<nrf> command.Autorange On: 10ms. Autorange Off: 7ms.
OUTPUT SETTLING TIME: Time required to reach 0.1% of final value af ter command is processed. 100 s typical. Resistive load. 10 A to 100mA
range, 1V step.
OUTPUT SLEW RATE: 0.25V/ s –30%, 100V range, 100mA compliance. 0.08V/ s –30%, 20V range, 100mA compliance.
COMMON MODE VOLTAGE: 250VDC.
REMOTE SENSE: Up to 1V drop per load lead.
COMPLIANCE ACCURACY:For Source mode, add 0.1% of range to base specification. For Sink mode, 10 A to 100mA range, accuracy is –(0.5%

Additional Pulse Mode Source Specifications
MAXIMUM DUTY CYCLE: 8%, hardware limited, 10A range only. All other ranges 84%.
MAXIMUM PULSE WIDTH: 5ms from 90% rising to 90% falling edge, 2.5ms 10A range.
MINIMUM PULSE WIDTH: 150 s, with 0.004 PLC measurement.
MINIMUM PULSE RESOLUTION: 10 s typical, 20 s max., limited by system jitter.
SOURCE ACCURACY:Determined by settling time and source range specifications.
OUTPUT SETTLING TIME, 0.1%:
800 s typ., source I = 10A into 10 , limited by volt age slew rate.
500 s typ., source I = 10A into 1 , limited by volt age slew rate.

1
S pecifications valid for continuous output current s below 105mA. For operating above 105mA on the 1A range for >1 minute, derate accuracy 10%/100mA
above 105mA. For operating above 105mA on the 3A range for >1 minute, derate accuracy 10%/300mA above 105mA.
2
Full power source operation regardless of load to 30 C. Above 30 C and/or power sink operation, refer to the Power Equations section of the User s Manual.
For power line volt ages less than 95V, limit max. current to 0.85A on 1A range and 2.5A on 3A range.
