Lx-90 inductive probe
The Lx-90 inductive probe is designed to capture secondary voltage waveforms from Coil-On-Plug (COP) and DIS ignition coils mounted directly above the spark plugs.
The probe attaches directly to the ignition coil and measures secondary voltage parameters by inductively coupling to the coil’s magnetic field. This non-intrusive method allows an oscilloscope to display accurate secondary voltage waveforms without requiring a direct electrical connection to the ignition system.
This probe is equipped with a PIN2 connector and is designed to work with the USB Autoscope IV device.
The Lx-90 inductive probe is designed to capture secondary voltage waveforms from Coil-On-Plug (COP) and DIS ignition coils mounted directly above the spark plugs.
Lx-90 probe equipped with the PIN2 connector can only be used together with USB Autoscope IV, USB Autoscope Lite or DIS Adapter.
Lx-90 probe converts the inductive signal caused by the high voltage circuit of the ignition coil into a voltage pulse that is then displayed on the oscilloscope screen.
Due to the variety of ignition coils with different designs, it should be noted that the Lx-90 probe cannot determine the exact voltage at which the ignition spark occurs, but it can be used for comparative analysis between different cylinders to determine which cylinder is not working properly.
The length of the Lx-90 inductive probe cable is 2.0 m.
Precautions before use:
Keep wires and adapters away from moving and rotating parts.
Keep wires and adapters away from the exhaust manifold.
