Characterization accuracy specifications shown for Model 5156.
For optimum calibration accuracy, test equipment specifications should be at least
four times better than corresponding Model 6430 specifications. The Model 5156
Electrometer Calibration Standard, however, does not meet these requirements. As a
result, Model 6430 1pA-100nA and 2GΩ-200GΩ range accuracy specifications will
be relative to Model 5156 characterization accuracy.
