AI Technical Summary
In the existing technology, when calibrating an electronic balance, it is impossible to place the weights sequentially at each corner of the balance. This results in the balance being in good condition in the middle but inaccurate at the corners, reducing the accuracy of the calibration.
A metrological verification and calibration device was designed. By combining a first guide rod and a second guide rod, the clamping arm can be adjusted laterally and longitudinally. Combined with a locking component and a support component, the weight can be placed at any position on the device to be tested, thereby increasing the accuracy of the test results.
By adjusting the position of the weights in multiple directions, the accuracy of the electronic balance calibration is improved, ensuring the uniformity and consistency of the test results.
