To set the DL850 ScopeCorder in Roll Mode, turn the Time/Div knob until it is set to 100msec/Div or longer.
If the Time/Div is set to 1Hr/Div or longer, waveform scrolling can be difficult to observe in real-time. This is due to the fact the waveform appears compressed on the time axis.
To observe the waveform in real-time, turn the Zoom window ON, and move the Zoom Position all the way to the right. Set the Main Ratio to 50% and adjust the MAG knob accordingly.
Yokogawa data acquisition systems give you the most flexibility and power to measure, display, store, and even actuate any number of physical or electrical phenomena.
