5.2 Replacing Power Line Fuse
If the instrument display fails to light after switching it on, check the power outlet first. If power is available, and the
instrument fails to operate, the power fuse may be open (blown).
Disconnect the instrument from the power supply before changing the fuse.
Using a screwdriver, turn the fuse holder to the left (counterclockwise) and
remove the fuse.
Check the condition of the fuse. Replace blown fuse by those of the same
type with the same rated value (5 x 20 mm, T6.3H 250 V).
NOTE: If the fuse is good and power is available at the outlet, the cord or
instrument may be defective. Try a new cord. If this does not work, the
instrument should be sent back for servicing.
The use of a fuse of a different type or with a different value as well as
bridging or shunting the fuse is not allowed and can possibly cause a
hazard to your safety and lead to instrument damage!
