How To Measure Automatically - Owon SDS-E Series Quick Manual

1. Press the "Trigger Menu" button and call out the trigger menu. With the
operations of the menu selection buttons, the trigger setting can be changed.
2. Use the "TRIG LEVEL" knob to change the trigger level setting.
By rotating the "TRIG LEVEL" knob, the trigger indicator in the screen will
move up and down. With the movement of the trigger indicator, it can be
observed that the trigger level value displayed in the screen changes accordingly.
PS: Turning the TRIG LEVEL knob can change trigger level value and it is also
the hotkey to set trigger level back to 0.
3. Press the button "50%" to set the trigger level as the vertical mid point values of
the amplitude of the trigger signal.
4. Press the "Force" button to force a trigger signal, which is mainly applied to the
"Normal" and "Single" trigger modes.

How to Measure Automatically

Press the Measure button to display the menu for the settings of the Automatic
Measurements. At most 8 types of measurements could be displayed on the bottom left
of the screen.
The oscilloscopes provide 24 parameters for auto measurement, including Period, Freq,
Mean, PK-PK, RMS, Max, Min, Vtop, Vbase, Vamp, OverShoot, PreShoot, Rise Time,
Fall Time, +D width, -D width, +Duty, -Duty, Delay A→B , Delay A→B , Cycle
RMS, Cursor RMS, Duty cycle, and Phase.
The measured values can be detected on each channel simultaneously. Only if the
waveform channel is in the ON state, the measurement can be performed. The automatic
measurement cannot be performed in the following situation: 1) On the saved waveform.
2) On the mathematical waveform. 3) On the XY format. 4) On the Scan format.
E.g. Measure the period, the frequency of the CH1 and the mean, the peak-to-peak
