The areas where magnetic grid rulers are prone to problems

Areas where magnetic grid rulers are prone to problems:

1. Most of the problems with magnetic grid rulers lie in the reading head, one is caused by component aging and the other is mechanical wear or component detachment caused by moving parts;

2. Do not attempt to clean the magnetic components on the reading head with anything, especially organic solvents, as this may exacerbate the aging of the circuit board and damage the coating on the lens;

3. The main body of the magnetic grid ruler may also have issues. If the magnetic grid ruler body is installed improperly, such as excessive water level and vertical errors, the accuracy of the magnetic grid glass will be lost after a long period of time. In addition, the magnetic grid glass may have cracks or gaps. If it's broken, if the damaged part is on an unused magnetic scale, it can still be used. If it is in the necessary position, a new ruler must be replaced. When impurities such as iron filings enter the ruler, reading will be unprepared.

4. For each magnetic grid ruler installed, the ruler body must have both horizontal and vertical sides, with the short ruler controlled within 10 rows and the long ruler controlled within 20 rows. If the instrument is inaccurate, it will not only affect the accuracy of the ruler, but also the service life of the ruler.

5. The maintenance of magnetic grid ruler is a meticulous task. All preparation work should be completed in advance, including technical consultation, component selection and configuration, maintenance, and lighting treatment in pollution prevention. This is indeed a work where success depends on details.
