Calibration Menu screen displays.
Step 2. Raise the drive unit to its home position.

This value is automatically set when a vessel temperature start
is performed. See “Vessel Temp Start” on page 83.
Note
Ensure the basket assemblies are installed and the standard
evaporation covers are removed prior to beginning this
