    SECTION 8 CALIBRATION SECTION 8 CALIBRATION CALIBRATION This section describes calibration of a UPC. To fully calibrate the SYSTEM for output voltage and metering accuracy, it is necessary to perform a complete EXTERNALLY REFERENCED CALIBRATION. The Exterally Referenced Calibration requires NO manual adjustment or access of internal circuits. Externally Referenced Calibration achieves high calibration accuracy of the oscillator and metering circuits.
  • Page 120 SECTION 8 CALIBRATION EXTERNALLY REFERENCED CALIBRATION (cont’d) Since the UPC display can show both PROGRAM (Command) and METERED voltages, these errors will be apparent - if they occur - as a slight difference between the two voltages. Only basic metering inaccuracy will not reveal itself on the display.
