Calibration Registers
O set Calibration
O set (zero) calibration is an arithmatic positive or negative correction to the sensor reading and is the only
type of sensor calibration available on climate/environmental sensors. To perform a sensor o set calibration,
write the correct sensor value to the o set calibration regsiter (consider the integer scaling noted.)
Span Calibration
Span, or slope calibration, corrects the slop of the sensor reading at a second point, away from the zero cali-
bration. Operations performed using the span register are:
-pH 4.01 or 10.0 calibration
-Conductivity, ORP or DO calibration to solution standard
