6.2 Examples
6.2.1 Configuration of a continuous measurement
Precondition: Sensor is connected, and sensor constants and calibration values are already set up correctly (OP-9).
The goal for this configuration is a continuous measurement with a 1-minute interval with the pressure sensor and
RTD (Pt100) are deactivated. Instead, a manual fixed value will be transmitted. Refer to Table 30.
Step Description Register(s) Value
1 Stop the measurement, if it is running. 5707, 5708 0 (Int32)
2 Set pressure mode to “Manual”. 5705 0 (Boolean)
3 Set manual pressure to “1006.23”. 3147, 3148 1006.23 (Float)
4 Set temperature mode to “Manual”. 5611 0 (Boolean)
5 Set manual temperature to “20.56”. 2409, 2410 20.56 (Float)
6 Set the interval rate to 1 min. (“60” seconds). 3499, 3500 60 (Int32)
7
Activate the interval mode and start the continuous measurement
immediately.
5707, 5708
5 (Int32 translates to
00000101 binary)
8
Read measurement control register. If bit 1 is deleted, see step 9. If bit
1 is set or the display has timed out, repeat step 7 until value shows ‘0’
(max. 400 ms after which time-out detection should be implemented).
5707, 5708 /
9 Read out the last measurement. 4895 to 4908 Refer to Table 31.
10 Read out the oxygen unit. 2089, 2090
1073741824 (Int32 translates
to 0x40000000 hex, meaning
ppm gas)

6.2.2 Configuration of an analog output
• Precondition: Sensor is connected, and sensor constants and calibration values are already set up correctly (OP-
9). 4-20mA Output is already in a calibrated state.
The goal for this configuration is to set up the analog output 1 for a linear oxygen value output between 10 and 110
ppm gas, with an error level of 2mA.
Step Description Register(s) Value
1 Deactivate the current measurement, 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.
