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 MI074 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 MI074 comes with a shielded 1.8 m (6 foot) lead. It is suitable for use with conventional ignition systems and most HEI and DIS systems. Our library of Automotive Waveforms contains example waveforms captured using a PicoScope automotive oscilloscope and the MI074. Although ideal for use with a PicoScope automotive oscilloscope, the MI074 pickup can also be used with most other makes of oscilloscope provided they have a waveform invert option.
You should generally only purchase bare modules as a replacement when you already own a kit.

Bare scope modules do not come with an Autonerdz Training & Support subscription.
