Matching the composition of the wires between the cryostat and the voltmeter and keeping all dissimilar metal junction pairs at the same temperature allows making very low voltage measurements with good accuracy.

适当的选配低温容器和电压表之间连接导线的材料成分，并且保持所有不同金属材料结点对都处在相同的温度之下，就能够以很好的准确度来进行非常低电压的测量。

Measurements of sources at cryogenic temperatures pose special problems since the connections between the sample in the cryostat and the voltmeter are often made of metals with lower thermal conductivity than copper, such as iron, which introduces dissimilar metals into the circuit.

测量低温环境下的源时可能会出现一些特殊的问题，因为连接低温条件下的被测样品和电压表时常常要使用一些导热系数比铜低的金属，例如铁等。这样就会在电路中引入不同种类的金属材料。

If the current cannot be reduced, use a narrow current pulse and a fast responding voltmeter.

如果不能降低电流的话，使用窄的电流脉冲和快速响应的电压表。
