Find your channel in the automation explorer where you set up your virtual channels. Select properties for the channel configured for temperature. You may specify the CJC Source select built in by using the drop down box.
In the devices where your SCXI Chassis is listed, you will need to make sure you have the correct terminal block attached to the module. For the ll02 you indicated in your question you have the 1303 or the 1300, check your terminal block and make sure you have the correct one selected. This is important. For changing the resistors I recommend you read the documentation for the device to make sure you change the correct channels. Also you will find this documentation better written and pictures help illustrate the instructions. If your thermocouple is not grounded and you do have the 1303 terminal block, the factory shipped configuration will work. But it is probably best for you to set up the block as suggested for thermocouples. The 10 Mohms (10x-1-106) resistor is recommended. As I mentioned the documentation supplied with these products are a bettor source of information for some of the questions you are asking.
