CtSweep test description
As shown in C-t sweep (on page 6-18), the CtSweep UTM uses the CTsweep82 user module to
make C-t measurements. Refer to CtSweep82 user module (on page 6-32) for definitions of the input
parameters.
If using the parameters shown in C-t sweep (on page 6-18), the 590 performs 100 capacitance
measurements using a 100 ms sample time between reading samples. The time interval between
reading samples is determined by the set sample time and the selected reading rate.

The graph below shows for this test plots capacitance versus time.
