You may not appreciate it at this point but your oscilloscope will be your #1 diagnostic tool right next to the DMM.
First step is to read the User Manual.
Second step is to become familiar with each control on the front panel. We will guide you with this.
thanks, I will go through theseHello,
The booklet XYZ of oscilloscopes will give you hints on how to use an oscilloscope.
I have my line in the middle with the knobs where you specified. The probe I have is switchable between x1 and x10. it is set to x1 right now.Leave the TIME/DIV control to 1ms for now.

Let us discuss the input BNC jack now.
CH1 and CH2 inputs are 1MΩ impedance with 25pF parallel capacitance. This is typical for oscilloscopes.
This means that when your input of the 'scope is connected to a circuit under test it will load your circuit with the equivalent of a 1MΩ resistor and a 25pF capacitor in parallel. This may or may not create a problem. In general we want the load impedance to be as large as possible.
That is the function of a x10 oscilloscope probe. Check your probe and see if it is x1 or x10. Some probes have a switch selectable x1 and x10 function. Let us know what you have and we will discuss this in more detail.
There is a red rotary knob on CH1 and CH2 controls.
Pull is knob out for x5 gain. Normally you will use this knob pressed in for x1 gain.
Turn the knob fully clockwise to the CAL position. These two settings are your usual settings.
Turn the VOLTS/DIV knob fully counter clockwise to 5V.
This means that your 'scope scale is now calibrated at 5V per division.
A span of four division (half the screen height) would reflect 20V input signal with a x1 probe.
Adjust the CH1 position to bring the horizontal trace to the mid-screen (scale with the fine tick marks).
thanks for explaining these, I did not understand what chop and add meant at all.Mode:
Cha1 - just channel 1
Cha2 - just channel 2
Alt - Sweeps A, then B
Chop - It does a piece of each channel alternately
Add - Adds two channels. When B is inverted A-B
ALT and CHOP depend on the frequencies involved.
