AC conversions are AC-coupled, true RMS responding, and calibrated to the RMS value of a sine wave input. The basic
accuracy is for sine wave at full scale and non-sine wave below half scale (3 V range only for sine wave measurement).
For non-sine wave accuracy, refer to the following crest factor guide:
1.4 to 2.0, add 0.5% to accuracy
2.0 to 2.5, add 2% to accuracy
2.5 to 3.0, add 4% to accuracy
