All Models
Voltage Setting: By floating point numeric entry or rotary jog wheel; resolution 1mV.
Current Setting: By floating point numeric entry or rotary jog wheel; resolution 1mA or
0.1mA depending on range.
Setting Accuracy: Voltage - 0.03% ±5mV. Current 0.2% ±5mA/0.5mA
Output Mode: Operation in constant voltage or constant current modes with
automatic cross-over and mode indication by LEDs.
DC Output Switch: Sets output voltage and current levels to zero when Off.
Output Terminals: 4mm safety binding post terminals on 19mm (0.75”) spacing.
Duplicated on rear terminal block (P versions only)
Load Regulation: For any load change, at the output terminals, using remote sense.
Voltage <0·01% + 2mV.
Current <0·01% + 250µA; <0.01% +50µA on 500mA range.
Add typically 2·5mV for a 0·5V drop in the positive output lead.
Line Regulation: Voltage <0·01% + 2mV for 10% line change.
Current <0·01% + 250µA; <0.01%+ 50µA on 500mA range
Ripple and Noise: Typically <0.35mv rms="" cv="" mode="" and="" 0="" 2ma="" rms="" ci="" mode="" br=""> (<20µA rms on 500mA range)
Common Mode Noise: <4ua rms="" at="" 20mhz="" bandwidth="" br=""> Transient Response: <20usec to="" within="" 15mv="" of="" setting="" for="" 90="" load="" change="" br=""> Temperature Coeff.: <(50ppm+0.5mV)/ oC (voltage), <(100ppm+1mA/0.1mA)/oC (current)
Remote Sense: Eliminates up to 0.5V drop per lead. Remote sense operation selected
from front panel and indicated by LED
Sense Terminals: Recessed sprung sockets for direct insertion of wires
Duplicated on rear terminal block (P versions only)
