I prefer to think of channels 3 and 4 as external trigger inputs

with full waveform display... because that is what they really are.
The channel 3 and 4 volts/div for the 2445 can be anything you want as long as you
want 0.5 volts/div or 0.1 volts/div. It is selected by a pair of push buttons, one
for each channel, between the channel 3 and 4 vertical position controls.

Just adjured 2445 scope and trying to get familiar with the controls.
Not having much luck asking Mrs Google or reading text only ( no links /
reference ) manuals.
So - any owner of 2445 can tell me where / how to select vertical "Volts/Div"
setting for CH 3 and CH 4?
I can read the calibrator on CH3 OK , just cannot figure out how to set the
vertical setting for it.
