Maximize the application by touching the shortcut icon located on the
lower-right of the screen.
A sequence of calibration screens are shown when the Touch-Screen
Calibration button is touched. These screens instruct you to touch a series
of displayed crosses in order to improve precision and accuracy when using
your touch screen.
The Service button is a section of the application reserved for qualified
Teledyne LeCroy personnel. When touched, an access code pop-up is
shown enabling Teledyne LeCroy technicians access to various service
dialogs inside the oscilloscope software.
PLEASE NOTE THE FOLLOWING:

Use a stylus for this procedure. Using your finger for the calibration
prompts provides insufficient accuracy for the procedure.

The calibration procedure times out after ten seconds pass and no cross is
touched.

Avoid parallax errors by placing your line of sight directly in front of each
cross before touching it.
