To change the vertical scale knob’s coarse/fine adjustment
setting
1 Push the channel’s vertical scale knob (or press the channel key and
then the Fine softkey in the Channel Menu) to toggle between fine and
coarse adjustment of the vertical scale.
When Fine adjustment is selected, you can change the channel’s vertical
sensitivity in smaller increments. The channel sensitivity remains fully
calibrated when Fine is on.
The vertical scale value is displayed in the status line at the top of the
display.
When Fine is turned off, turning the volts/division knob changes the
channel sensitivity in a 1- 2- 5 step sequence.
To invert a waveform
1 Press the desired channel key.
2 In the Channel Menu, press the Invert softkey to invert the selected
channel.
When Invert is selected, the voltage values of the displayed waveform
are inverted.
Invert affects how a channel is displayed, but does not affect triggering.
If the oscilloscope is set to trigger on a rising edge, it remains set to
trigger on a same edge (triggers at the same point on the waveform)
after the channel is inverted.
Inverting a channel will also change the result of any function selected
in the Waveform Math Menu or any measurement.
