These sources include thermoelectric EMFs, offsets generated by rectification of RFI (radio frequency interference), and offsets in the voltmeter input circuit.
这些误差源包括热电动势、由射频干扰(RFI)经过整流而产生的偏置量以及电压表输入电路中的偏置量。
This added voltage is mainly power line frequency and its effect on the voltmeter reading will depend upon the normal-mode rejection capability of the meter.
这个相加的电压主要为电源频率的信号，其对于电压表读数的影响决定于电压表的串模抑制能力。
One example of a multiple closure would be to route a single device output to two instruments, such as a voltmeter and a frequency counter.
复用开关的一个简单例子就是将单台设备的输出连接到2台仪器，例如一台伏特表和一台频率计数器。
