6.2.3 1-Point calibration of an OP-9 sensor
• Precondition: Sensor is connected and put in a low oxygen environment. Sensor constants are already set
correctly (OP-9).
The goal for this example is to calibrate the oxygen sensor.
Step Description Register(s) Value
1 Read the current measurement values. 4899 to 4908 Refer to Table 34.
2
Check to confirm there are no errors, especially error bits 1, 2, 4, 5, and 6. Refer
to Table 8. Proceed only when there are no errors present.
3 Set the calibration values cal0 and T0. 5521 to 5524 1st Float: 66.32
2nd Float: 21.98
