Compensation by resistance thermometer on the 2AI RTD
If thermocouples connected to the inputs of the 2 AI TC have the same reference
junction, compensate using a 2AI RTD.
You can selected ”RTD” or ”none” as reference junction for the two channels of the
2AI TC module. If you select ”RTD”, the same reference junction (RTD channel) is
always used for both channels.
