Command 10: Power Supply Setting
{ 10, Warmup Time (sec) }
Supply starts after receipt of Command 10 when supply time is not zero.
If a sampling Trigger Source is generated before supply time is reached, supply
time takes priority and sampling starts after it is reached. When parameter is –1,
however, sampling starts as soon as sampling Trigger Source is generated.
1–360 Supply time (sec) of 5.3V from Pin 5 to sensor
Decimal part ignored.
0 Corresponds to sensor information supply time.
–1 Corresponds to sensor information supply time.
Sampling Trigger Source takes priority over supply time.
–2 Following receipt of command, power is supplied continuously to the
sensor.
However, the default setting for extended sampling is 100 msec.
• Sampling trigger takes priority over supply time.
• Default is 100 msec. (See “Analog Sampling” on page 3.)
