Transcript What is a scope?

What is a scope?
• Essential tool for automotive diagnostic and
fault finding.
• Ideal for viewing and testing most automotive
sensors and circuits.
• Captures and stores signals from sensors,
components and actuators.
• Displays and expands spikes and complex
signals.
What can it do?
The kit can be used to measure and test virtually all electrical and
electronic components:
• Ignition (Primary &
Secondary)
• Injectors & fuel pumps
• Starter & charging currents
• ABS sensors. Crank & cam
sensors
• Relative compression tests
• Glow plugs/timer relays
• Lambda, airflow, knock &
MAP sensors
Why use a scope?
• 2 main diagnostic techniques - ECU Fault codes and scopes.
Both have advantages, but used together are very powerful.
Scopes enable the actual signals to be viewed
• Scopes speed up diagnostics, especially where there’s no fault
code, or it is wrong or misleading. A real Time-Saver !
• A scope can confirm fault code diagnosis, before expensive
parts are swapped out. They may just need cleaning!
• Reduced Manufacturer Warranty Costs - due to elimination of
unnecessary replacement of non-faulty parts. Connections and
wiring faults can easily be pin pointed
• Easy saving of data for analysis, and comparison with stored
benchmark traces. Waveforms can be transmitted easily by
email, for remote diagnosis.
ADC-212/3
The Pico ADC-212/3 PC oscilloscope/meter is our recommended
product for automotive diagnostic and fault finding.

How do I use it?
In the PicoScope software, the Automotive menu contains a list of
the different sensors and circuits that can be tested with the
Diagnostic kit. When the subject of interest has been selected, the
software will automatically do a number of things:
• Load a reference waveform into PicoScope
• Load a web page. This shows how to connect the scope, gives
advice on what the waveform should look like and gives general
technical information
• Load the required settings, removing the need to spend time on
setting up the PicoScope
