• Do not input TRIG signal when measurement (INDEX signal is OFF) is in progress.
• When settings such as measurement frequency are changed, input the TRIG signal after the
processing time (approx. 15 ms).
• The input signal is disabled when the measurement screen is not open, or when an error
message is displayed.
• The output of the judgment result is determined before the EOM signal becomes ON. When
the response of the controller input circuit is slow, a wait is required from when the EOM signal
ON is detected until the judgment results are read.
