(1) Accuracy is specificed at terminals of Powermoniter II. User supplied transformers may affect accuracy.
(2) For detailed performance curves, refer to Publication 1403-2.2, Powermoniter II Specification Sheet.
(3) Actual full scale is determined by multiplying by user transformer ratio.
(4) The low end of frequency range is 40 Hz for the 1403-LM and 1403-MM in filter mode 1.
(5) Product Cat. No. identifies unit as a 1A or a 5A device.
