Notes:

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.

1.Stability specifications are included in the Absolute Uncertainty values for the primary specifications.

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 0.5 V.

0.1x actual load

4.For higher loads, multiply uncertainty specification by: 1+

maximum load for full accuracy

5.The calibrator’s compliance limit is 2 V for outputs from 1 A to 2.2 A. 5725A Amplifier may be used in range- lock mode down to 0 A.

Minimum output: 0 for all ranges, including 5725A.

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