The Reference Standard is the single- and three-phase version of precision meter for electrical power and energy measurement. The Reference Standard is designed to meet all requirements put on a reference standard in a single- and three-phase electricity meter testing and calibration systems. The Reference Standard can be set to any real or artificial mode of operation in three phase system and is capable to evaluate the individual quantities per phase and the three-phase cumulative quantities as well.

Reference Standard is based on precision 24-bit A/D conversion and digital signal processing technology enabling accurate evaluation of all main and informative quantities. Beyond measurement of all kinds of power, voltage, current and phase, the meter measures the harmonic content and distortion of the input signals.

The meter constant of Reference Standard generating value-proportional impulses on the frequency output is free programmable. This unique feature along with the extremely high maximum output frequency exceeding 2 MHz allows precision error evaluation of tested meters even at shortest integration period. The impulse output can be assigned to various quantities. Additionally, the impulse output can be set to generate any precise constant frequency for testing purposes.

The Reference Standard is equipped with three fully independent differential voltage input circuits. Therefore the meter can be configured to evaluate signals on three independent channels. This feature in combination with possibility to assign the impulse output to any combination of the input channels enables to use the device for example in single-phase system with one channel as reference while the free channels can monitor additional information like power consumption of the current and voltage circuits or contact error in the test circuit.
