1, the thickness gauge belongs to the precision gauge, and should prevent the impact and fall, so as to avoid the loss of precision.
2, should keep clean, avoid water and other liquid substances into the gauge gauge in order to avoid the effect of normal use.
3, do not use the data output port, the output will not cover off, don't touch the output with a metal device with arbitrary, so as not to damage the electronic circuit.
4, any part of the gauge can not be applied voltage, do not use a pen to engraving, so as not to damage the electronic circuit.
5, the battery should be removed when it is not used for a long time.
