Looks like a 4224. Should be on a tag on the back or you can see the model under Help/About in the software when it is attached.

Thank You Mr. Roberts,
Yes it is a 4224 on the box. Are there any differences that you are aware of so that I may revise the Classified listing. Thank You for the heads up.

According to Picoauto, the difference is this will not have the Automotive Software CD in the box. However the Software is available for download free at their website. Hardware is excatly the same between the two.

So..why wouldn't it be a 4223 like it shows in the picture?

It will not work with the automotive software. I just noticed that it didn't say Automotive on the scope case. But I have seen them with the wrong cases on them before....

I have found that once you install the Pico Automotive Software; you simply remove the OEM.dll file and any scope model will work with the software just fine. I'm currently using the 4224 scope that's labeled oscilloscope with the Automotive Software with no problems.

You are a lucky guy. A ground loop can be fatal. Only the automotive scopes have thermal fuse protection.

Sure...short version:

Because the scope grounds are common (connected together inside the scope) you can create ground loops with your channel grounds that can pass current from one ground point to another, ground out a sensor, etc. This why any and all grounds should be placed on a common point, preferably bat neg.

Should you place one channel ground on a voltage source and another on a ground point a potentially large current will flow through the scope. Don't laugh. It happens more often than you think. The automotive scopes have resetting thermal fuses to protect the scope from damage should this occur. The test and measurement versions do not and you only make that mistake once and the special smoke comes out. Smiley
