I downloaded both the datasheet and user guide for the USB-TC. When I started looking at the specs for the Type T thermocouple, there was a huge difference between the two documents (attached). Which of these manuals is correct? If it is the datasheet, are the specs between 0°C and -200°C interpolated for values other than 0° and -200°C? Same for 0° to 400°C. If the User Guide is correct, how are the temperatures above 400°C calculated? The polynomial equations for Type T only go as high as 400°C but the spec goes to 600°C. If the datasheet is correct, then how can the Type T range be -570° to 400° when absolute zero is -273.15°C (-459.67°F, 0°K, 0°R)?
