The Xitron 2000IN is a lightweight DC power source instrument. Its capabilities include the generation of precision bipolar DC voltages and precision bipolar DC currents. You may enter a scaling factor, an offset factor, and a "units" text string, which enables the calibration of four 20mA loops in the "actual" units and scaling of the transducer. Optional IEEE488 isolated interface further enhances this instrument. The combination of HCMOS microprocessor technologies with low-power precision analog circuitry yields a long battery life while maintaining a lightweight rugged package and a 0.5ppm analog output resolution. Automatic internal calibration and simple front panel (covers on) external calibration maintain high accuracy. A comprehensive range of computational abilities enables a variety of applications.
