The distance between the user's mouth and the blowing opening
should be less than 3 cm during the test, so the air is not diluted and
the result will be more exact.
6.5 TEST RESULT DISPLAY TIME setup
The display time is how long the result will appear on the screen. To improve the
performance and efficiency of the breathalyzer, the result will be shown during a brief
period of time (which may be modified). The breathalyzer will then automatically return
to the test mode to continue with the tests. If this auto-return function is not required, you
may set the display
time to “unlimited”. In this case, the result of the test will appear until
you press any button. You will then return to the test mode.
Press the left button
to select how long you want the result displayed. Press the
right button
to save the change. Press
after setting the value to exit the
display time menu. If the value has been changed, it will be automatically saved when
you exit the menu. The save interface will appear as a reminder.
