The Test Lead Design

TL-dif differential test lead drawing

The differential test lead is specially designed for making measurements in internal combustion engines. A soft microphone cable with a dense braided shield is used as a cord. 4 mm "Banana" plugs are used as test lead connectors; BNC is a test lead - oscillograph 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.

If needed, the mini hook lead probe can be replaced by a flexible pin or an alligator clip.

The removable probes are made of a flexible PVC cable. A plunger test hook is ideal for connecting an oscillograph to automotive wires, connectors, PCB pads and other recessed areas.

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 motor tester as well as any other oscillograph. It can be connected to any analog channel.
