When using an oscilloscope to verify the operation of a CE (Common Emitter) amplifier, it's important to adjust the VOLTS/DIV setting when going from the amplifier input to the amplifier output because the purpose of an amplifier is to increase the voltage level of the signal. The input signal will be at a lower voltage compared to the amplified output signal, necessitating an adjustment in the oscilloscope's VOLTS/DIV setting to accurately display the increased output signal amplitude. Adjusting the TIME/DIV setting is not specifically required for verifying amplifier operation as it relates to the time scale, not the amplitude. Connecting the external trigger is not a necessity for basic operation verification; it's more about stabilizing the display for repetitive signals, which doesn't directly relate to the act of verifying amplifier operation.
