The input channels are available as two 16 bit values for further processing. The
measurement result can be calculated by the following formula:
My acquiring the supply voltage accurately together with the bridge voltage in a
transformer, long-term drift and temperature drift are compensated.
If the internal supply voltage (U
supply voltage is required.
