这些电阻器的阻值应当使其在最大测试电流时的电压降不会影响测量的准确度。
These resistor values should be such that the voltage drop at the maximum measured current will not affect measurement accuracy.
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。
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.
由于安培计上的电压降可以忽略，所以所有的测试电压都出现在电阻R上。
Since the voltage drop across the ammeter is negligible, essentially all the test voltage appears across R.
在使用较大的电流时，这一点特别重要。因为和接点两端的电压降相比，测试引线两端的电压降可能会比较大。
This is especially important when higher currents are used because the voltage drop across the test leads may be large compared to the voltage drop across the contact.
VF测试需要提供一个已知的电流然后测量二极管上产生的电压降。
The VF test is performed by sourcing a known current and measuring the resulting voltage drop across the diode.
带有编程控制的转化速率可以控制从一种负荷装置转换到另一装置，以降低电力布线上感应电压降，或控制测试设置上的感应瞬变电流。
A programmable slew rate allows a controlled transition from one load setting to another to minimize induced voltage drops on inductive power wiring, or control induced transients on a test device.
