The following figure shows the default parameters for the QTsweep82 user module.

The Q/T sweep in Equilibrium test (QTsweep) description (on page 6-14) acquires 20 quasistatic
capacitance readings. After the graph for quasistatic capacitance and leakage current versus time is
plotted, the optimum delay time for equilibrium can be determined.
For details on quasistatic measurements, see QTsweep (on page 6-13). For details on C-t
measurements, see C-t sweep (on page 6-18).
The Range values are shown in the following table.
