A general procedure for electrical calibration

Electrical calibration implies that the results from a device measuring an electric magnitude with unknown accuracy are compared with the values provided for a device (calibrator) whose uncertainty is known. This calibrator is universally accepted as "reference" and traceable to international standards. The main actions in electrical calibration are:

• assessment of calibration capability.
  
  
• switching on and stabilizing the instrument under calibration.
  
  
• instrument initial verification and troubleshooting.
  
  
• setting operational parameters and interconnection.
  
  
• calibrator adjustment.
  
  
• calibrator control.
  
  
• calibration measurements.
  
  
• quantification of the uncertainty of the results.
  
  
• reporting the results and issuing a calibration certificate.
