Detailed Description

The technical solution of the present invention is further explained below with reference to specific embodiments:

as shown in fig. 1, the utility model discloses establish a multifunctional electronic scale, including the balance body 1, pressure sensor 2, display element 3, measurement control unit 4, clock unit 5, speech unit 6, its characterized in that, be provided with level detection unit 7 and inclination detecting element 8 on the balance body. The pressure sensor 2, the inclination angle detection unit 8 and the clock unit 5 are connected to the input end of the measurement control unit 4, and the display unit 3 and the voice unit 6 are connected to the output end of the measurement control unit 4.

The scale body 1 is provided with a horizontal detection unit 7. Before weighing, the level detector 7 on the scale body 1 is used to detect the level state of the scale body, the level detector 7 of the embodiment is composed of

level rulers

71 and 72, the

level rulers

71 and 72 are glass tubes filled with water and sealed with one bubble, and the

level rulers

71 and 72 are vertically arranged near the frame of the scale body. By observing whether the bubbles in the

level rulers

71 and 72 are in horizontal positions or not, if the bubbles are in the middle positions, the scale body 1 is in a horizontal state; if the air bubble is not in the middle position, the scale body 1 is not in the horizontal state. In this case, it is necessary to adjust the horizontal state of the scale body 1 by changing the placement position of the scale body 1 or the level of the support table, and then observe the position of the bubble in the leveling

rulers

71 and 72, so that the horizontal state of the scale body 1 is repeatedly adjusted until the bubble is at the middle position, that is, the scale body is in the horizontal state and then weighing is performed.

On the contrary, according to the same principle, the level detection device on the scale body can be used for judging whether the supporting platform surface is level or not.
