Continuous Measurements
Example: Only Data 0 Set for Parallel Data Output
Timing Chart
1
The RUN signal turns ON when measurements are enabled and the Sensor is in Run Mode.
2
Turn ON IN7 while IN0 to IN6 are OFF. If this status is held while the BUSY signal is OFF, contin-
uous measurements will begin and the BUSY signal will remain ON while continuous measure-
ments are being performed.
3
When measurement results are output, the GATE signal is turned ON when the time that is set in
the [GATE ON delay] parameter in the communications settings has elapsed.
*1
4
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.
*1
*1 Set the GATE ON delay and output time for the GATE signal so that the total time does not exceed the output period.
5
Continuous measurements end when the IN7 signal is turned OFF.
The ERROR signal will turn ON if the input command is not executed normally.
Set at least one data output for parallel judgement output and then read the OR signal when the GATE signal turns
ON.
