3. If necessary, you can adjust the
Offset
parameter to match a reliable reading or instrument
by entering a value in this parameter. (Range: -10.0 to 10.0°F, default = 0.0°F)
4. Repeat Steps 2 and 3 to add offsets to other temperature sensors, as needed.
3.3.2 O2 Sensor
The
O2 Sensor
screen displays the current oxygen (O
2
) reading, and also allows you to enter
an offset, and/or enable Auto Calibration of the O
2
sensor. This sensor is an important part of
AERtrim functionality; the
O2 Sensor
screen is not visible on units
that don’t have an O
2
sensor.

O2 Sensor
.
2. If needed, you can enter an offset value in the
O2 Offset
field to make the reading match
an external meter. The unit must be is operating with sufficient blower speed to measure O
2
.
The current reading appears before and after entry. (Range: -3.0% to 3.0%, default = 1.0%)
3. The
Auto Calibrate Now
feature was designed for units that run continuously and therefore
do
n’t get a chance to calibrate on a defined frequency. To initiate, press
Auto Calibrate
Now
and choose
Yes
. The following occurs:
•
Auto Calibration Status
shows the progress, including the offset implemented.
•
When completed,
Auto Calibrate Now
reverts to
No
.
4. You can define
Calibration Frequency
as
Daily
,
Weekly
,
Monthly
or
Never
.
•
If you choose
Weekly
, the next calibration period will be 7 days from today. For
Monthly
, the first day of the month will be the next calibration period.
•
If you choose
Dailey
, the
Time
(time of day) field appears; choose an appropriate time
to perform the calibration.
