Because of the low test current level used, a very sensitive voltmeter is required to measure the voltage drop, which is usually in the microvolt range.

由于所使用的测试电流很低，所以就需要非常灵敏的电压表来测量这种通常在微伏范围的电压降。

Supply voltage should be controlled at not more than or less than 5% of rated voltage range, if the voltage too high or too low will damage motor.

电源电压应控制在不大于或小于额定电压的5%范围内，如果电压过高或过低都会损坏电机。
