Making of Self-made Tool
● To inspect and adjust the output waveform of MR encoder, it is necessary to make a self-made tool by using
the main PCB (IS020-426) of
replacements/repairs, use the defective one.)
Make a self-made tool according to the following procedure.
Use this range.

③ Solder the three wires on the pattern of
the front-side PCB.

① Remove the mounted parts/elements (condenser,
transistor, IC, etc.) from the both faces of the
PCB within the range of the dotted lines. (See
the left.) Do not remove the connector.
(The parts/elements are not always needed to
be removed, if they are not affected by the next
cutoff or soldering.)
② Cut off the PCB along the dotted lines.
④ Solder the one wire on the pattern of the
back-side PCB.
