(5) Measurement start input = CCD trigger, start sampling = parallel, object type change =
parallel, result output = parallel
Note 1: When the settings listed in section 11-3 "CCD trigger" have not been made, a CCD
TRIGGER NOT SET. (error 34) will occur.
Note 2: Start sampling input (X0)
1. Sampling will be performed while this terminal is ON. When it is turned OFF, the
