Capacitance Accuracy The Capacitance Accuracy test verifies the accuracy of the synthesized capacitance output at the 5500A Calibrator front panel AUX terminals. Table 3-21 shows the test points. Use the Fluke 6304C LCR Meter with PM9540/BAN output cable as shown in Figure 3-5. This cable eliminates the need for a four-wire connection. Note Make sure there are no other connections to the 5500A, especially the SCOPE BNC. Connecting any additional grounds to the 5500A can cause erroneous capacitance outputs. To overcome a noise problem, increase the meter’s signal current by increasing the voltage or frequency. 3-29
