Contents: 1) Move all faders up and down over a short
range to perform the learning procedure
for fader drivability (FADER Learn).
2) Move all faders up and down (aging).
3) Drive the faders in a pre-determined
pattern for a pre-determined period of
time, and then measure the distance
a c t u a l l y m ove d t o a u t o m a t i c a l l y

4) Stop all faders at a specified position,
and then detect the positions with the
built-in A/D for automatic determination
purposes (three locations).
Stop the faders at a position where they
are within
±
2mm of the standard fader
position 1, and then visually determine
that there is no extreme misalignment
with fader positions 2 and 3.

1-31 ENCODER (CH) Test
Contents: Check the rotation response of Encoder of
CH1 through CH24.
Rotating the Encoder in clockwise moves
the mark “>” located on the left end to the
right direction. When the mark “>” reaches
the right end, it turns into the mark “<.” After
this, rotating the Encoder counterclockwise
moves the mark “<” to the left direction. If
the mark “<” reaches the left end, it will be
OK.

position is detected with the built-in A/D
(displayed in 1024 resolution)
“NG 02 (840)”
NG 02: The CH2 fader is not acceptable
(NG = No Good).
(840): Actual value when the fader's stop position
is read with the built-in A/D (displayed in
1024 resolution)
The items displayed with “--” in the determination column
represent inspection items for which OK or NG cannot be
determined.
