泄漏电流是由测量电路和附近的电压源之间的寄生电阻通路产生的。
Leakage currents are generated by stray resistance paths between the measurement circuit and nearby voltage sources.
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.
在测量仪器上附加电流和电压源功能，为各种低电平测量应用提供了额外的灵活性。
Adding current and voltage sourcing capabilities to a measuring instrument provides an extra degree of versatility for many low level measurement applications.
