Basic Operation 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. Note: All selected menus are highlighted in orange.
