When machines have issues, it can be difficult to understand the root cause of failures. For example, the failure of a single component could be caused by problems elsewhere in the system. The first step in troubleshooting is understanding what is happening and documenting it. The HYDAC HMG 4000 is a hand-held measurement and data acquisition device. It is capable of capturing data from sensors from hydraulic and pneumatic systems in both mobile and industrial settings. The HMG 4000 can capture real-time data for instantaneous viewing and record inputs on a vehicle’s pressure, temperature or valve positioning. This allows a technician to see what is driving the failure rather than the result of the failure. For instance, the technician can use the “trigger” function and set the device to record when pressure levels exceed an allowable threshold.
