As the core unit for displaying and diagnosing machine information, it is used to read key data such as engine speed, water temperature, hydraulic oil temperature, and fault codes in real time, and can set parameters and debug functions through buttons.

This product is a handheld portable monitor with a sturdy dark gray engineering plastic shell and a metal handle integrated on the top for easy carrying and temporary installation. The front is equipped with a square monochrome LCD display screen, with four orange function buttons (up/down/back/confirm) arranged below for browsing menus and operations. Its interface is usually a standard CAN bus diagnostic interface, which is connected to the excavator main controller (ECU) through a wiring harness. The working voltage is DC 24V, and the protection level can reach IP54, which can adapt to dusty and vibrating environments on construction sites. The core functions include data display, fault diagnosis, parameter calibration, and hour meter recording.

Check if the power supply voltage is normal (24V ± 10%); 3. Try testing on other machines of the same model to determine whether it is a malfunction of the monitor itself or a problem with the entire vehicle ECU.
