What is the voltage burden specification of an electrometer or picoammeter?

Question :

What is the voltage burden specification of an electrometer or picoammeter?

Answer :

An ideal ammeter will have zero internal resistance, however, a real ammeter will have a finite resistance. This resistance creates a voltage drop called the voltage burden. For feedback ammeters, the voltage burden is usually 1 mV or less at full scale.
