Q = Quick performance verification test pointsCapacitance verification testConfiguration: Capacitance (CONFigure:CAPacitance)1. Connect the calibrator to the front panel HI and LO input terminals as shown above. The cable capacitancebetween EDU34450A and calibrator must be impedance controlled with less than 100 pF of cable capacitance.For best accuracy, use only coaxial cable or shielded twisted-pair cable.2. Select the Capacitance function.3. Select each range in the order shown below. Provide the input capacitance value as indicated below.4. Compare measurement results to the appropriate test limits shown in the table.
