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.

LED heatsinks are cooling devices designed to dissipate heat generated by LED light sources. These heat sinks are essential for the proper functioning and longevity of LED lights, as excessive heat can damage the LED chips and reduce their lifespan. LED heatsinks come in various shapes and sizes, depending on the size and power of the LED light source.The primary function of an LED heatsink is to transfer heat away from the LED chip and dissipate it into the surrounding air. This is typically achieved through a combination of conduction, convection, and radiation. The heatsink is usually made of a thermally conductive material, such as aluminum or copper, which helps to absorb and transfer heat away from the LED chip.There are two main types of LED heatsinks: passive and active. Passive heatsinks rely on natural convection to dissipate heat, while active heatsinks use fans or other cooling mechanisms to increase airflow and enhance heat dissipation. The choice of heatsink type depends on the specific requirements of the LED light source and the environment in which it will be used.LED heatsinks are an essential component of LED lighting systems, and their proper design and installation are critical to the overall performance and longevity of the system. By effectively dissipating heat, LED heatsinks help to ensure that LED lights operate at their optimal temperature and provide reliable and consistent illumination.
