DIS4 probe for distributorless ignition systems with high tension wires
- 25 USD
DIS4 - is a capacitive type sensor designed for diagnosing DIS, distributorless systems (up to 4 cylinders are diagnosed simultaneously). The sensor is directly mounted on high tension wires and gives the ability to measure secondary voltage parameters, accessing ignition spark capability and identifying problems related to high-voltage wires, plugs, caps and coils.
- blue sensors for negative-going signals – 1 pc
- red sensors for positive-going signals – 1 pc
The sensor clips around the spark plug wires and detects the pulse created when a spark is produced in a contactless way, converting it to a waveform for display. The sensor’s case is rubberized, which makes a fragile sensor element damage-proof and high voltage protected. A soft cable with a high density braided copper shield to minimize noise pickup so you can get high accuracy of the measured signal.
The sensors are color-coded, since the diagnostic technique involves determining the polarity of high-voltage wires and connecting the appropriate sensors to them, red or blue.
