1. Does the carbon film resistor have a computer for continuous repair? Current injection molding machines use a servo power-saving control system, which uses closed-loop control for the injection and melting positions. If the carbon film of the electronic ruler has not been repaired, the linear accuracy must be very poor, and it is difficult to ensure injection molding. The power saving effect of the machine and the injection molding effect of the machine. Just take out the carbon film board and observe carefully, there is a thin continuous cutting line next to the carbon film board that has been repaired by the computer. The carbon film board that has not been continuously repaired and engraved by a computer is to use a knife to draw a few intermittent lines at will, or there is no repair at all.
2. Is the surface of the brush contacting the carbon film smooth? Regardless of the material used for the brushes, whether platinum, palladium, or gold, we cannot know, and we do not expect to recycle it in the future. The key is to see whether the contact surface between the brush and the carbon film is smooth, and whether it will cause damage to the carbon film. Just feel it with your fingers, a good electronic ruler, the contact surface of the brush is very smooth, will not cause damage to the carbon plate, can reach tens of millions of times of life, while the carbon plate still maintains good linear accuracy.
3. Is the structure of the brush filamentary? A good electric brush must be multi-joint. Even if we flick the wire with our hands, the brush is still intact and will not deform or damage. A bad electric brush will be deformed immediately after flicking it by hand, just like a tooth and a claw. There is no effect of the electric brush at all. Imagine that the brush needs to work millions of times. Can such a sheet-shaped brush guarantee the effect? The electronic ruler is actually a product of conscience.
