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。
Set the test set to on and adjust the RANGE and SETTING controls until you get a current of 1ma on the multimeter.
接通测试装置并调节RANGE和SETTING控制旋钮，直到在万用表上得到1毫安的电流。
Changing the measurement range usually changes the test current as well.
改变测量量程通常也就改变了测试电流。
