Mode Of Operation
Local Mode Through front panel potentiometer for voltage, current
and
over voltage and Push switch for Output ON/ OFF control.
Remote Mode Interface Analog programming of voltage
and current.Voltage: 0 - 5 volts or 0 – 10 volts for output
voltage and current, selection through DIP-switch.
Resistance: 0 – 4.85k ohms from 0 to full-scale level.
* = Specification also apply to corresponding GPIB model
F.S = Full Scale. Full scale will be different for each model. Example: If you have a VSP2030
and you are measuring the voltage meter accuracy, the meter can not offer more than 0.3V
(20V + 0.2% +3 digit). Note: 3 digits refferes to the power supply displays least significant
digit.
Digital Interface RS-232 / GPIB
