How to Correct the Problem
Same as IN1FL above.
1. Check the configuration for each item and
reconfigure if necessary.
1. Make sure the input signal is correct.
2. Make sure the Ratio and Bias settings are
correct.
3. Recheck the calibration. Use Bias of 0.0
1. Make sure the input signal is correct.
2. Make sure the Ratio2 and Bias2 settings are
correct.
3. Recheck the calibration. Use a Ratio2 of 1.0
and a Bias2 of 0.0.
