Math Setup
Now that the parameter setups are done, you have to set up the Trend math function.
1. Touch Math in the menu bar, then Math Setup... in the drop-down menu.
2. In the "Math" dialog, touch the Fx tab for the math trace you chose to display
the trend.
3. Touch the "Trend" tab in the setup dialog to the right of the main
setup dialog. Touch inside the Values to Trend data entry field and enter a value from 20
to 20,000, using the pop-up numeric keypad.
4. You can touch the Find Center and Height button to automatically locate the center of
the Trend waveform and to scale it to fit within the grid, without affecting zoom and
position settings. Or you can enter specific values by touching inside the Center and
Height data entry fields and typing in values, using the pop-up numeric keypad.
5. You can also touch the Enable Auto Find checkbox if you want the
instrument to continuously self-adjust Center and Height.
