In this paper, a method is introduced to set up an automatic measurement system which is made of constant current source unit, voltage meter, switch matrix and computer with IEEE - 488 interface.
Taking the KEITHLEY 6517 electrostatic meter as measurement standard, using the standard metermethod, the accurate and reliable verification to the DC low current reference source could be realized.
