Waveform Display

The screen consists of three parts:

• Waveform Display
• System icons
• Datalogger Specific icons

Waveform Display

The waveform display provides a graphical indication of activity occurring within the displayed parameters. This feature provides a display of various waveforms simultaneously. Each waveform represents a vehicle parameter indicating measured activity in relation to time. The display is dynamically updated at the frequency of the sample interval.

To the right-hand side of the waveform is a digital read-out of that signal.

A vertical dotted line (cursor) on the screen represents the point in time displayed by the digital read-out.

This cursor may be moved by applying finger pressure to the screen in the position the cursor is required.

The system up or down icons can be used to scroll the waveform display up or down respectively to look at the other displayed waveforms.

System Icons

For a detailed description of each of the system icons, refer to the on-screen Datalogger Training Programme.
