Use the cursors (see page 89) to select the graph and data range to which you want
to apply the Timing wizard.
•
Time resolution
The time resolution depends on the sampling rate. Use the table below to select a
rate that meets your needs.
•
Use the Trigger
For fast events and high sampling rates use the Trigger tool (see page 102) to initiate
the data logging.

Crop Tool

The Crop tool enables you to trim the edges of a data set. Use it to remove unwanted
data or to apply manual curve fitting to a desired range of data points.
The time scale of the trimmed data is shifted so that it will start at
If you want the automatic curve fit equation to start at
before any type of curve fitting
After applying the crop tool, the trimmed data set replaces the original set on the
graph display and a new icon is added to the Data Map under cropped data.

1. To trim all data up to a point

1. Position a cursor (see page 89) on the data point
2. Click on the Graph menu, then click Crop.

2. To trim all data outside a selected range

1. Use the cursors to select the range you want to keep
2. Click on the Graph menu, then click Crop.

Capture Tool

The Capture tool enables you to capture and record specific data points from the
TriLink stream of data, like taking snapshots of the dynamic process. For example,
you can design a light refraction experiment that will record the angle of the refracted
