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.
1. Add to uncertainty specifications:
±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.
4.For higher loads, multiply uncertainty specification by:
1 + | 0.1 x actual load |
|
maximum load for full accuracy
5. 5700A compliance limit is 2V for outputs from 1A to 2.2A. 5725A Amplifier may be used in
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
Overshoot: <5%
