4.13 Screen Descriptions
4.13.1 Warm-Up Screens Including O
2
Sensor Output
As soon as the analyzer is turned ON, a series of Warm-Up Screens are
displayed. These screens show the analyzer’s model number (Pro E 122 or
Pro E 125), the unit’s software revision, and finally the remaining warm-
up time counted down from 60 seconds, including a measurement of the O
2
sensor’s output level. At the end of warm-up, the Fuel Screen is displayed.
Note: If any errors were detected during warm-up, the
Sensor Error Screen (Section 4.13.11) is displayed.
Tip: An O
2
error will occur when the oxygen sensor’s output
drops to between 80 and 90. Consider replacing the oxygen
sensor when its output level drops below 100.

The Fuel Screen is displayed immediately after warm-up, and is where
an operator chooses which fuel is to be used by the analyzer to calculate
combustion efficiency. Pressing either the  or  button scrolls the dis-
play through the fuel codes. Pressing ENTER selects the displayed fuel
and places the analyzer into its Run Mode. Note that the fuel code will be
displayed in the top right corner of all screens while in the Run Mode.
