This information is sent until
temperature is over range.
This error is set when the
mechanical tolerances of the
airgap parameter are out of range.
This information is sent until power
supply turns off.
This error occurs when a magnetic
cell is temporary or completely
out of order.
This error is sent at each
concerned frame.
To get the best performances,
a self-calibration is required.
This information is available until
power supply turns off.
This warning occurs when the
self-calibration is not ended
correctly. The factory settings
are restored.
This information is available until
power supply turns off.
This warning occurs when at the
power on the sensor has detected
an excessive displacement during
the power off. This warning and
the multi-turns counter are reset at
the next power on.
This warning occurs when the
sensor has performed an internal
correction error.
This warning is sent at each
