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 µF. Above
109.000 µF, 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 µF, see the section titled “200 µF to 110 mF
Capacitance Verification” found later in this chapter.
