Hey Jim,
NI Phone Support hours are from 8 AM - 6 PM Central Standard Time from Monday to Friday.
One way to see if you are measuring a correct voltage from your TC's is to use a DMM and see what raw voltage you are seeing across the TC. Then, looking at your MAX configuration, check the Signal Input Range and make sure the scaling works for your particular TC. The 1303 has a built-in CJC so that can be left on that selection.
The temperature range is going to select the range your DAQ card and SCXI card uses when passing through a signal. The 1102 has programmable gain, and the DAQ card can have either ±10V or ±100mV ranges. Both of these are specified in their respective user manuals.
Most of the online Getting Started guides give good information regarding initial configurations, but when something goes astray in the measurement you have to try and narrow down progressively which piece of hardware is receiving a bad signal. This can either be from the 6259, the 1001, the 1102, the 1303, or the thermocouple.
If you can confirm another module makes accurate measurements (1126 modules, or other 1102) then we can pinpoint that specific 1102/1303 combination as the issue. If none of the new hardware measures correctly then we have either an 1001 issue or the 6259 is not correctly measuring.
Let me know if there is anything else I can help you with, thank you.
