(7) Measurement start input = CCD trigger, start sampling = parallel, object type change =
parallel, result output = general purpose serial/parallel
When the start sampling input (X0) is turned ON, the CCD trigger is enabled. (Sampling starts)
Note 1: When the settings listed in section "21-3 CCD trigger" have not been made, a "CCD TRIG
NOT SET. (error 34)" will occur.
Note 2: Start sampling input (X0)
1. Sampling will be performed while this input terminal is ON. When it is turned OFF, the
sampling will stop.
During sampling, O will flash in the upper right corner of the operation screen.
2. After the measurement is terminated, sampling will be restarted when the X0
terminal is changed from OFF to ON.
Note: Result output: The data in the block No., set in item "
SET SERIAL BLOCK" on the "OBJ-
TYPE I/O" screen, will be transmitted to the personal computer.
