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.
Table 5–19 Configuration for an analog output
Step Description Register(s) Value
1 Deactivate the current measure-
ment, otherwise the output may
generate false values.
5707, 5708 0 (Int32)
2 Set the Mode to “linear”. 4359, 4360 2 (Int32)
3 Set the Output to “oxygen”. 4363, 4364 1 (Int32)
4 Set the Error Level to “2mA”. 4389, 4390 2 (Int32)
5 Set the Low Level to “10.00”. 4377, 4378 10.00 (Float)
6 Set the High Level to “110.00”. 4381, 4382 110.00 (Float)
The oxygen value does not have to be set. This is done
automatically when setting the sensor type.
Table 5–20 1-Point calibration of a OP-9 sensor
Step Description Register(s) Value
1 Read the current measurement
values.
4899 to 4908 Refer to
Table 5–21.
2 Check to confirm there are no
errors, especially error bits 1, 2, 4,
5 and 6. Refer to Table 5–10. Pro-
ceed only when there are no errors
present.
3 Set the calibration values cal0 and
T0.
