Instructions
1. Connect your Pico diagnostic PC Oscilloscope to your computer, switch on, and run the
PicoScope Automotive software that was supplied on the CD-ROM with your scope.
2. Open the Automotive menu, then select
Ignition, Coil-on-Plug, Secondary.
3. If you have a purpose-built grounded
COP Probe cable (Pico part number
TA033), connect it to the scope’s
Channel A input, and connect the COP
Probe to the other end of the cable.
Connect the cable’s ground clip to a
reliable ground point on the engine.
4. If you don’t have a special COP Probe
cable, you can make your own using the
standard parts in your Pico Automotive
Oscilloscope Kit. Use two BNC-to-4mm-
plug test leads and a large crocodile (or dolphin) clip. Connect the two red 4 mm
plugs together, and then connect the two black 4 mm plugs together. Connect the
pair of black 4 mm plugs to the black dolphin clip and attach the clip to the engine
block. Use the BNC plugs on the other ends of the two leads to connect the COP Probe
to the oscilloscope.
5. Hold the COP Probe by the handle and rest the metal tip against the plastic casing of
the coil pack. Don’t let it touch any metal part of the engine.
6. With the engine running, an ignition pattern should appear on the computer screen.
If you want to keep the pattern on the screen,
click the red “stop sign” button at the bottom of
the PicoScope window to freeze the display.
