Notes:

Maximum output from 5700A terminals is 2.2A. Uncertainty specifications for 220 μA and 2.2 mA ranges are increased by 1.3 X when supplied through 5725A terminals.

Specifications are otherwise identical for all output locations.

±200 X I2 ppm for >100 mA on 220 mA range

±10 X I2 ppm for >1A on 2.2A range

2.Temperature coefficient is an adder to uncertainty specifications. It does not apply unless operating more than ±5°C from calibration temperature.

3.Burden voltage adder is an adder to uncertainty specifications that does not apply unless burden voltage is greater than 0.5V.

5. 5700A compliance limit is 2V for outputs from 1A to 2.2A. 5725A Amplifier may be used in range-lock mode down to 0A. Minimum output: 0 for all ranges, including 5725A.

Settling time to full accuracy: 1 second for μA and mA ranges; 3 seconds for 2.2A range; 6 seconds for 11A range; + 1 second for range or polarity change
