The Test Lead Design

The test lead is specially designed for making measurements in internal combustion engines. A soft microphone cable with a high density braided copper shield to minimize noise pickup so you can get high accuracy of the measured signal. 4 mm "Banana" plugs are used as test probe connectors; BNC is a sensor - oscilloscope connector.

With the help of a standard 4 mm Banana plug you can easily connect/disconnect/change test probes. This plug is compatible with test probes from other manufacturers as well as multimeters. Socket function is marked on the housing end.

TL-mlp Test Lead pinout

The removable 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, which enables to reduce the circuit rust. The spring prevents the pin from accidental breakage.

When designing the test lead, high emphasis has been placed on a signal cables joint as this junction is damage-prone. Each of these joints includes a circuit board with the test lead’s electronic components. The board not only supports the loads, but also fixes the cable. Such solid joints prevent cable breakdown and increase its durability.

The test lead is compatible with the MT Pro scope as well as any other automotive oscilloscope. It can be connected to any analog channel.
