12 factors affecting the accuracy of electronic crane scale

As an electronic scale, the accuracy of the electronic crane scale is extremely important. But sometimes the accuracy of the electronic crane scale will be affected. So what are the reasons that will affect the accuracy of the electronic crane scale?

12 major factors that will affect the accuracy of electronic crane scale:

Various errors should be tested under standard test conditions. When determining the effect of one factor, all other Impact Factor\'s should also remain stable near normal values.

1. Elimination of rounding error—any rounding error included in the numeric indication must be eliminated.

2. Allowed error of net weight value - allowable error applies to the net weight value after tare, except for the preset tare value.

3. Distribution of errors - During the individual test of each module of the gr.ue electronics, error distribution shall be carried out in accordance with the provisions of 4.4.4 in JJG555-1996.

4. Testing during verification—the electronic crane scale under test must be tested for the whole machine.

5. Allowable error between weighing results - no matter how the weighing result changes, the error of any weighing result shall not be greater than the allowable error of the weighing.

6. Repeatability—for the same load, the difference between multiple weighing results should not be greater than the allowable error value of the weighing.

7. Rotation - After the load is lifted vertically and rotates at any angle within the horizontal range of 360°, the error of the indication value shall comply with the provisions of 5.1.1.

8. Multiple indicating devices—the difference between the different indicating devices of the electronic crane scalee and the printing device should be zero.

9. Calibration standard device - the error of the standard device used to check the electronic crane scale shall not be more than one third of the corresponding allowable weighing error of the scale at electronic crane. Standard weight substitution shall be in accordance with the provisions of 5.6.2 of JJG555-1996.

10. Discrimination—When gently placing or removing the 1.4e weight on the hook or other support of the electronic crane scale in a balanced state, the original indication value should not to change .

11. The amount of change caused by the amount of influence and time - the electronic crane scale must meet the requirements of 6.1, 6.2, 6.4 and 6.5.3.

12. Temperature—If no special operating temperature is specified in the product specification, the electronic crane scale must maintain its measurement performancein the temperature range of -10 to 40°C. The special working temperature range should not be lower than 30°C.
