The working principle of the alcohol tester: when the gas sensor cannot detect alcohol, the level of the 5th pin added to A is low leve.
When the gas sensor detects alcohol, its internal resistance becomes low, so that the 5-tube of A pin level goes hig.
A is a display pusher, it has 10 output terminals, each output terminal can drive a light-emitting diode, the display pusher A determines the number of stages to light up the LEDs in turn according to the level of the 5th pin, the higher the alcohol content The larger the number of stages that light up the diodes i.
The top 5 LEDs are red, indicating that the level is exceede.
The bottom 5 LEDs are green, indicating the level, and the alcohol content does not exceed 05.
Alcohol testers are mainly used in the transportation industry, underground mining, et.
What everyone often sees is the alcohol tester in the hands of traffi.
Matters needing attentionDuring the test, press and hold the POWER button of the power switch and do not let g.
If it is not used for a long time, the red light or yellow light will be lit for a long time during the tes.
If a similar situation occurs, please press the POWER button of the power switch to try several time.
If the battery power is insufficient, the red and yellow lights will be on for a long time at the same time during the tes.
Please replace the battery at this tim.
Do the test after drinking alcohol for at least 20 minutes, as it takes about 20 minutes for alcohol to be absorbed from the digestive system into the bloodstrea.
Tested immediately after drinking, the results can only reflect the alcohol concentration in the mouth at that time, not the alcohol concentration in the bloo.
In order to make the test results more accurate, the test time should be more than 3 minutes from the last tes.
Smoking and eating are strictly prohibited within 20 minutes before the tes.
Do not use chemicals to clean the tester directly to prevent liquid from flowing into the blowpip.
It is strictly forbidden to place and use paints, pesticides, alcohol and other accessorie.
