The electronic balance is the most commonly used weighing apparatus for scientific research institutes, universities and other laboratories. Experiments require high performance and accuracy of electronic balances. How do you evaluate and test the merits of an electronic balance? The following three aspects are used to test the overall performance of the electronic balance:
First, the first is the mechanical part of the electronic balance :
â— Switch check: Check carefully whether there is too tight, too loose, eccentric shaft rotation is not less than the lowest point or beyond the lowest point.
â— Inspection of the electronic balance beam section: Check whether the agate blade has wear, feel and balance. Check whether the sliding buckle is present or not. Check whether the pointer is vertical to the horizontal. â— Inspection of the column part (verticality of the column, leveler, base plate)
Secondly, check the optical system of the electronic balance â— Check whether the screen is normal: no light, no strong light, black or red light or strip light â— The light bulb is normal light: not too bright, not bright enough, or long light.
â— The scale is normal: the sharpness of the scale, the scale cannot be seen, the scale is tilted or bent.
Third, the final inspection of the electronic balance measurement performance
Use two full weights to compare the deviations of the electronic balance. After the two full weights are exchanged, the weight difference is eliminated and the deviation of the balance is calculated. If the bearish zero is changed, it depends on whether the empty weight and total weight are equal. Consistent.
