Gravity
The two forces that compress a spring inside a weighing scale are the force of gravity acting on the person standing on the scale and the reaction force exerted by the spring in the scale to counteract the force of gravity. This compression of the spring is used to measure the weight of the person.
When the man pulls on his shoelaces while standing on the scale, the scale reading will not change. This is because the force he is exerting by pulling on his shoelaces is an internal force within his body and does not affect the normal force acting on him from the scale. The scale measures the normal force acting on the man, which is equal to his weight, regardless of any internal forces he may be exerting.
Gravity and Support Force
Philipp von Jolly invented the modern weighing scale in 1874.
Weighing scale is called "秤" (chéng) in Chinese.
It is 20 N.
The name of the creator of the first weighing scale is lost in antiquity. The most ancient relics of a weighing scale date back to around 2,000 B.C.

You can use an accelerometer to measure the gravitational force that pulls something else towards the center of the Earth. Accelerometers detect changes in acceleration, including the acceleration due to gravity.
The sum of the scale readings will always equal your total weight.
Balance Scale
A weighing scale itself is not heavy, as it is designed to be easily movable and transportable. The weight of a weighing scale can vary depending on the type and size, but typically they are lightweight and can be easily carried by hand.
