Auto ignition probe is a kind of inductive capacitance sensor, it must match with an oscilloscope.
Close to use, can be used to test a spark ignition secondary overlapping wave, overlapping wave parameters, thus achieved the detection, the diagnosis engine ignition position, make each cylinder ignition voltage changing with time directly from the oscilloscope display.
The loot line has three ends, a joint meet oscilloscope for BNC use, a clip for use, a clip grounding to pick high-voltage gleaned clip with. Loot clincher over is a attenuator, used for loot high-pressure attenuation for low pressure, thus protecting oscilloscope not electrify impact.
When used please note:
(1) Test clips shall not directly clip in spark plug, should be caught in the connection of the spark plugs of insulation wire, in order to prevent the breakdown and causing a shock.
(2) To distance other high-voltage at least 2 inches apart, lest produce interference.
(3) HT25 leading line length 2.5 meters, the decay of up to 10,000:1.
(4) Always use the ground clip
(5)Do not let the metal portion of the pickup contact a ground
Connect the HT25 to the automotive oscilloscope before connecting to the vehicle
Connect the ground clip to a good ground on the vehicle
Connect to vehicle
