Hi all as some of you may remember I have an Oscilloscope its a tek 2205 20Mhz.
I was trying to learn how to test the discharge time of a capacitor but unlike on a digital scope I cant keep the trace on screen to see when I pressed the button to charge to when I releases it to watch the capacitor discharge.
Do you have the oscilloscope in the NORM trigger mode not the AUTOMATIC Mode, with DC trigger coupling and minus slope? In the NORM mode you can adjust the trigger level so that it will only trigger at start of the discharge.
Nope I had it set to AUTO I will give what you say a go when I next get free in me workshop (problems with having kids and a better half I suppose hahahahaha).
