Dear all,
We bought a X'PERT PRO 14 years ago with all the optics possibilities at
that time (Bartels, Hybrids, Texture, Solllers of all kinds, Rocking
curve attachments, mirror ...). For few years, we got at random
positionning errors. During scans, the motors never reach a software
understandable value (or never even go to it). This started originally
on the Z-micrometer control, and shifted to omega more recently.
Rebooting the whole stuff is actually not everytime enough to
reinitialise the instrument. After some maintainance days, the proposed
solution from Panalytical is to replace the omega circle.
I would like to get your feeback on this, whether you got similar
problems and given solutions, if it helps or not afterwards.
I did not look at the original contract to see if Panalytical is indeed
informing that goniometer circles are running correctly for a restricted
lifetime, or if circle replacements should be operated on a say 10-years
base ...
sincerely
daniel
