They typically include data acquisition systems, power quality analyzers, oscilloscopes, and multi-function meters.

[0003] An existing electric meter testing platform (publication number: CN221124859U) has at least the following disadvantages: the device tests the electric meter by fixing the electric meter, plugging the driving wire into the electric meter at the same time and supplying power to the electric meter. However, after testing the electric meter, the device needs to manually dismantle the electric meter and install a new electric meter before testing the next electric meter, resulting in the device being unable to test the electric meter continuously, affecting the test efficiency. In addition, since the installation position of the electric meter is close to the test wire, there may be safety hazards when the staff dismantles the electric meter. For this reason, the present utility model is proposed. Utility Model Content

Then the lifting frame 201 is reset, and the placement plate 204 is rotated one hundred and eighty degrees. The staff removes the tested electric meter and installs and positions the new electric meter, and so on to complete the continuous electric meter test. The limit rod 4 can limit the lifting frame 201, so that the lifting and lowering of the lifting frame 201 is more stable. The directional wheel 5 can support the placement plate 204, so that the rotation of the placement plate 204 is more stable. By setting the placement plate 204 to an acrylic plate, an insulating effect can be achieved to prevent accidental leakage of the equipment from injuring the staff. By setting the thickness of the placement plate 204 to 20 to 30 mm, the strength of the placement plate 204 can be guaranteed to prevent the placement plate 204 from being too thin and causing a certain degree of bending towards the front and rear ends, affecting the testing work of the electric meter.
