Notes:
Maximum output from 5700A terminals is 2.2A. Uncertainty specifications for 220
µ
A and 2.2 mA ranges are increased by 1.3 x plus 2
µ
A when
supplied through 5725A terminals. Specifications are otherwise identical for all output locations.
1. Temperature coefficient is an adder to uncertainty specifications that does not apply unless operating more than
±
5°C from calibration temperature.
2. For larger resistive loads multiply uncertainty specifications by:
(
actual load
maximum load for full acuracy
)
2
3. 1.5V compliance limit above 1A. 5725A Amplifier may be used in range-lock mode down to 1A.
4. For resistive loads within rated compliance voltage limits.
Minimum output:: 9
µ
A for 220
µ
A range, 10% on all other ranges. 1A minimum for 5725A.
Inductive load limits: 400
µ
H (5700A or 5725A). 20
µ
H for 5700A output >1A.
Power factors: 5700A, 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, 1.200k-10.000k
Uncertainty:
±
0.01%
Resolution: 11,999 counts
Settling time to full accuracy: 5 seconds for 5700A ranges; 6 seconds for 5725A 11A range; +1 second for amplitude or frequency range change.
Overshoot: <10%
