high-resistance voltmeter

基本解釋

High resistance measurements using the constant-current method may be made using either an electrometer voltmeter and current source or just an electrometer ohmmeter.
采用恒流法，可以使用靜電計(jì)電壓表和電流源或者只使用靜電計(jì)歐姆計(jì)來(lái)測(cè)量高電阻。
The input resistance of an electrometer voltmeter is extremely high, typically greater than 100T. (1014ω). Furthermore, the input offset current is less than 3fA (3x10-15 A).
靜電計(jì)的輸入電阻非常高，其典型值可達(dá)100Tω（1014ω），而且輸入偏置電流小于3fA（3x10-15 A）。
