All sensor information must be valid before the configuration can be written to the probe.

Normalizing Sensors

Normalization is the setting of the range over which the sensor is effective. For example, soil moisture

sensors have a range bounded by the 2 extremes, air and water. The normalization process is necessary

to adjust for any variances that may occur during the production of the sensor.

Changing the Calibration Information

The sensor coefficients cell is used to store A, B and C coefficients. The coefficients are entered in A, B

then C order, separated by semicolons.

Setting the SDI-12 Address

The address of the probe should be in the range “0” to “9”, “A” to “Z” and “a” to “z”.
