between 250 ms and 65,500 ms in 250-ms increments. The default setting for
the sampling cycle is 250 ms.
Note If the sampling cycle is set to a small value, the rate of change will be sensitive
to small changes. If the temperature data is subject to minute fluctuations, and
the sampling cycle is shorter than the cycle of fluctuation, the fluctuation will
be regarded as the rate of change. To prevent this occurring, use moving
average processing, which will set a longer sampling cycle.
