It also introduces a method according to the actual situation to put a fixed resistance combination of potentiometer, and it improved the accuracy of circuit.
本文还介绍了一种根据实际情况把电位计和固定电阻结合的方法，提高了电位计在电路中的精度。
Sliding resistance was replaced by the fixed value resistance, and potentiometer was used to adjust volt, it could make measurement of diode reverse characteristic more convenient.
用定值电阻代替滑线变阻器，用分压器调节电压，可使二极管反向特性的测量更加方便。
