Note:
Maximum output from the calibrator’s terminals is 2.2 A. Uncertainty specifications for 220 A and 2.2 mA ranges are increased by a
factor of 1.3 plus 2 µA when supplied through 5725A terminals. Specifications are otherwise identical for all output locations.
1. For fields strengths >0.4 V/m but ≤3 V/m, add 1 % of range.
