6.1.8 Compensation temperature
This value is used for compensation of the oxygen calculation.

2411 2 Float: Temperature value in °C Yes
Table 17. Definition of register 2411
6.1.9 Measurement interval
The oxygen measurement interval can be set between 1 and 359999. Setting the interval to “0” will lead to Modbus
error response with code 3.
The measurement values may be read any time but are updated only with the interval set in these registers. Hence,
polling the measurement values in a higher rate than the measurement interval should be omitted as it leads to
unnecessary traffic on the bus.

6.1.10 Device ID RS-485, RS-232 and Ethernet
Sets the device ID used in the Modbus RTU communication. If a value over 32 is set, the device will reset its ID to 1,
which may lead to communication errors. If no ID is set, or the ID is not known, set the ID via broadcast (ID=0).
