1·Plessey describes EPIC as essentially a very sensitive, contactless digital voltmeter capable of measuring millivolt changes in electric fields.
Plessey将EPIC电位集成电路描述成一个本质上非常敏感的非接触式数字电压表,它可以测量到电场中的毫伏变化。
2·Another consideration when measuring voltages from high resistance sources is the input bias current of the voltmeter.
在测量高电阻源时要考虑的另一个问题是电压表的输入偏置电流。
3·The ohmmeter USES an internal current source and electrometer voltmeter to make the measurement.
欧姆计使用内部的电流源和静电计电压表来进行测量。
4·If using a separate current source and voltmeter to make low resistance measurements, each instrument must be checked for non-ohmic contacts.
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。
5·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。
