A range accuracy
1.
Connect the voltage calibrator and Model 5156 Electrometer Calibration Standard
to the Model 6485 INPUT jack, as shown in
. Initially, make connec-
tions to the 1G
Ω
resistor in the calibration standard.
2.
Set the Model 6485 to the 2nA range.
3.
With zero check enabled, zero correct the instrument then disable zero check.
4.
Set the calibrator voltage to 0.0000V and make sure the output is turned on.
5.
Enable the Model 6485 REL mode. Leave REL enabled for the remainder of the
test.
