The property set the electric meter fast.

It is impossible for a regular watch factory to produce this kind of adjustable watch.

There are strict standards for the design and manufacture of electric meters, which are mainly formulated by the State Grid under the supervision of relevant departments.

If we can adjust the speed, it will be a huge loophole for both the supply and demand sides, resulting in market chaos.

So go back to the question of whether the watch you are using is accurate.

You can use a relatively stable load, such as 1000 watts, and walk for 0. 1 6 minutes for preliminary test.

If you find that the form is wrong, you can apply for verification.
