Table 15.1 Automatic setting 
Automatic setting function checks all channel signals and displays corresponding 
waveforms. Automatic setting determines the trigger source based on the following 
criteria. 
⚫  If multiple channels input signals, choose the low frequency signal channel as the 
trigger source. 
⚫  If no signal is found, choose the lowest-numbered channel displayed as the trigger 
source. 
⚫  If no signal is found and no channel is displayed, the oscilloscope will display the 
CH1 channel and take it as the trigger source. 
When the automatic setting function is used and the oscilloscope determines that the 
signal resembles a sine wave, the oscilloscope will display the following options:
