Are there any guidelines concerning the ctrlX IO thermocouple card (XI361002 - 2-channel analog input for thermocouples) and using grounded thermocouples vs. ungrounded thermocouples?

Hello, in the data sheet we have a hint related this
"Use galvanically isolated sensors to avoid falsified measured values." - galvanically isolated is equal to ungrounded. Grounded thermocouples currently not supported.
