Caution
when
replacing chip parts
New
parts
must be attached
after
removal of the chip.
Be
careful not to
heat the minus side of a tantalum capacitor,
because
It
is easily
damaged
by the heat.

A
voltage value
Is
the reference value
between the measurement

is
received
from the color
bar generator,
(digital
