| Adding a ruler |
|
To add a vertical ruler:
1 Move the mouse to the approximate position for top of the ruler.
2 Press and hold down the left mouse button while dragging the mouse downwards.
3 PicoScope draws a vertical ruler.
4 Move the mouse left or right to set the required position.
5 Release the left mouse button.
To add a horizontal ruler:
1 Move the mouse to the approximate position for the left-hand end of the ruler.
2 Press and hold down the left mouse button while dragging the mouse to the right.
3 PicoScope draws a horizontal ruler.
4 Move the mouse up or down to set the required position.
5 Release the left mouse button.
If there are two Y axes, pressing the left mouse button associates a horizontal ruler with the left axis, and pressing the right mouse button associates a horizontal ruler with the right Y axis. A small coloured box appears at one end of the ruler to show the axis with which it is associated. You cannot associate a ruler with the third or fourth channel of a four-channel oscilloscope.
You can add up to two cursors: if you add more cursors, each new cursor will replace the oldest one.
PicoScope will display the current positions of the cursors (labelled "x" and "o"). If the two cursors are on the same axis, PicoScope will also display the difference ("xo") between the positions of the two cursors.
