HD2005 Gas meter photoelectric sampler

Main Features
main feature:
1. Use the potentiometer to adjust the comparison level and sampling sensitivity, which is convenient for light.
2. Adopt imported receiving tube, strong anti-interference.
Corresponding parameter set not found, please add it in property template of background
1. Turn on the red switch, place the photoelectric sampler in front of the calibration meter, about 15-20mm from the surface of the calibration surface, adjust the upper and lower position, so that the center point of the beam is illuminated at the right end of the meter counter. In the middle of the target runner.
2. Adjust the potentiometer, adjust to the level indicator LED is off, and the signal output red LED lights up. Then adjust the potentiometer to the opposite direction, and adjust to the signal output LED when it has no bright mark. When the bright mark comes, the signal output LED lights up (there is signal output).
3. If the level indicator LED does not go out, the red signal LED light has no signal output indication, the optical sampler can adjust the internal and external distance or the up and down position, and then adjust the potentiometer back and forth.
