Auto Range
- Continuously automatic, the oscilloscope continuously adjusts the vertical scale, horizontal time
base and trigger level in a real-time manner according to the magnitude and frequency of signal. It is defaulted
as off and needs to be opened in the menu. This function is mutually exclusive with “Auto Set”.
Open the main menu and tap “Auto” to open the auto range menu for the corresponding settings. When the
oscilloscope auto range function is turned on, the oscilloscope will automatically set various parameters,
including: vertical scale, horizontal time base, trigger level, etc. When the signal is connected, these parameters
will automatically change, and the signal does not need to be operated again after the change. The oscilloscope
will automatically recognize and make the appropriate changes.
⚫
Auto range: Turn the auto range function on or off
⚫
Vertical scale: Turn on the vertical scale automatic adjustment function;
⚫
Horizontal time base: Turn on the horizontal time base automatic adjustment function;
⚫
Trigger level: Turns on the auto-adjust trigger level function.

Auto Range is usually more useful than Auto Set under the following situations:
1)
It can analyze signals subject to dynamic changes.
