The electric parameter of reasonable choice potentiometer, after the type that has chosen potentiometer according to the requirement of equipment and circuit and specification, the electric parameter that chooses potentiometer reasonably according to the requirement of circuit even, include rated power, nominal resistance value, allow deviation, resolution, highest working voltage, move noise to wait. Choose potentiometer according to the law of resistance value change, the voltage adjustment in all kinds of power supply circuit, the working point of amplifying circuit adjustment, deputy brightness adjustment and line, field scan signal adjustment use potentiometer, all should use straight-line potentiometer.

Potentiometer waveform expands according to the time axis, whenever the combination level of P1.0 and P1.1 is 01 00 10 11 in turn four kinds of status code constitute a byte namely 4BH, it represents a left rotation volume minus 1. When the combined level of P1.0 and P1.1 is 10 00 01 11, the four state codes form a byte, namely 87H; That means one right-hand turn plus one volume. Here, “4BH” is referred to as the left-handed one-bit feature code, and “87H” is referred to as the right-handed one-bit feature code. The task of programming is to recognize these two kinds of characteristic codes in the process of pulse potentiometer rotation, and on this basis, to increase or decrease the volume control. Potentiometer actual programming can use different methods to identify these two kinds of characteristic code.
