3-35. 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.
