Set the timebase to 2mS
Set the vertical amps to 0.5v/div.
Set the coupling to DC.
Set the vertical position of the trace in the center of the display.
Set the trigger mode to auto.
Set the trigger source to ch1.
Clip the probe on the calibration point.
Do you see a locked square wave?

No i haven't a square wave
with your setup i have this ??

That's a square wave. Set the time base a few clicks clockwise until you have about 3 full cycles on the display.
Adjust the focus to get as sharp a trace as possible.

ok thanks perry
i have this is it ok ?
this is the picture:
I surrounded two buttons, when i touch them the functions are the same is it normal ? they align the trace to horizontal...
Thanks

The top one should move the trace from side to side. It's to align the trace to the markers if you're going to use the scope to make calculations.
The bottom one should make a difference in the vertical amplitude. Leave it in the 'cal' (fully clockwise) position.

great thanks perry 🙂
i have a better picture of the scope from the owner
the website
CQ620C/620CF/640C/640CF
can you tell me please if i do a good deal for the price or ......259.5 euros
i have also a button near horizontal position call swp/var may i need to set it to cal position or not ?
for the trigger i have a button name level can you tell me if i need to set it or not ?
how can i use it to mesure a dc voltage please ?

Only you can determine if the deal was OK.
Set the swp/var to cal.
The level control will be used to make the scope trigger properly on the waveform.
You use a voltmeter for voltage. You can get a rough reading on the scope. Go to page 73 of my car audio site. It tells you how to measure the voltage on a scope.

cool Perry
I will go on your website
thanks 🙂
so if i understand i must set all button on "cal position" for a standard measurements ?

If you don't have the controls set to cal, you can't use the scope to measure time, frequency or voltage.
ok thanks Perry
So i set buttons:
- the swp/var to "cal"
- the second buttons of volts/div for CH1/CH2 to "cal" "fully clockwise"
Now i've seen your website but you don't explain what button i can push or use to do the measurement 😕
I do a test with an accu of 9V
i set the scope:
-Time/div to 1v/div
-volt/div to 1v/div
-trigger source to CH1
-Mode CH1
-button of CH1 to DC position.
-probe to x10
this is the measurements
Is it a normal result ?
with my multimeter i have 8.4 volts and on the scope ???

That's right. You have just under 10v (vertical amp set to 1v and probe set to 10x). That would require 10v to deflect one major division.
Ok so if i understand a division is a graduation mark "like a school rule" and not a square ?
if you can confirm me that please 🙂
for all measurements i only need the CH1X or i must set the time/base to XY and use CH2 to measure DC voltage ?
I try to measure the DC voltage of an 13.8 smps supply on CH1x and i have this result ????
I set time/div to 1
volts/div to 1
and dc voltage
for me the result is 7 volts not 13.8volts or 70volts because the prob is set to 10x 😕
It's confused
Can you explain me please ? 😱
Sorry for all theses stupid questions from a newbie 😱

With the scope set to 1v/div (major division) and the probe set to 10x, it takes 10v to deflect the trace 1 major division. You have approximately 1.5 major divisions of deflection so you have approximately 15v. Again, the scope is not for critical voltage measurements.
ok thanks Perry 🙂
Now i begin the pcb of my smps car audio 🙂 it's hard for me but I am persevering 🙂

You should power up the power supply you have to see what the waveforms and voltages are at various points.
Hello
Ok Thanks Perry for your help 🙂
for the moment i try to build my PCB the final circuit will have theses dimensions 10cm X 15cm because i only have this type pcb board 🙄

Hello 🙂
I've got news about my pcb supply based on blaupunkt schematics 🙂
Here is a draft not completed
It's verry difficult for me "it's my first pcb supply" 😱
The IC is difficult to draw 🙁

Yes !!! I finish this smps 🙂 😛
for my first smps do you think it's good ?
this is a view with all components but ref are missing
Thanks in advance for any comments 🙂
