ASTeL 1.2 meter test equipment is a fully automatic system that enables simultaneous, multi-position calibration and verification of single-phase electric energy meters. ASTeL 1.2 offers full compatibility with IEC 60736. Thanks to excellent parameters, superior functionality and outstanding flexibility, ASTeL 1.2 is an ideal solution for utility companies, energy meter manufacturers, governmental institutes of metrology, metrological laboratories, and other customers interested in electricity meters testing.


ASTeL 1.2 is designed for testing a diverse range of electric energy meters. Those include but are not limited to:

  • active and reactive energy
  • electromechanical (also with impulse outputs) and electronic
  • with closed I-P links
  • multi-tariff, up to 16 tariffs
  • multifunctional and multi-quadrant with active/reactive energy/power  registers
  • prepaid meters
  • smart meters with data communication
  • reference standards, portable and stationary multifunction multimeters etc.

Support for customer’s specific meters can be added upon request.


ASTeL 1.2 enables performing tests as required by international standards. Those include but are not limited to:

  • basic error (accuracy test)
  • starting current
  • no-load run
  • testing energy registers (dial test) and maximum demand indicator
  • constant test
  • checking the maximum demand registers (electromechanical or electronic)
  • checking the pulse outputs
  • pre-heating
  • testing the influence of frequency, harmonic distortion, voltage, current and other parameters on meter under test error

Customer’s specific tests can be added upon request.


ASTeL 1.2 is a modular construction. Major parts of the system include:


Single phase power sources with different output powers and different harmonics ability are available. Read more


Single phase reference standards with accuracy 0.04, 0.02 and 0.01 are available. Read more
