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. |
Auto ignition probe HT-25 HT -25 are designed to measure high voltage the output of the ignition coils respectively of the secondary winding or secondary or power output ( for high-voltage diode) . capacitive sensor can be be used to capture high voltage waveforms, both conventional distributor ignition systems and on systems without distributor (DIS ) - the fully electronic ignition systems . For the diagnosis of the secondary coil on plug systems (EFS / COP ) is necessary use extension adapter coil on plug.
Given the very high voltage (up to 40kV ) that for secondary circuit typically not possible perform measurements directly connecting the output of the coil, as is the case with measurement of primary. Trying to such measurement could seriously endanger health technology and certainly would lead to the destruction of oscilloscope and computer. to measure Therefore, secondary use capacity and inductive sensor. involvement pliers is simple. First of all involved ground clamp pliers the motor housing , then clipped with pliers Spark cable , or the extension adapter, connector clamp connects the BNC oscilloscope input , start the engine and measure can begin. Pliers features used to measure the ignition on one cylinder , for a test to secondary four-cylinder engine , it is necessary 4 used pliers and possibly 4connection adapters.
- conventional spark systems (with distributor)
- CIC (Coil in Cap) as GM HEI, Toyota, Honda, Nippondenso etc.
- DIS (no distributor) fully electronic ignition. With the extension, also EFS / COP
Control Program HANTEK 3064 / A and 1008C are pre-measurement for very precise diagnosis of the secondary. In the preset measurement is integrated into the formula to calculate the values spark voltage (needle) voltage discharge at spark, burning time and duration inductive.
