Replacing the AMPS fuse
The AMPS fuse protects the current input from an over-current condition. Follow the steps
below to replace the AMPS fuse.

carrier one-quarter turn counterclockwise. Release pressure on the jack, and its internal
spring will push the fuse carrier out of the socket.
3. Remove the fuse, and replace it with the same type: 3A, 250V, fast blow, Keithley
part number FU-99-1.
