Note:
Maximum output from the calibrator's terminals is 2.2 A. Uncertainty specifications for 220 mA and 2.2 mA ranges are increased
by a factor of 1.3 when supplied through 5725A terminals.
Specifications are otherwise identical for all output locations.

±200 x I
ppm for >100 mA on 220 mA range
2
±10 x I
ppm for >1 A on 2.2 A range
For fields strengths >0.4 V/m but ≤3 V/m, add 1 % of range.
