AC + DCV Accuracy (ACDCV Function)
For ACDCV Accuracy apply the following additional error to the ACV accuracy. (% of Range).
Additional Errors
Apply the following additional errors as appropriate to your particular measurement setup. (% of Reading)

Settling Characteristics
For first reading or range change error using default
delays, add 0.01% of input step additional error.
