Default Vacuum Initiation problem for JEOL 6460LV
Hey guys,
we recently moved a JEOL 6460LV from its original location to a new facility. The enitre system is working normally except for its ability to maintain high vacuum or low vacuum. Have any of you experienced a similar problem regardless of the type of SEM you have ? Can you guys think of any possible solutions. My best guess right now is either the pressure sensors have gone bad or that there is insufficient oil in the rotary pumps.

Any help would be greatly appreciated.

Thanks
Prawi

hi,
i think something wrong with pump, this can be the reason about low vacuum.
