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。
Its output signal can be displayed by digital voltmeter, signal conditioner or dynamic strain amplifier with recorder.
其输出信号可用数字电压表，信号调节器，或动态应变仪接示波器记录。
Measuring apparatus can use general digital voltmeter with appropriate accuracy, but generating standard dynamic strain signal is a problem which hasn't been well solved.
测量仪器可用适当精度的通用数字电压表，而标准动态应变的产生则是尚未很好解决的问题。
