Internal dirt: The lens of the internal probe is an important
device. Do not touch or press with your fingers or other
objects, otherwise it will affect the preparation of the
measured value. When the lens surface is found to be dirty,
wipe the lens surface with a cotton swab moistened with 95%
or more absolute alcohol.
Tip: Do not use 75% disinfectant alcohol to wipe the lens
(there will be traces of residual water). Do not use other
chemical wipes to wipe the lens (which will cause damage to
the lens).
Storage: Keep in a dry and dark place out of direct sunlight.
It is recommended to practice several times to become
