The Hantek HT308 extension cord is a simple accessory that is suitable for accurate secondary ignition measurements on Coil-on-Plug (COP) ignition systems when there is no or only limited access to the ignition leads. The HT308 is capable of measuring high voltages on these circuits in combination with a capacitive secondary ignition pickup such as the Hantek HT25 ignition probe.
The extension cord is very easy to use: simply fit it between the coil pack and the plugs, place the Hantek HT25 ignition probe on each lead, and your oscilloscope will show accurate ignition waveforms with the correct voltage measurements. The HT308 can be used on all oscilloscopes that are capable of displaying ignition patterns. One such oscilloscope is the Hantek 2D82 Auto automotive oscilloscope.
