Replacement Fuse - 3A 250V (Cat. No. 1400-FS5)
If the microscope is plugged in but the illuminator is not turning on, the fuse
could be blown. The instructions below detail how to check for a blown fuse.
You can usually tell a blown fuse by if the wire inside is broken, or the glass is
blackened. Sometimes there will be no visible indication though and it will be
necessary to check the fuse with a conductivity meter or to replace it with a
new fuse.
