The oscilloscope can be thought of as a plotting machine. What is plotted on the a axis? What is plotted on the y axis? If you try to look at a 6 volt signal with the "volts/div" dial set on 0.2 you don't see anything. Why not? Should you turn the dial to 2 volts/div or to 0.02 volts/div to find the signal?

Answer: The oscilloscope is not a plotting machine.

Explanation: The Oscilloscope is not a plotting machine is a device which is use to measure the frequency, period, peak to peak Voltage Vpp or any signal. That is alternating.

So, if you're such you wired your circuit whose output signal you want to measure very well and all connections and settings are done accurately, then you can reduce the volt/div below 0.2. You not seeing any signal at 0.2v/div shows that the amplitude of the signal coming into the Oscilloscope is not up to that.
