Timing charts
The following shows the timing charts when communication is performed with external
devices.
■ Measurement
●
Continuous measurement
Measurement is performed continuously for the duration that the TRIG signal is ON.
The measurement result is updated, and output to external devices at each measure-
ment cycle.
● Synchronous measurement
Measurement is performed only once in synchronous with the change in TRIG signal
state from OFF to ON, and the result is output.
• The minimum ON width of the TRIG signal is 1 ms.
• The OUTPUT signal is held until the next measurement result is updated.
Note, however, that when one-shot output is currently set, the OUTPUT signal is held
for the preset time.
