Digital Confusion - There are three main reasons.
A. The surface of the protective film is wet or stained with a cutting fluid (or other conductive particles).
Treatment: Wipe the ruler and protective film surface with a dry cloth and slightly damp with ethanol or aviation gasoline. A small drop of absolute ethanol or aviation gasoline that slowly twists (please be careful not to drip too much, otherwise liquid will enter into electronic components that cause other problems! )
B. Copper clambling under the protective film is affected by corrosion and blacking.
Therapeutic method: discover protective film and polish and clean the surface of the copper strip with premium rubber or metal inspection paper.
C, Battery is not sufficient - Treatment: Replace a new battery.
