Signal rulers
The signal rulers are to help you measure signal levels with respect to ground, or
signal differences, on a scope view .
In the scope view above, the two coloured squares to the left of the vertical axis
are the ruler drag-handles. You can drag these from the top-left corner to the
positions you want to measure on the waveform. The two horizontal dashed lines are
the signal rulers.
Ruler legend
The table at the top of the view is the ruler legend. In this example, the table shows
that ruler 1 is at 807 millivolts, ruler 2 is at -811.0 millivolts and the difference
between them is -1.618 volts. If you prefer to see the difference as a positive value,
swap the positions of the two rulers by dragging them.
Ruler tooltip
If you move the mouse pointer over one of the rulers, PicoScope displays a tooltip
with the ruler number and the signal level of the ruler. You can see an example of this
in the picture above.
