    Hi all,

    Just an update.  I uploaded ‘d_simple_logger’ to see what is coming directly from the sensor.  It seems that the sensor itself is producing the -9992 values, rather than it being created somehow by the Mayfly.

    I have contacted METER and they are looking into it.  I suspect the sensor is faulty.
