Ground Coupling
Used to display a zero-volt waveform. Internally, the channel input is connected with a zero-volt
reference level.
Fine Resolution
In the fine resolution setting, the vertical scale readout displays the actual VOLTS setting. The
vertical scale changes only after you adjust the VOLTS control and set to coarse.
Remove Waveform Display
To remove a waveform from the screen, first push the menu button to display the vertical menu,
then push again to remove the waveform. A channel waveform which is unnecessary to be
displayed can be used as a trigger source or for math operations.
3. VOLTS
Control the oscilloscope to magnify or attenuate the source signal of the channel waveform. The
vertical size of the display on the screen will change (increase or decrease) to the ground level.
Also you may use the key F3 to switch between coarse and fine.
4. MATH MENU: Display the waveform math operations. See the table below for details.
The MATH menu contains source options for all math operations.
