Hi everyone, I don't have much practice with the oscilloscope so I'm not sure if it's malfunctioning or I'm missing something, I'd appreciate some help. I have a rigol DS1054z and I'm trying to see how a capacitor charges overtime by putting it in series with a resistor. I set the oscilloscope to normal mode and set the appropriate scales. But when I press the run button, the status says run and the screen shows the normal background squares but I don't see the yellow voltage line as I see when using the auto mode. At first I thought it was a triggering problem so I pressed the force button and hear a sound but still I don't see the voltage line. I know it's measuring because I was just pushing buttons trying to make it work when suddenly I saw the voltage line (I set a time base of 20 sec) of what was previously measured so I know my setup is fine. This has happened 2 or 3 times, I've been at it for a while... For some reason it's not displaying the voltage line not sure if that's normal and I'm missing something really obvious or its malfunctioning, any ideas? |

What's your voltage (vertical) scale set to, and what voltage are you using in your circuit under test? Also, is the vertical position set so the trace is on the screen? |
| d4n13l:
The voltage value per grid is 2V with a horizontal time base of 20sec (the charging of the capacitor takes 10sec) and I'm running the circuit on 5V. As for you last question, I just made sure the screen is centered before starting to measure... As I mentioned, I know its working because apparently for not reason the trace suddenly appears and its centered, when this happens I see the progress of the trace just fine. This also shows that the measuring is happening its just not displayed on the screen |

On long time bases the scope accumulates the data first and then displays it. It looks for a trigger condition. |
| d4n13l:
But it should display what has accumulated when you push the force button, doesn't it? When I do it the screen stays the same with no trace |
