The impedance accuracy is +/- 0.5% of full-scale impedance. (Full-scale impedance is a function of the load plate current that is used for a particular installation). The voltage accuracy is +/- 0.02 volts from 1 to 15 volts. The current accuracy is dependent on the type of sensor being used. The shunt will give +/- 0.2% of full-scale accuracy and the C.T. will be +/-2% of full-scale accuracy.
