AideTek PX25A New Professional Secondary Ignition Pickup Probe X10000 for PICO Scope
used with Oscilloscope, brand new with 1 yr USA warranty
The Secondary Ignition Probe allows the oscilloscope function to measure the Kilovolts value of ignition systems with Distributorless system (DIS) or conventional ones.
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.
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 Auto-probe is a kind of inductive capacitance-probe, which should be used with the oscilloscope to test the waveform as the "primary parade waveform", "secondary parade waveform" To accomplish the purpose of inspecting the ignition-system of the engine. By this method, you could see the variation of the ignition-system voltage via the time on the screen of the oscilloscope directly.
To ensure the proper operation, please note:
<1> The test-clip should be connected to the isolative wire of ignition plug instead of ignition plug itself to prevent the fire of electrical shock.
<2> At least 2inchs away from other high-voltage wires to avoid the interference.
Cable length: 100 inch or 2.50m
This 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.
It comes with a shielded 2.5m (100 inch) lead. It is suitable for use with conventional ignition systems and most HEI and DIS systems.
