The model 3330A Programmable Constant Current-Constant Voltage Calibrator is a dc calibration instrument which produces output currents from 0 to 111.1111o milliamperes and output voltages from 1 to 1111.1110 volts dc. Output current selection is also available in thress ranges and is accurate to within 0.01% of teh selected range. Output voltage selection is also available in three ranges and is accurate to within 0.005% of the selected range. Over current and voltage protection features are also provided, thus preventing harm from occuring to devices being tested with this instrument.
