Also, with an adjustable voltage source, the voltage dependence of the resistance under test can be obtained directly.

而且，使用可调的电压源，还可以直接得到被测电阻对电压的依赖关系。

Undervoltage Sensing for Each Phase of Normal Source: pickup voltage is adjustable form 85 to 100 percent of nominal, and dropout voltage is adjustable from 75 to 98 percent of pickup value.

正常源每一相位的欠压传感：起始电压可在额定值85 - 100%的范围内调节；回动电压可在始动值75 - 98%的范围内调节。

When nonlinear loads, such as adjustable speed motor drives, affect a sinusoidal power source, the voltage waveform is distorted and becomes nonsinusoidal.

当加上非线性负载如调速电动机驱动器时，会影响正弦电源。电压波形畸变变成非正弦波。
