6. Once balanced, replace the sensor cap and make sure the balance
indicator does not change.
7. On the OptiSonde analyzer, enter the Function Control screen to
reach AUTO.
If the "Automatic Balance" is set for "Pacer," the system will first
cool, then heat. If the unit is set for "Auto," it will only heat. The
system will then automatically fine tune the optical balance. The
word Balance will appear in the lower left of the display,
followed by the phrase Acquiring.
The unit will then cool to the dew point and the balance indicator will
increase when dew or frost condenses on the mirror. The dew point
reading might overshoot, then it will stabilize (assuming the sensor is
exposed to constant humidity).
When a stable dew or frost layer is attained, you will see the word
Control in the lower left. The OptiSonde is now reading the correct
dew/frost point and a stable dew or frost layer has been established.
When the OptiSonde is exposed to typical room humidity, this
process takes 5-6 minutes. For very dry conditions, the unit may not
display Control for several hours; however, the PACER indicator will
go out. The sensor must first accumulate a dew or frost layer on the
mirror before it can display Control.
During large changes in moisture, the
to Tracking. This is normal, and indicates that the OptiSonde is
tracking the moisture level. When the moisture level stabilizes, the
control indicator will reappear.

steps 1-7.
