Currently, the enhanced specification double-tilt Be holder for JEM-ARM200F (W Corrector) is malfunctioning.
Repairs completed. (August 23, 2024)

- The specimen stage is tilted and coming off.
- Impression that the rotation axis of Y-tilt is slightly misaligned
- Repair request is currently in progress
- The cause is unknown, but the following possibilities are assumed:
- Parts degraded over time (about 10 years)
- Strong force was applied to the specimen stage when attaching/detaching the specimen
- Pushed strongly with a screwdriver or tweezers
- The holder was inserted/removed while tilted (especially Y-axis).
- The holder interfered with the objective lens.
- The holder was moved while the mechanical limit alarm was occurring (the holder and the objective lens are in contact)
