Inconsistent measurements:
1) Brackets incorrectly mounted: are the brackets slipping or loose
or mounted at an angle? (page 4-11). Were the brackets
accidentally knocked during or between measurements?
2) Measurement range too small or too few points: rotate through a
larger angle with more measurement points (page 4-33)
3) Machine preparation problem: excessive bearing play? Check
with Soft foot function (page 4-29). Is the foundation stable? If
suspect, split the coupling and measure with Pass mode (page
4-36). Is the coupling too stiff, e.g. membrane coupling? See
page 6-7.
4) Are the receiver and laser lenses clean? (page 6-36)
Difficulties in alignment:
1) Poor measurement, see reasons listed above.
2) Are corrections being made in the wrong direction? See the rules
on pages 4-34 and 4-50.
3) Check Soft foot (page 4-29)
4) Check machine preparation details (page 4-10). Is the foundation
stable? Are your horizontal moves reasonably accurate with jack
screws or similar?
