To adjust the math waveform scale and offset
1.
Make sure the scale and position knobs above and below the
[Math]
key are selected for the
math waveform. If the arrow to the left of the
[Math]
key is not illuminated, press the key.
2.
Use the scale and position knobs above and below the
[Math]
key to resize and reposition
the math waveform.
Math Scale and Offset are Set Automatically
Any time the currently displayed math function definition is changed, the function is
automatically scaled for optimum vertical scale and offset. If you manually set scale
and offset for a function, select a new function, then select the original function,
the original function will be automatically rescaled.
