Essential Oscilloscope Diagnostics

One of the big differences between technicians who diagnose complex faults and those that don’t is simple; those that do, use a scope.

The oscilloscope opens up a whole new way of diagnosing faults that stops you guessing at what’s wrong because now, using a scope, you can actually see what’s going wrong.

If you want to improve your fix rate and diagnose difficult jobs more quickly, including no-code and intermittent faults, then this is the course for you.

We can cater for most oscilloscopes and have recently trained technicians with Pico, Bosch, Snap-on, Interro, Sealey, Hantek and Texa oscilloscopes.

More Detailed Information

Oscilloscope Diagnostics will really open your eyes to the amazing diagnostic information which is available from the system under test. Especially when you consider that the scope is just as easy to connect as the multimeter, but it can give a million times more information.

This course will completely demystify using the oscilloscope.

This course will teach you how and where to connect the oscilloscope. It will take you through the golden rules of setting the scope up correctly for the component you want to test.  It will take you through triggering, recording waveforms, setting up for intermittent faults and much more besides.

If you have a scope, you’re welcome to bring it along to the course and use it on the day to do the practical tasks. This will get you started on your very own comparative waveform collection too.

During the course you will cover

  • Where, why and how to use a scope.
  • Connections and settings.
  • Scope set-up golden rules.
  • Recording and reviewing captures.
  • Using and setting triggers.
  • Taking and interpreting component waveforms.
  • Current draw, motor function and relative compression testing.
  • Current ramping (low range) fuel pumps, injectors, ignitions, solenoids.
  • Multiple channel relationship testing.
  • Taking, saving and retrieving waveforms.
  • Comparative waveform analysis & waveform overlays.
  • Intermittent and no-code diagnostics.
