Note 9: If the DC offset detection mode is ON, the information which the DC offset is appeared is added.
For example,
a) ch1+ is connected to GND
b) ch1− is connected to V
c) They can read or get the “Short to GND” information when the uP send the Read command.
d) Next, however, they can not get the “Short to GND” or “Short to V
