I am using refernece board RD9z1_638_4Li based on MM9z1_i638 controller. I am finding it difficult to understand the channel acquition system. I have few questions about it hope they will be answered here:
1. How do i calibrate the voltage and current channels?
2. What is the effect of using digital chopper in voltage and current channel?
3. Effect of iir filter on V and I reading?
4. Effect of Low pass filter on V and I reading?
I am using demo code that comes with the reference board. Board is running fine. I am getting voltage reading with error in mV .
