Subject Item Method Criterion
Check whether there are stains
and dust attached.
Visual inspection
No exception
occurs.
Note:
Discoloration of
copper bars
does not mean
that they cannot
work properly.
Conductor
and wire
Check whether the conductors are
deformed or their color change
due to overheat.

Determine the
service life
based on the
maintenance
information, or
measure them
through
electrostatic
capacity.
No exception
occurs.
Check whether the electrostatic
capacity is measured as required.
Use instruments
to measure the
capacity.
Electrostatic
capacity

Resistor
Check whether there is
displacement caused due to
overheat.
Olfactory and
visual inspection
No exception
occurs.
Check whether the resistors are
disconnected.
