Model 6517B Electrometer Reference Manual Section 14: SCPI command reference

:IREFerence <b>
This command is used to control the amps reference.
Usage
[:SENSe[1]]:RESistance:IREFerence <b>
:IREFerence?
<b>
 ON or 1: Enable amps reference for ohms
 OFF or 0: Disable amps reference for ohms
Details
This command allows you to use an established amps reference for the resistance measurement.
When an amps reference is established, and this command is used to enable the amps reference for
ohms, the current value used to compute resistance (Iohm) is the algebraic difference between the
input current and the reference:
Iohm = Iinput - Ireference
Resistance (R) is then computed using Iohm and the V-source output (V).
R = V/Iohm
Typically, amps reference represents the leakage current in a test fixture. Thus, this command allows
you to eliminate this leakage current for the resistance calculation.
