非欧姆接触可能发生在由氧化膜形成的低压电路或其它非线性连接中。

Nonohmic contacts may occur in a low voltage circuit as a result of oxide films or other non-linear connections.

为了降低电压表的非欧姆接触所产生的误差，采用屏蔽和适当的接地措施来降低交流干扰。

To reduce error due to voltmeter non-ohmic contacts, use shielding and appropriate grounding to reduce ac pickup.

如果使用分离的电流源和电压表来进行低电阻测量，则必须检查每台仪器的非欧姆接触情况。

If using a separate current source and voltmeter to make low resistance measurements, each instrument must be checked for non-ohmic contacts.
