Operation PEM-9004
Teledyne Analytical Instruments 44
CO concentration is below a factory preset threshold the value of which
depends on the sensor installed.
Whenever the CO pump is on (whether it is started automatically or
manually) a scored out CO-symbol appears in the status line as shown in
the screen display below.
.
If the CO-flushing-pump starts automatically due to an excess
concentration of CO it cannot be switched off manually until the CO-
concentration falls below a factory preset value.
Once the CO-concentration has reached the lower range the CO-
flushing-pump will automatically shut off.
If the analyzer is equipped with two CO-sensors the result of the
higher range sensor will be displayed when the lower range sensor is
flushed.
The active CO-flushing-pump has no influence on any other
sensors within the analyzer.

The measured data can be printed out by means of a wireless
