Zoom – Pressing this button changes the menu at the bottom of the screen (Figure
5-34) allowing the user to change the time window (Zoom Time, the horizontal axis) and
the amplitude (Zoom Amplitude, the vertical axis).
For the PRO receiver, the zoom amplitude shows the range of amplitudes shown (i.e., a
Zoom Amplitude of 60 means it shows from -60 mV to +60 mV).
For the Ultra receiver, the zoom amplitude shows a percentage of the amplitude window
(i.e., if you have an amplitude window of -50 mV to +50 mV, and the Zoom Amplitude is
set to 50, it means the image is zoomed in to 50%, so it will display -25 mV to 25 mV)
Press the + and – buttons to change these axis values. Press Back when complete.
