求翻译：工厂机器功率没有变更。客人测试的方法不能说明他要表述的问题，因为输出电压的大小是用电位器来调节的，当电位器旋钮的位置不同时输出的电压也是不同的。是什么意思？

Plant machinery power has not changed. Guests test method can not be expressed, because the output voltage of the potentiometer to adjust the voltage output at the same time when the position of the potentiometer knob is different.

There is no change machine power plant. Guests of the test does not indicate how he would like to mention the problem, because the output voltage of the size is a potentiometer to adjust the potentiometer knob position is not with the output of the voltage is different.

The factory machine power has not changed.The visitor tests the method cannot show he must indicate question, because the output voltage size is, when potentiometer knob position which adjusts with the potentiometer different outputs the voltage also is different.

Factory machine power does not change. Guest test methods do not describes him to express problems, because the size of the output voltage is to use potentiometers to adjust when the potentiometer knob's position is not the same as the output voltage is different.
