4.13 Screen Descriptions

4.13.1 Warm-Up Screens

As soon as the analyzer is turned ON, a series of Warm-Up Screens are dis-

played. These screens show the analyzer’s model number (Pro 100/105/110/

120/125), the unit’s software revision, and finally the remaining warm-up

time counted down from either 10 or 60 seconds. If an O

sensor is installed,

then its current output level is also displayed. The 60 second countdown

only occurs when the analyzer contains an O

sensor, or if the analyzer con-

tains a CO sensor that has been set up for auto zero (refer to Section 3.5.3).

At the end of warm-up, the analyzer’s first display screen appears (refer to

Section 4.12).

Note: If any errors were detected during warm-up, the

Sensor Error Screen (Section 4.13.13) is displayed.

Tip: An O

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.

4.13.2 CO Screen (Model 100)

The CO Screen is displayed after warm-up and shows the current CO level

in ppm. If the probe is being used, insert the probe tip into the area to be

sampled.
