Specifications
* = Specification also apply to corresponding GPIB model (Add GPIB to the model number for a GPIB interface instead of a RS232 interface. Example: VSP6020GPIB)
F.S = Full Scale. Full scale will be different for each model. Example: If you have a VSP2050 and you are measuring the voltage meter accuracy, the meter can not off more
than 0.3V (20V + 0.2% +3 digit). Note: 3 digits refers to the power supply displays least significant digit.
