The 332B DC Voltage Calibrator is ideal for any situation that requires accurate DC voltages. The output voltage ranges from 0 to 1111.1110 VDC and is set by seven in-line decade switches to provide 0.1 ppm resolution. The output current ranges from 0 to 50 mA. The 332B has a basic accuracy of ±0.002% and a stability of ±0.001%/month. Other features include overvoltage and overcurrent protection and guarded operation.
