Alignment Misalignment Perform System Alignment or Sample Alignment
procedures described in this manual. The cross
hair becomes stable only if there is signal. If
there is no light hitting the detector, the cross
hair will be jumpy. Therefore, when performing
the alignment, the first step is to make sure
there is light hitting one or more of the four
quadrants by looking at the intensity (grey area)
on the screen. Ignore the cross hair position
until all 4 quadrants receive some amount of
the light.
No white light Check lamp and light problems chart.
One or more
motors do not
turn. Loose connection Check all cable connections.
Blown fuse
Check fuses on the EC.
Bad Motor Driver
in EC Check/Replace Driver. This can be verified by
looking at the drivers to see if there are red
LEDs next to drivers. If so, the driver may be
defective.
Alignment not
sensitive to the
sample tilt. The sample is not
properly aligned Re-align the sample, ensuring that the beam is
centered on the aperture of the receiver unit.
Use of optional Focusing attachment reduces
sensitivity to sample tilt.
