Notes for Tables 15 and 16:
1.
In the TMX, the offset value (magnitude and polarity) will be subtracted from the data generated by the A/D
converter. The input offset magnitude setting equals the number of 40mV increments.
2.
In the TMR, the offset value (magnitude and polarity) will be added to the data sent to the D/A converter.
The output offset magnitude setting equals the number of 200 μA increm
ents.
