Instructions:
Press and hold the ON / OFF key for 3 seconds to turn on the tester and go into about 10 seconds warming up. Starting to exhale(continuous exhale 3 to 6 seconds to go into 5 seconds' response time, the test results will display on the LCD at the same time, then it will automatic shutdown after 5 seconds.) when the screen display BIOW. During the test, don't need any other operation, just blowing and reading.
Works Principle:
When the gas sensor does not detect it, the level plus to A in the 5 pin is low, and when the gas sensor detects it, the internal resistance of the sensor becomes low, so that the 5 pin level of A becomes high. A is the display pusher, it has 10 outputs, each output can drive a light-emitting diode, the display pusher A according to the level of the 5 pin to determine and light up the light-emitting diodes in order, the higher the content, the more of lighting the diode numbers. The top 5 light-emitting diodes are red, indicating that the safety level is exceeded. The following 5 light-emitting diodes are green, indicating the safe level, contents are not more than 0.05%.
