1. When the timebase is 500ms, the scope enters scan mode automaticly. Please view the user manual.
When it stops, you can change the timebase from 500ms to 1s to zoom out the waveform.
2. There are more waves outside the right side of the screen. You can narrow the waveform(change the timebase from 500ms to 1s after it stop) to see the right wave. If you want to acquire more data, please use bigger timebase.
3. A little deviation from the oscilloscope is normal.
Why do you use the 10V/div to measure a 1V or smaller signal？You can choose 200mV/div to measure.
The DC Gain Accuracy of this scope is ±3% * full range.
Please use small gear as much as possible so that the results will be more accurate.
If you want to use high precision equipment, please choose high precision equipment.
