Note: The number of pulses
are reference only.
This check the photo sensors
which detect the referense angles
for training and tilting operations.
This checks the transducer
training operation. The four digit
figures used to train the
transducer by 180°.
If training is abnormal, NG count
increases by one.
This checks the transducer tilting
operation. If the number of pulses
used to tilt the transducer is
abnormal, NG count increases by one.
This increases by one when
above test has done.
