Why do you need to do a cleaning job after each
measurement?
Because infrared temperature
uses a
highly sensitive
technique to detect the temperature of the target object,
not only will any earwax
or
dust affect the measurement
accuracy,
but it is
more likely to cause
a
bacteria
infection. So we suggest that you cleaning
as
well as
the
diagram
shows after
each use.

read the value and remind at this moment.(A short beep will be heard.)
Err
When the environment
temperature changes rapidly
about 5 degrees, it will show
“ Err ” during measurement
in object temperature mode,
then shutdown automatically.
When it shows “Err”, please place
this product and keep steady in
current environment for 30 minutes
before next measurement.
