Checking commonly used instructions instrument, industrial frequency and DC digital instrument, transducer and electric energy meter, etc.
Checking AC sample device error.
The instrument type are the verification: AC/DC voltmeter, ammeter, single/three-phase active, reactive power meter, phase meter, for access to power, frequency meter, synchronous meter, etc.
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
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
