G Checking the Fuses
Measure the resistance value across the fuse. If the measured resistance value is 100 Ω or
greater, it is judged that the fuse has been blown.

SUPPLEMENTARY NOTES
• For the tester, its probe resistance (resistance value at the time of probe shorting) should
be measured before measurement, and compensation should be made with respect to the
measured value of the fuse.
• You cannot accurately determine whether a fuse is blown or not while the associated board
is mounted in the machine. However, if the resistance value measured across the fuse
with the board installed in the machine is 1 Ω or greater, it is highly probable that the fuse
is blown. In such an instance, demount the board and check whether the fuse is actually
blown.
