Maximum Measurement Value
Maximum Measurement Value
NOTE The maximum measurement value is not the specifications but the reference data.
The maximum measurement value depends on the settings of the current
measurement range, the QSCV measurement voltage, and the integration time. See
Figures 4-2 to 4-4. Each figure shows the characteristics of the capacitance value vs.
the QSCV measurement voltage by the integration time setting. Each line in the
graph specifies the maximum measurement value for each integration time setting.
The graph data is applied to the measurement when the QSCV integration time is set
to the same value as the LEAK integration time.
