3.3.1 Graph functions
The graphic functions Zoom and Cursor enable detailed analyses of the graphs.
<Menu>
Zoom:
When the magnifying glass shown in the display rests on a white background, it has not yet
been zoomed.
When the magnifying glass is placed over a green background, the graph is zoomed.
You can vary the graph size from 25% to 100% using the zoom softkeys. This doubles or
halves the resolution. When concurrently using the cursor, you can precisely localise the
reflection on the measured line.
Cursor:
When the Cursor function is started, a red cursor line appears in the middle of the graph.
Use the left and right cursor keys to move the cursor to any position on the graph to mea-
sure it. Briefly pressing the cursor key causes the cursor to jump to a new position in the
graph. When the cursor key is held down, the steps the cursor covers in the graph become
progressively larger.
The Zoom function and the Cursor function can also be combined. For example, you can
determine a certain value using the cursor more easily when you have previously zoomed
in on a specific area. However, the starting position of the cursor can vary.
Range-X: Sets the displayed measuring range. Every press of the cursor key halves or
doubles the displayed range.
Opens graph functions.
<Cursor>
You can toggle the cursor on and off as needed using the Cursor softkey after
activating it in the menu.
