Applications
DC voltage calibrators of this type are used in metrology labs, service facilities, and manufacturing test departments to calibrate and verify the accuracy of digital multimeters, analog meters, and data acquisition systems. The 472A was commonly deployed in electronics service centers and industrial calibration operations to maintain traceability standards for electrical measurements.
This Precision Standards Corp 472A DC Voltage Calibrator is being sold as-is for parts or repair. The unit came from the closure of Beckman Industries' calibration laboratory in Southern California. It was not tested at our facility and no functionality is guaranteed. A handwritten technician's note found with the unit (dated 9-8-17) indicates that at zero on the dials it read 0.1 millivolts rather than the expected zero, and that the unit otherwise needs calibration — suggesting it was last evaluated by calibration staff before the lab closed. Cosmetically, the instrument appears to be in fair condition with age-appropriate patina and wear consistent with vintage lab use; the front-panel binding posts, decade knobs, polarity switch, and power switch are all physically intact. A rear service label from Berkeley Instruments Inc. of Santa Ana, CA is present. An output cable with alligator clip is attached to the rear.
