1、The secondary ignition probe allows the oscilloscope function to measure the kilovolts value of ignition systems with Distributorless system (DIS) or conventional ones. 2、This is a capacitive pickup that simply connects around the insulation of an ignition circuit component such as a plug wire. 3、The Secondary ignition probe obtains the signal using a capacitive clip and a conditioning circuit in order to deliver a readable waveform to the oscilloscope. 4、It comes with a shielded 2.5m lead. 5、Suitable for use with conventional ignition systems and most HEI and DIS systems.
