COE Parameter Description

COE parameters 0x8000~0x8090 are used for parameter settings of the thermocouple module. The parameters marked with yellow “ ” are reserved parameters and cannot be configured. Note: when n takes values from 0 to 9, it corresponds to channels 1 to 10 respectively, where channels 9 and 10 are cold junction compensation channels.
