Due to the high voltages involved in secondary ignition systems, it is not possible to make measurements by direct connection. Attempting to make a direct connection will almost certainly damage the measuring instrument.

The 733-TA397 is a capacitive pickup that simply connects around the insulation of an ignition circuit component such as a plug wire. This avoids the need for direct connection.

The 733-TA397 comes with a shielded 6 foot (1.8 m) lead and features a BNC connector for scope input. It is suitable for use with conventional ignition systems and most HEI and DIS systems.

This lead is fitted with a PicoBNC+ interface allowing it to be recognized and auto-configured by PicoScope oscilloscopes, that also feature PicoBNC+ inputs like the 4225A or 4425A.
