Notes:
Maximum output from 5720A 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 A when supplied through 5725A terminals. Specifications are otherwise identical for all output locations.
1. Stability specifications are included in the Absolute Uncertainty values for the primary specifications.
2. Temperature coefficient is an adder to uncertainty specifications that does not apply unless operating more than 5 °C from
calibration temperature.
3. For larger resistive loads multiply uncertainty specifications by:
4. 1.5 V compliance limit above 1 A. 5725A Amplifier may be used in range-lock mode down to 1 A.
5. For resistive loads within rated compliance voltage limits.
6. For outputs from the Aux Current terminals, the maximum resistive load for full accuracy is 1 k
multiply the uncertainty as described in Note 3.
Minimum output: 9 A for 220 A range, 10 % on all other ranges. 1 A minimum for 5725A.
Inductive load limits: 400 H (5700A/5720A, or 5725A). 20 H for 5700A/5720A output >1 A.
Power factors: 5700A/5720A, 0.9 to 1; 5725A, 0.1 to 1. Subject to compliance voltage limits.
Frequency:
Range (Hz): 10.000-11.999, 12.00-119.99, 120.0-1199.9, 1.200 k-10.000 k
Uncertainty: 0.01 %
Resolution: 11,999 counts
Settling time to full accuracy: 5 seconds for 5700A/5720A ranges; 6 seconds for 5725A 11 A range; +1 second for amplitude
or frequency range change.
Overshoot: <10 %
