10.4 Advanced diagnostics on the MLG-2
The supplied SOPAS ET software contains advanced diagnostics options. These options
allow you to further isolate the problem if the error situation is unclear or if there are
availability issues. You can find detailed information:
•
In the Status field (in the bottom left of the main screen)
•
In the system boundaries display (minimum detectable object for the current
configuration, minimum presence time, reproducibility, response time)
