SONOPLOT MICROPLOTTER Proto, Manual

Page: 26 / 67

The sizes of the large and small steps are set by the Large Step and Small Step text input
boxes. All values are in microns and can be set differently for each axis. Set the large step to
10000 microns (one centimeter), to move one centimeter at a time, and grossly position the
robot above the upper-left corner of the microscope slide.
Warning : Avoid bringing the dispenser close to the surface using this step size, as over-
shooting the surface too far will damage the glass needle.
Change the large step size to 1000 microns (one millimeter) and more finely position the
dispenser relative to the surface of the microscope slide. Click on the
Find surface
button
above the manual controls to have the dispenser move down slowly and detect the height of the
surface. If this stops before the dispenser is visibly contacting the surface, or overshoots and
needs to be cancelled manually (using the abort button in the center of the manual controls),
consult Chapter 6, Troubleshooting. Once on the surface, move the dispenser up by 500
microns.
