Hi the SE000 is a k type thermocouple used to measure temperature. The TC-08 can measure temperature and voltage, if you have the serial TC08 it measures +/-60mV if you have a USB TC08 it can measure +/-70mV. To measure voltage you don't use the thermocouples. What are you trying to measure?
I am going to use the TC-08 as a voltmeter. there is parameter Full scale input: Â±70 mV. Well what does it mean for me? Would voltage across the input terminals higher then 70mV destroy the device? Or would it withstand 2x70mV=0.14V? Which terminal shall I connect the ground of my tested system?
