The medium time for operations is 4 seconds for monophase meters and 12 seconds for polyphase meters, the daily productivity is 16.800 and 5.600 pieces in 22 working hours and the efficiency is higher than 85%.


The process for assembly, test and calibration is structured as follows:

  • Cycle start/components checking

  • Base placing on conveyer belt

  • Tamper contacts mounting/protections screwing

  • Power groups mounting

  • Breaker mounting

  • Board mounting and cables soldering

  • Case mounting

  • Test

  • Calibration (followed by verify)

  • Laser marking

  • Meters sealing

  • Line unloading
