Dear Valued Customer,

Basic Accuracy is measured at the full scale range point. For the CR4411, the reading at full scale and 60 Hz would be 10 VDC +/- 0.5% or +/- 50 mVDC. Absolute accuracy at this point is equal to the basic accuracy.

For this same part at half full scale input, the output would be 5 VDC +/- 50 mVDC, or +/- 1% absolute accuracy.

This is typical of transducers, where they give the most accurate reading at full scale operation.
