In resistance tester circuit, it is necessary to adjust the potentiometer to balance the resistance tester. Under the influence of temperature, humidity and vibration impact, the position and specifications of the potentiometer will be changed when being used,  the system index is also changed. Therefore, to make the system back to the original state it needs to be adjusted, and digital potentiometer module can just solve this problem.

The digital potentiometer changes in steps or incrementally, and the resistance is of linear change. For example, the resistance range of X9C104 is 40R~1000k,  divided into 100 steps, so each increment is 1010R.
