Eeeeeps... multiple user errors ... after my first successful testdrive
I was re-wiring and cleaning up the cables. Stupid me messed up there and now I am in recovery mode having a VREF out of range indication in the rtd explorer ...
If I measure +5V between SGND and +5V on the LEM but nothing between SGND and CURRENT does that mean my LEM is broken ?? Or could anybody suggest more measuring points that could indicate other defects ?
