CVU - all terminal parameters

When you select All Parameters, the Configure pane displays all available parameters for the test
that is selected in the project tree.
Parameter descriptions are provided in the following sections.
Presoak
Type a presoak voltage of −30 V to +30 V.
Start
The voltage source level at which the sweep starts.
Stop
The voltage source level at which the sweep stops.
Step (voltage sweep)
The voltage size of each step of the sweep. The source level changes in equal steps of this size from
the start level to the stop level. A measurement is made at each source step (including the start and
stop levels).
Clarius never steps the force voltage beyond the value specified by the stop parameter, even if you
specify a step value that is larger than the stop value.
Use a step value that does not result in a fractional number of data points. If the data point is
fractional, the step value is forced to a value that results in a whole number of data points. To
calculate the data points:

Description
The cable length that was used to generate connection compensation data.
Make sure this cable length is the same as the Cable Length setting in the
Tools > CVU Connection Compensation dialog box. Refer to
compensation (on page 4-10) for additional information.
Selects the terminal to use to source AC drive voltage.
The measure range determines the full-scale measurement span that is
applied to the signal.
Selects the terminal to use to source DC drive voltage.
Allows you offset the voltage by up to ±30 V on one terminal. For example,
this allows you to output voltage from 0 V to 60 V instead of −30 V to +30 V.
The Capacitance Range Estimator automatically calculates the maximum
capacitance value based on the parameter settings in the Advanced settings
dialog box.
