3.2.3 Disconnection state conversion setting function (Q68TD-G-H01
only)
This disconnection state conversion setting function stores specific values into measured
temperature values when disconnection is checked.
This function can identify the disconnection detection from measured temperature values.
This function is only available for channels enable temperature conversion.
