The reading on the top surface of the module
should be approximately in the range
1000--2500. If it is too high (>2500), then roughen
the top surface with 400 grit sandpaper. If the
reading is too low ( <1000), then polish the top
surface with fine emery cloth.
If the reading on the fiducial slot is not within
the allowed range (0– 500), gently blow out the
fiducial slot with clean, dry, compressed air.
NOTE: When running the Fiducial Scan
from the Diagnostic Window, repeatability
on subsequent scans should be ±10 counts.
(One count is 1/100 mm.)
If problems with the fiducial scan continue, see
the on-screen Diagnostics Help, which includes
further diagnostics. You need a PIN to enter the
Diagnostics Windows (Tools button) prior to tap-
ping the Help button.
