图2 - 24示出静电计或皮安计的过载保护电路，其中包括一个电阻器和两个二极管(1n3595)。
Figure 2-24 shows a protection circuit for an electrometer ammeter or picoammeter, consisting of a resistor and two diodes (1n3595).
由于静电计、安培计或皮安计的输入端压降小于1mV，这两个二极管不会导通。
Since the voltage burden of the electrometer ammeter or picoammeter is less than 1mV, the diodes won't conduct.
