Features:
1.The device is a portable integrated design, exquisite craftsmanship, beautiful and generous;
2.The device can compare various mechanical and electronic single-phase electric energy meters;
3.The device can compare the power consumption of the electric energy meter in the following ways:
a.Timing: Set a certain comparison time, the test will automatically stop when the time is up, and compare the power of the word run between the tested meter and the standard meter at the same time;
b.Quantitative: Set a certain amount of comparison power, stop the power supply of the tested meter when the standard is expressed to the set power, and compare whether the power of the tested meter is consistent with the setting;
4.The device can be used in the laboratory. When the device is used in the laboratory, the device is equipped with special software, and the electric energy meter can be checked and tested in accordance with the relevant national inspection regulations;
5.The device supports the on-site verification function, and can conduct the start-up, creeping, basic error and other tests of the single-phase electric energy meter in accordance with the requirements of the national measurement regulations.
6.On-site operation supports manual operation verification of the tablet Android system APP, and Bluetooth communication mode.
7.The laboratory operation supports the automatic verification of the PC Window system software, and the standard serial communication method.
8.At the same time, it supports simple data printing and standard A4 paper detailed data printing.
