So...How do I keep from blowing up my scope.

Post by george graves »

Hey guys. I picked up a new Rogold 50 MHz scope. Really like it - I'm really glad I spent the money.

Rigol DS1052E 50MHz Digital Oscilloscope

But, I've only used a scope in a few electronics classes in college. Every time it was using a battery or a bench top power supply. My question is:

- Is there anything I need to do to make sure I don't blow it up? Of course I'll be stay away from the high voltage of the coil, but I would like to be able to watch the switches earth terminal to see the coil fire. And injectors, and all the good stuff - ect.

What do I need to watch out for? If I fry this scope I won't have the funds to buy another one for several months.

Thanks!

The inputs on that scope is 1M ohm, pretty high input resistance, should be enough by itself to save you from blowing the unit most of the time. I do not know what the max voltage range on the scope is, it is probably about -40v to +40v, if you are looking at higher/lower voltage than that, then use the 10x setting to the probe to drop the signal to 10% before the signal reaches the scope. With 10x, you should be able to measure something around +/- 400v.

I have the same scope, quite a gem for the price.
