I am a beginning student should say old student in electronics another sucker purchased goldstar off ebay it was cheap so no loss if I fail.
Sorry about background info now to the problem bear with me also learning to operate the oscilloscope.
The scope powers up fine has a nice line hoz beam across the screen but unable to get any rise on vert y axis applying 9 volt bat doesn't raise the beam. Using the setting for scope I was able to find on youtube and internet.

 

I assume ou have it...
- set to DC (other settings are "ground" and AC)
- have probe cable connected to the input channel displaying on screen (probe connector should be labelled - and selector switch should be set to same
- switch on your probe should be set to 1x or 10x (not set to "REF").
- ground clip is connected to one terminal and probe tip is on other terminal.

 

Hello,

Do you have the operating manual?
If not, you can download it as a DJVU file over here:
