Inserting the fuse holder without first placing a replacement fuse into it may make it difficult
to remove the fuse holder. Be sure to load a replacement fuse before inserting the holder.
12.2 Replacing the Measurement Circuit’s
Protective Fuse
• Replace the fuse only with one of the specified type, characteristics,
rated current, and rated voltage.
Do not use fuses other than those specified (especially, do not use a
fuse with higher-rated current) or do not short circuit and use the fuse
holder. Doing so may damage the instrument and result in personal
injury.
Fuse type: F500mAH/250V (non-arcing) 20 mm × 5 mm dia.
• To avoid electric shock, turn off the main power switch and discon-
nect the cords and leads before replacing the fuse.
