3-26. Verifying Capacitance

Verify that the 5520A performance is within the limits in Table 3-28. Use the PM 6304C
RCL Meter directly for capacitance values up to and including 109.000 F. Above
109.000 F, you must use a timed charge up routine with a constant current source in
order to achieve the required test uncertainty ratio.
To verify capacitance greater than 109.000 F, see the section titled "200 F to 110 mF
Capacitance Verification" found later in this chapter.
