1, plus a possible protective cover, and promptly clean spattering eat and cutting

oil, strictly prevent any foreign matter into the sensor housing inside grating.
2, periodically check the mounting screws are loose coupling regularly with a dry

clean cloth table.
3, grating displacement sensor vibration and beat non-violent stampede to avoid damage to the grating, such as broken grating, grating

sensor that is ineffective.
4. Do not disassemble themselves grating displacement sensor, but can not

change any of the main scale and the sub-grid scale Shan relative pitch, otherwise the one hand, could undermine the

accuracy of grating sensor, on the other hand it may also cause the main gate

and the subgrid scale relative friction feet, damaged chromium layer will damage

the gate lines, resulting grating scrapped.
5, should be taken to prevent water pollution and whether the hard object to

scratch the surface grating, so as not to undermine grating streaks distribution,

measurement errors
6. grating displacement sensor should try to avoid working in severe corrosive

effectof the environment, to prevent corrosion of the chromium layer and the

grating surface grating, grating mass destruction.
