2. Turn ON the analyzer by pressing its I/O button and observe that a
series of three Warm-Up Screens are displayed.
The first screen identifies the model number of the analyzer, the
next screen shows the software revision number, while the last
screen counts down the warm-up time from either 10 or 60 seconds.
If an oxygen sensor is installed, its 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.

1. Turn ON the analyzer and allow it to warm-up.
Important: If the CO channel is set up for auto zero, then
the analyzer must be turned ON in fresh air; otherwise,
incorrect CO readings will occur. If the CO channel is set
up for manual zero, and if the CO reading is higher than
zero when sampling fresh air, then the CO channel must be
manually zeroed per Section “CO Channel Zero” on Page 13.
