The transducer type are the verification, AC/DC voltage transducer, current transducer, single/three-phase active, reactive power transducer, phase transducer, a power factor transducer, frequency transducers.

Verification of watt-hour meter can be species are: electronic type and inductive single-phase and three-phase meritorious electric energy meter and reactive watt-hour meter.

To set and measuring 2 ~ 31 times harmonic.

Wide measuring range, high stability, high resolution, low distortion degree.

Automatic data about the certificate format have various forms, convenient inquires the and print

Through the computer control, it can realize the automatic verification watt-hour meter and transducer, semi-automatic verification all kinds of instruction machine

It is block structure, facilitate inspection, and it can be used independently

Automatic failure detection, can prevent the damage of equipment wrong operation

Many kinds of models the device preset portable instrument parameters, reduce the verification personnel the input workload.

Standard meter, communication standard resource, dc standard resource are software calibration, simple to use, it is stable and reliable.
