Replacing Fuses
6.4 Replacing Fuses
If a fuse is blown, replace it with a new one as follows.
For details on how to check that the fuse is blown, see “3 Check
that the fuse is not broken.” (p. 35).
WARNING
Replace the fuse only with one of the specied type,
characteristics, rated current, and rated voltage.
Do not use fuses other than those specied (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.

The fuses can be purchased via authorized Hioki distributors or
resellers.
When removing the fuse, do not apply excessive force on the fuse
holder. If the fuse holder is deformed, the connection becomes
poor and the instrument cannot measure the current.
