Regarding operation of the output offset detection, The software always detects the output offset
but the result is not latched internally as shown in the Figure below:
However, this detection has to be performed in real time: Time voltage offset (Tvos) between read
and next read is set at Tvos
= 1/the lowest signal frequency ,or more. For instance Tvos > 50 ms if the
lowest output signal frequency is 20 Hz, and to obtain 2 or more readings in order not to make a
misjudgment
Additionaly, the threshold level is designed at
+/2 V.
