Hantek HT25 Auto Ignition Probe

The HT25 Auto-Probe is a tyoe of inductive capacitance probe, intended for use with an oscilloscope. Its purpose is to help diagnose engine ignition problems. It works by displaying a waveform corresponding to voltage against time for a cylinder parade.

The capacitive sensor is designed to measure the voltage that is generated in the secondary forces the ignition coil (transformer). The sensor adjusts the signal for optimal display on the screen of the ignition process of a digital oscilloscope. Tongs are sturdy and durable construction, earth clamp jaw is large enough to easily fit in the engine compartment and the overall ergonomics underscores the long cable length 2.5 m

Attenuation sensor is 1000:1, that means 1V displayed on the oscilloscope grid represents the secondary 1kV

Auto ignition probe HT-25 can be used with most oscilloscopes and motortesters from other manufacturers assuming, that oscilloscope has invert display function and attenuation setting to value 1000:1 or 10000:1.

Auto ignition probe HT-25

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.

Use the diagnosis

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.

Examples of use - Ignition systems:

  • 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.
