Electronic truck scale calibration

In some cases, the electronic truck scale needs to have a high calibration accuracy, and it must consider the correction of the mechanical error. Therefore, the use of load-free calibration cannot meet this requirement. There is a way to accurately calibrate the system using the method of calibration with small weights and substitutes.

Solution one: First, calibrate it with a small weight according to the general calibration method, and get the first one from zero load to a certain weight (weight of the small weight)

The applied range factor a1.

● Add a replacement to a certain weight (display weight is about small weight, this time the scale factor is a1), and then add a small weight to re-calibrate to get a second weight from a small weight to 2 times the weight of a small weight application The range factor a2.

● Add an alternative to display the weight of about 2 times the weight of a small weight, and then add a small weight re-calibration to obtain the second from the weight of the small weight to 3 times the weight of small weight application of the a3.

● By analogy until a certain percentage of the total capacity of the weighing system is achieved, a series of range coefficients are obtained. The appropriate range factor is determined in the meter according to needs, and different range factors may be adopted with different weights.

Note: If too many times can cause cumulative error caused by the weight error.

Scheme 2 ● First calibrate the calibration method with a small weight to obtain the first range factor a1 from zero load to 1/3 of the system capacity.

● Add a replacement to about 1/3 of the system capacity, and then re-calibrate with a small weight to obtain a second range factor a2 from 1/3 system capacity to 2/3 capacity.

● Add an alternative to 2/3 of the system capacity, and then re-calibrate with a small weight to obtain a third range factor a3 from the 2/3 system capacity to full scale.

● Calculate in the meter using the method of segmented range factor.
