MicroTouch Autofocuser Operating Instructions Manual page 8

You can reset the current position to any value between 0 and 60000 by entering that
value in the Target Position box and pressing Reset to Target Position.
Common positions that you use can be stored in the Favorite Locations boxes. For
example, if you know your telescope focuses at about 12000 steps with an eyepiece and
about 41000 counts with a camera, you can quickly go between those positions.
Temperature Tab
The Temperature tab is where you can view the current temperature reading from the
temperature sensor on the MicroTouch unit, and where you can train and enable
temperature compensation.
To train temperature compensation, first focus the telescope, then check the box next to
Learn. This will snapshot the current position and temperature. You should then wait
some time while the temperature drops by several degrees. During this period you can
otherwise use the MicroTouch as normal. Once the temperature has dropped by a few
degrees, refocus the telescope and uncheck Learn. This will take a second snapshot of
the current position and temperature and determine a Coefficient in counts per degree.
