The TA398 COP and signal probe from Pico Technology is the easiest and fastest non-intrusive way to check coil-on-plug ignition coils and spark plugs.
- Find misfires fast
- Displays scope patterns of the secondary, faster than scoping the primary
- Can also be used to investigate injectors and other inductive actuators
- Flexible design allows for easier access to hard-to-reach components
- No batteries required
Like distributors, spark plug wires are starting to disappear from cars. With the new COP ignition systems the ignition coils are connected directly to the spark plugs — eliminating the need for the spark plug wires. With no high-voltage spark wires, a COP probe is required to be able to pick up the secondary ignition waveform.
Unlike the BNC TA204 COP Probe, the connecting lead is integral to the COP Probe, and a TA033 is not required.
This lead is fitted with a PicoBNC+ interface, allowing it to be recognised by the software for auto-configuration. The lead requires a PicoScope featuring the PicoBNC+ such as the 4225A or 4425A.
