Is there a older datasheet for the one that goes up to 400V? Are the specifications different for the ones that are discontinued with the higher voltage ranges?

We have this DT9874-8TC8RTD32V unit. According to the Users Manual on these units it has a ±10V and ±60V range. The unit that we have has a ±10V, ±100V and ±400V ranges. We are using the QuickDaq software. I can't find anything on these units that state that you can purchase higher voltage options.

Could you use the forecast function in excel to get the tolerance values for each temperature range?

What is the Accuracy formula for the thermocouple for the USB-2408-2AO? 1% of reading + 1°C? If I was to measure -100°C what would my tolerance be for type J thermocouple?
