Notes:
Maximum output from the calibrator’s terminals is 2.2 A. Accuracy 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 Accuracy values for the primary specifications.
2. Temperature coefficient is an adder to Accuracy specifications. It does not apply unless operating more than
±
5
°
C from
calibration temperature.
3. Burden voltage adder is an adder to Accuracy specifications that does not apply unless burden voltage is greater than 0.5 V.
4. For higher loads, multiply Accuracy specification by:
accuracy full for load maximum
load actual x 0.1

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:
....................................................... 1 second for mA and mA ranges; 3 seconds for 2.2 A range; 6 seconds
for 11 range; + 1 second for range or polarity change
Overshoot:
............................................................ <5 %
