C.2 Table Alignment
To check the table alignment (X and Y), the Manual Control Unit (in conjunction
with the
µ Carrier software) is used to manually move the table. Before
performing any check or aligning of the table, the Probot instrument must be
properly leveled.
C.2.1 Leveling
Before checking the alignment or performing any alignment, check to ensure that
the Probot is properly leveled. Use a spirit level if there is any doubt (FIGURE C-
10). If necessary, adjust the four feet until the instrument is leveled properly.

Note: The following procedure discusses all steps using the standard needle. If
the µ-Tee is installed, all steps are identical except step a).
A piece of fused silica is used as ‘test needle’. The table is then moved as close
as possible to the needle tip. The manual control unit is used to control the table
position.
a) Install a piece of fused silica capillary. Adjust ‘X’ to 1 – 2 mm (0.04 – 0.08
