TL-mix4 Mixer Test Lead

The mixer test lead can be connected to electromagnetic injectors, primary circuit or control signal of individual ignition coils. It allows you to record a signal from up to four sources at the same time, using only one analog input of the oscilloscope.

The Test Lead Design

Items Included

• mixer test lead - 1 pc
• replacement flexible pin lead probe - 4 pcs

Test leads are color-coded so never again will you waste your time wondering which lead is which.

Using 4 test leads allows you to make measurements on 4 ignition coils or injectors at a time, and therefore you can analyze the signals directly from all the cylinders of the engine. The pulses of ignition coil control as well as the injector control pulses from different cylinders never occur at the same time, which allows summing signals from all the test leads in order to get one signal at the output with a series of sequential pulses identifying the ignition system as a whole.

NB! The test lead doesn’t have a separate grounding terminal; therefore, an additional grounding wire of the oscilloscope is required.

The mixer test lead is specially designed for making measurements in internal combustion engines and allows you to work comfortably with in-line, V-shaped and opposing engines. 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 replacement leads are made of a flexible PVC cable. A flexible lead pin is ideal for connecting an oscilloscope to automotive connectors as well as other recessed areas. A thin pin and a handy holder allow connecting to virtually any connector without damaging the circuit and wiring insulation. The spring prevents the pin from accidental breakage.

The test lead is compatible with any automotive oscilloscope.
