Normal:
An already-known value appears.
(In this example, the commercial
voltage level should appear.)
Abnormal:
The measured value does not
appear.
The malfunction may occur.
Stop the inspection and do not use
the instrument.

Check that the fuse is not broken.
Check method Action
1. Remove the fuse from the
instrument. (p. 106)
2. Reattach the battery cover.
3. In the resistance measurement,
check the resistance of the
fuse. (Resistance measurement
(p. 44))

Abnormal:
If the value above is not obtained (the
value higher than that is displayed),
replace the fuse. (p. 106)
