Abstract: An automated verification and calibration system (ASPC) for digital voltmeters is proposed, based on the LabVIEW software package, which does not require a personal computer and has the advantages of large verification systems that require more powerful and, therefore, more expensive computers. Also, the advantage of LabVIEW is its versatility, which consists in the fact that by purchasing an ASPC of digital voltmeters, the user receives a software package on which it is possible to implement systems without additional investments. The use of ASPK digital voltmeters is relevant at the present time and has a number of economic and technical advantages over other market representatives in this area. The system is fully capable of fulfilling the main goals laid down during its creation, which are: simplification of the verification process and reduction of time spent on verification of one measuring instrument. The system can work with equipment from different manufacturers, the only condition is that the calibrator has an RS-232 interface. The most suitable equipment for creating an automated workstation (AWS) for verification and calibration of digital voltmeters has been determined, and their connection diagram has been designed.

Key words: verification of electrical measuring instruments digital voltmeters automated verification and calibration system automation of verification operations automation of calibration operations
