Flowchart for acquiring a judgment result or a measured value with
the external trigger setting
The owchart indicates the procedure with the external trigger setting from the start of the measurement to
the acquisition of a judgment result or a measured value. The instrument outputs the EOM signal immediately
after the judgment results (HI, IN, LO, PASS, FAIL, ERR) have been determined. If the response of the
controller’s input circuit is relatively slow, a waiting time is necessary from between the detection of the EOM
signal switching to on and the acquisition of the judgment results.
