The existing verification method mainly adopts manual handling to carry the standard weights to the bearing surface of the mechanical scale to be verified, and read the display value of the mechanical scale. If the error between the display value of the mechanical scale and the standard weight is within the allowable range, it indicates that the scale reading is accurate.
[0003] During the calibration process, a certain number of standard weights need to be manually carried to complete the corresponding calibration work such as zero point, weighing test, repeatability, overload and sensitivity; if a calibration item of the mechanical platform scale does not meet the requirements, it needs to be repaired and adjusted before calibration. In this process, the standard weights need to be removed again, but manual handling of weights is labor-intensive, inefficient, time-consuming and labor-intensive; a single weight is too heavy, and the measurement personnel need to bend down for many times to carry it, which is easy to sprain the waist and inconvenient to operate.

[0022] The support frame 1 has four support legs, and pads are installed at the bottom ends of the four support legs. As an optional technical solution of the utility model, this makes it easy to stably place the support frame 1 on the ground.
