Calibration
Recommended calibration equipment
Table 19-1 lists the recommended equipment for the calibration procedures. You can use
alternate equipment as long that equipment has speci
fi
cations at least as good as those listed in
the table.
NOTE
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 2G
Ω
-200G
Ω
range accuracy specifications will
be relative to Model 5156 characterization accuracy.
