To set up channel coupling 
 
To use Channel 1 as an example, input a square wave signal with DC shift. 
Press CH1ėCouplingėDC to set “DC” coupling. Both the AC component and the 
DC component of the input signal will pass. 
 
The waveform is displayed as Figure 2-3:

Press CH1ėCouplingėAC, to set “AC” coupling. It will pass AC component of the 
input signal with frequency higher than 5 Hz and restraint DC component of the input 
signal. 
The waveform is displayed as Figure 2-4:
