(2) Sampling processing
Measured temperature value that is measured at every 320ms of sampling period is
stored in the buffer memory.
The Q68TD-G-H02(H01) measures the temperature from CH1 to CH8 every
40ms per channel.
The sampling period indicates the period (320ms) batch-updating the measured
temperature value in one channel in the case of that the sampling processing is
specified with the Averaging processing selection (Un\G24 and Un\G25).
Regardless of the number of conversion-enabled channels, the measured
temperature values are stored in the buffer memory every 320ms.
The conversion speed indicates the maximum time required before the measured
temperature values are stored into the buffer memory.
The following figure shows the timing of storing the measured temperature values
of Q68TD-G-H02 and Q68TD-G-H01 respectively.
