Reset Sensor
Con
fi
guration: >
Use this function during initial startup of a new system, and whenever a new sensor is added
to the system. It enables the 8250 to scan the sensor input terminals and determine the type
and speci
fi
c serial numbers of the sensors connected to the sensor input.
Technical Note
If you see this error
The most likely cause is
Remedy
Too Much Error
Check Sensor
A new sensor was connected to the 8250
but the "Sensor Reset Con
fi
guration" has
not been executed.
Perform the sensor con
fi
guration.

IMPORTANT TECHNICAL ADVICE. DO THIS FIRST!
Before proceeding with the calibration, press the UP key twice, then press the RIGHT key to restore the function of the con
fi
guration of
the sensor (sensor con
fi
guration RESET). This procedure is part of the sensor 8250 and provides for many calibration functions.
