The measuring surface must be wiped clean before use. The caliper measuring surface, LCD display and other transmission parts should be kept clean. After measurement, the measuring claw should be closed to prevent dust, sand, metal chips and other objects from damaging the transmission parts.2. The measurement of the workpiece should be carried out in a static state. When using it, the measurement force should be appropriate. The caliper with a micro roller should use a micro roller.3. The moving caliper frame should be stable, avoid rapid pulling to the tail end or front end and collision, and avoid bumping and falling to prevent circuit failure, induction failure, LCD and measuring claw and other parts damage.4. It is forbidden to drop the caliper close to the magnetic field or place it on a magnetic object. If the caliper is found to be magnetic, it should be demagnetized in time before use.5. Special attention should be paid to the use of electronic calipers: it is necessary to avoid contact with liquid substances such as water. During use, when the displayed number flashes or does not display, a new battery of the same specification should be replaced. Do not apply voltage to any part of the caliper, and do not use an electric pen to engrave, so as not to damage the electronic components. If the digital display cannot count (the digital is locked), it should be a product due to accidental factors in the circuit, which is a normal phenomenon. At this time, remove the battery and reinsert it after 23 minutes.6. Non professionals cannot disassemble the transmission part of the caliper, and the caliper must be checked regularly
