Accuracies apply for readings between 10% and 100% of full scale. Additional error at crest factor = 3 is typically 1%. Input impedance = 10MOhms nominal. Max. input = 750V rms, 1kV pk. (265V rms on 400mV range). 1kOhm unbalanced CMR = >60dB at DC or 50Hz (60Hz rejection available as factory option).
