  1. One USB-TC can be mounted 8 thermocouples. I had mounted 8 T-thermocouple on the MC USB-TC. We know that when we start to use the T-thermocouples and USB-TC to measure the temperature, we have to calibrate the system(thermocouples + USB-TC) firstly. During the calibration, we use calibration bath to calibrate thermocouple, which filled with water. Question 1: Can I calibrate the 8 thermocouples in one time? And the thermocouples could be put in water directly or thermocouples shall be put in a bag which avoid run current between the thermocouples in water(that can have impact on the measurement). Question 2: I put the 8 thermocouples and one standard PT100 in water. The calibration bath was set at 31℃ and the PT100 showed the temperature was 31.1℃. However the 8 channels of USB-TC showed different values. Showed as attached photos, compare the value measured by PT100 and thermocouples, the max different was about 0.52℃. It was quite big. Why some thermocouples looks quite different with correct value?
