Machine Troubleshooting
Machine won’t repeat measurement
• Are excessive vibrations occurring in the area of the machine?
• Is the part secure on the table?
• Is the probe tight in Probe Holder? Check that locking knob is tightened.
• Is the probe broken?
• Verify that the trigger force is correct for the stylus length. An incorrectly
adjusted stylus is a source of non-repeatability.
• Shorter stylus lengths will give more repeatable results than longer stylus..
• Review your probing technique.
• Is the diameter of the stylus ball too small? Make sure the stem of the stylus
does not hit against the part being measured.
• Is the temperature of the part, machine and the measuring environment stable
and within specification?
• Is the TP2 (if supplied) screwed tightly into the probe body?
• Is the stylus screwed in tightly?
• Is the probe shanking on the part?
• Is the proper measurement plane selected (XY, YZ, ZX)?
Inaccurate measurements
• Is the part dirty or oily?
• Is the surface finish on the part poor? Using a larger diameter stylus ball will
reduce the effect of surface finish of the part being inspected.
• Was the homing/initialization procedure followed correctly?
• Is an unqualified tip being used?
• Has the tip been moved after qualification?
• Has the qualification sphere been moved since the first tip was qualified? The
reference offsets and tip 1 measurements must be repeated if sphere is moved.
• Has the probe been damaged?
• Check the temperature of the part, machine and the measuring environment.
Are they stable and within specification?
Probe does not take hits
• Are the cables correct and properly connected?
• Is the TTP enabled? See Software Manual for details.
• Is the probe interface (PI-6) loose or not present?
• Has the probe reseated? The red light on the probe should blink off and on each
time a hit is registered. If the light remains off after a hit has been taken, gently
move the stylus or the probe with your finger. The probe light should turn back
on.
• Are the machine and control box cables correct and properly connected?
