Repair attempt mPulse Handheld LIBS Metal Analyzer

Reference report Schrott-Nasz GmbH

The mPulse metal analyzer used by the company no longer functioned. Unfortunately, the manufacturing company didnt´t exist anymore. Successors no longer offer to repair the mPulse and Schrott Nasz‘s own repair attempts failed.

SIGMA was the only company that dared to attempt a repair on request.

One of the causes of the device failure was the uncontrolled switching off of the device by disconnecting the power supply unit due to a missing battery (defective) and the occasional destruction of data structures on the internal flash, which is common for many devices. The control module comes from Toradex. An Nvidia Tegra T20 ARM SoC is installed.
A lot of experience and know-how, fun in troubleshooting, measurements, tools available from Toradex and a little luck the data structures could be saved and restoredand the application could be restarted again. The display, which was also defective, was replaced.

Conclusion

The final success is still awaited, as apparently other parts of the hardware and/or software do not work together as they were supposed to.
We are continuing our search and will report in an update if we are successful.
