To change resolution from one value to the other, simply press the <COARSE/FINE> button
on the top of the ROE (coarse is up, fine is down). The movement screen also displays the
resolution in the lower right corner “0.2 (or 0.04)
µ m Res”. Given a resolution in microns, we
can now re-specify the amount of movement per ROE turn in microns for Setups 1 through
4:

Thus, you have a relatively wide range of precision of movement. In practice, many users end
up only using a very non-precise, fast moving setup (#1 or 2, coarse) for quickly positioning
the pipette and then a precise setup (#4, fine) for micromanipulation under the microscope.
You may find that none of these SETUPS delivers the type of responsiveness that you desire
from the MP-285. The
MP-285 Reference Manual
provides complete instructions for defining
and saving your own Setup.
