Useless Scope for Tire Testing

As a result of my tests, I determined that this scope is unreliable in detecting tire issues, providing inaccurate readings that lead to faulty repairs. The only pro is that it has two channels, but that's not enough to outweigh the cons. The interface is difficult to navigate, and the instructions are unclear. It's a waste of money and time.

Pros
  • Accurately diagnoses automotive electrical problems with its two-channel scope.
Cons
  • Requires significant expertise to use effectively and interpret results.

Example: when you do a relative compression test, once you stop cranking, the waveform disappears forever and you can no longer view it. Someone has to start the engine. as you watch the pattern develop, press and hold it, then save it to one of four locations. This saved pattern cannot…

Pros
  • Diagrams with the pin numbers and wire colors for both the PCM and the component connector are visible on the screen.
Cons
  • Expensive
