks its pathlength. The analyzer is set to one of two pathlengths;
short (0.5 m) or long (12.5 m). If the pathlength is not correct for the application, the
display prompts to change the pathlength. See “Changing the Pathlength”, in this
chapter.
The instrument then displays the Install Chemical Filter screen, shown below. When the
chemical (zero gas) filter is connected to the IN port, press ENTER.
