The following should be observed during use: 1. Be sure to wipe both measuring surfaces gently with a shiny surface of folded white paper before use;2. When in use, the fork (or knob) must be rotated repeatedly to complete the zeroing process, and the bezel must be rotated to find the zero position;3. Put the measured object into the upper and lower measuring drills (heads) and tighten them firmly, and the pointer reading value is the thickness of the measured object; 4. When measuring plastic films, electrostatic induction will be generated during the film production process, so after each measurement It is also necessary to wipe both measuring surfaces with a shiny surface of folded white paper;5. Excessive impact and touching are not allowed during use;6. Except for normal maintenance, it is not allowed to arbitrarily disassemble parts (including the special indicator and the upper and lower drill bits), so as not to affect the measurement accuracy;7. Re-inspection of the product shall be inspected in accordance with the inspection methods and rules of the product standard, and the technical correctness of the indicator table is no longer inspected separately;8. After use, wipe the measuring surface and put it in the box;
