1. Never apply voltage (e.g. engraving with an electric pen) on any part of the Digital Micrometers for fear of damaging the circuit.
2. Press the ON/OFF button to shut the power when the Digital Micrometers stands idle; take out the battery if it stands idle for a long time.
3. As for the battery, abnormal display (digit flashing or even no display) shows a flat battery. Thus you should push the battery cover as the arrow directing and then replace with a new one. Please note that the positive side must face out. If the battery bought from market doesn’t work well (the power may wear down because of the long-term storage or the battery’s automatic discharge, and etc.), please do not hesitate to contact the supplier.
4. Flashing display shows dead battery. If this is the case, please replace the battery at once. No displace shows poor contact of a battery or short-circuit of both poles of the battery. Please check and adjust pole flakes and battery insulator cover. In case water enters the battery cover, open the cover immediately and blow the inside of the battery cover at a temperature of no more than 40°C till it gets dry.
