  • This device is a new generation of highly intelligent single-phase energy meter calibration device developed using the latest technology. All its indicators are better than the technical requirements of the national standard "GB11150-89" and the national metrology verification regulations "JJG597-89". It can calibrate and verify single-phase AC induction energy meters and electronic energy meters below level 0.5. Please read this instruction manual carefully before using this device.

    This device has the following outstanding features:
    1. This device integrates standard table and standard source into one, with high technical integration. At the same time, it adopts a large-screen LCD display and Chinese menu operation prompts. The operation is highly intelligent and extremely simple to use. It can detect three single-phase energy meters at the same time.
    2. It has the automatic tracking and locking function of voltage and current, so that the voltage and current output have the function of a standard source, with high output stability, small waveform distortion, good power factor characteristics and high accuracy.
    3. The load point test, starting and creeping tests all have manual and automatic calibration functions. During starting and latent motion tests, the color mark is automatically positioned to automatically determine whether it is qualified or not, saving time and effort.
    4. It has a removable large-capacity memory that can store input parameters and calibration results of 800 electric energy meters, so that the calibration results do not need to be recorded with a pen and can be recalled from the device for inquiry at any time.
    5. This device is equipped with an RS232 standard computer serial communication port, which can transmit data to the computer for data management through the RS232 serial port.
    6. When setting parameters, it has a powerful input error checking function.
    7. It has the characteristics of small size, light weight and beautiful appearance, which truly reflects the superiority of the portable single-phase electric energy meter calibration device.
