4.0 OPERATION

4.1 Performing CO and Draft Testing

4.1.1 Analyzer Turn On and Warm Up

1. Connect the probe and make sure that the analyzer is properly set

up per Sec tion 3.0.

2. Turn ON the analyzer in fresh air by pressing is I/O button and

observe that the following Warm-Up Screens are displayed.

These screens show the analyzer’s model number, the unit’s soft-

ware revision, and finally the remaining warm-up time. If an O

sensor is installed, then its current output level is also displayed.

Note: The warm-up time is 10 seconds for analyzers that do

not contain an oxygen sensor, and have their CO channel

set up for manual zero. The warm-up time is 60 seconds for

analyzers that contain an oxygen sensor, and/or have their

CO channel set up for auto zero.

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.

3. Wait for the analyzer to count down its warm-up period; after

which, either the CO Screen (Model 100), the CO & Draft Screen

(Model 105), or the Fuel Screen (Model 110/120/125) is displayed.

If, however, any errors were detected during warm-up, the Sensor

Status Screen is displayed. If this occurs, refer to Section 4.13.13 for

information on how to correct the error.
