Preparation for Use
BEFORE REMOVING THE FUSE, THE AC LINE POWER CORD
SHOULD BE DISCONNECTED FROM THE POWER SOURCE
AND THE OTHER END DISCONNECTED FROM THE
INSTRUMENT.
ONLY USE A FUSE OF THE CORRECT RATING AS LISTED IN
"Fuses" on page 2-3. DO NOT use repaired fuses or short-circuited
fuseholders: For continued protection against fire, replace the line fuse(s)
only with fuse(s) of the same voltage and current rating and type.
The fuse is removed by inserting a suitable flat bladed tool into the slot
in the fuse cap and turning counter-clockwise. The cap and the fuse can
then be removed and the fuse changed for another of the correct rating.
The fuse rating and HP part number are listed in "Fuses" on page 2-3.
