Description

Unit to study the function of various analog and digital sensors.

The device is equipped with original sensors for monitoring the differential pressure of a DPF, as well as for detecting the position of the accelerator pedal and for monitoring the gear neutral position and the brake pedal position. Additionally, the knocking sensor 73903 can be connected.

The SENT signals according SAE J2716 can be presented and evaluated directly with the Automotive diagnosis tester software 739589*.

The device has a high-speed CAN bus interface, to which the signals of integrated sensors are output.
Via the CAN Bus Adapter USB 739581USB or CAN bus multi-adapter 773961, the measured signals can be evaluated.

The device is designed with a full color print. For the supply voltage T 30, the ignition T 15, CAN High, CAN Low and the ground signal connections from left to right are for easy connection of other devices available .

*software version 1.18 and newer
