28.3.2 CURRENT MEASUREMENTACCURACY
ThechartsbelowshowguaranteedmaximumcurrenterrorsforDC,MAINS,AVIONICS,and50kHzthroughouta100µAto30Arange
ofappliedcurrentsexpressedas%ofreadingandarevalidwithin±5Cofthecalibrationtemperature(add0.005%perCbeyond
this)andwherenosignificantcommon‐modeispresent.Followingthechartsisatablewhichcanbeusedtocalculatethe
guaranteedaccuraciesforapplicationsotherthanshowninthechartsandalsoforthecomputationofnumericalerrors.
