*1: You can change the settings of when the GATE signal is turned ON after the measurement data is output and the length of time that the
GATE signal will remain ON.
Setting the Output Timing for the GATE Signal: p. 66
Note
The GATE signal will not be output if there is no data set for parallel judgement output and parallel data output.
If only the OR signal is output, read the OR signal when the BUSY signal turns OFF.

The RUN signal turns ON when measurements are enabled and the Sensor is in Run Mode.
2
Turn ON the TRIG signal while the BUSY signal is OFF.
3
Measurement begins and the BUSY signal is turned ON during the measurement process.
4
When the measurement has been finished, the measurement results are output using an OR sig-
nal and the D0 to D15 signals, and the BUSY signal is turned OFF.
*1 You can also set the [BUSY output] parameter so that the BUSY signal is turned OFF after the completion of data logging, image logging,
or displaying results.
5
After the BUSY signal turns OFF, the GATE signal is turned ON when the time that is set in the
[GATE ON delay] parameter in the communications settings has elapsed.
6
The GATE signal is turned ON, and then the GATE signal is turned OFF when the time that is set
in the [Output time] parameter in the communications settings has elapsed.
*2 Set the GATE ON delay and output time for the GATE signal so that the total time does not exceed the output period.
