• For failure judgment of the rotary
V
Rs
As a guide, amplitude values higher than +4 or lower than -4 may be judged as failure.
The
V
Rs can be set to any position during measurement. Possible symptoms are shown below.
• The volume changes arbitrarily.
• Interrupted sound leakage occurs even if the volume is decreased to the minimum at the Master or ZO
N
E.
• The MIDI signal is output even if the corresponding
V
R is not operated.
• For operation check of a rotary
V
R after replacement
*As an AD value that is displayed on the FL display is the one before a hysteresis removal process,
and as it has an amplitude, an error of about ±2 may be produced.
