Smart SEM, Stuck at EHT 3 kV Max

Post by user-7065 »

All, a user on our EVO 50 was running the microscope, she was changing the I probe from 28 to 200, then 400 then back to 28 since she didn't see a noticeable difference. The EHT went from the usual 0-30 kV to a 0.2 to 3 kV setting and we can't figure out how to fix it. Has this happened to anyone? Any sage advice? We've updated recently to Windows 10 and the latest version of SmartSEM and just replaced a power supply last week. It was running better than it had in years and now we're stuck at 3 kV max voltage. It's very frustrating, I'm ready to uninstall/reinstall the software, but service told me that would create more problems.
