Main features:

1. Can be used to collect the black signal of the mechanical watt hour meter, and can receive the pulse signal of the electronic energy meter.
2. The use of potentiometer to adjust the level and sampling sensitivity, and by the four LED indicator light, light, strong.
3. Imported receiving tube, strong anti-interference.

Usage method：

1. The red switch, the photoelectric sampler was placed in front of the school table, from the school table surface between about 15--20mm, adjust the upper and lower positions of the center of the beam spot in the middle school table runner is the rightmost counter with bright mark.
2. Adjust the potentiometer, to LED level indicator lights, LED lights up red signal output. The potentiometer to the opposite direction to adjust the output signal of LED without signal just out, signal arrival signal output LED lights (output signal).
3. If the LED level indicator lamp does not go out, the signal output signal indicating no red LED lights, will adjust the internal and external photoelectric sampler distance or position, and then come back to adjust potentiometer.
