7-2 Setting the Measurement Trigger
The measurement trigger can be chosen from the following two types:
• One-shot measurement: One measurement is performed for each external trigger.
• Continuous measurement: Measurements are performed continuously.
Performing One Measurement for Each External Trigger
A measurement trigger is input as the TRIG signal from a proximity sensor, PLC, or other external device.
One measurement is performed when the TRIG signal turns ON.

Timing Chart
1. Turn ON the TRIG signal while the BUSY signal is OFF.
2. Measurement begins and the BUSY signal is turned ON during the measurement process.
3. When the measurement has been finished, the measurement result is output using an OR signal, and the
BUSY signal is turned OFF.
