4. Oscilloscope is set as DC coupling with AUTO Triggering. A warning message is
displayed when trying to change these settings.
5. The oscilloscope will turn off Autoscale if user is trying to adjust vertical position,
voltage division, trigger level or time scale for CH1 or CH2. To back to Autoscale,
Press AUTOSET.
