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