I have a problem with my USB TC08: sometimes, at some or all sensors, it gives the wrong temperature (t-type sensor), typical 7 degrees lower than the actual temperature. This phenomenom occurs quite randomly: it can happen once and that be alright for days and then stick there no matter how many times you restart the computer.
I use the TC08 in combination with another usb datalogger (dataq) and a balance connected to the serial port. I use a similar combination on another PC, only with a serial TC08s, and I have never seen the problem there.
Has anyone seen similar behaviour and above all, who knows how to fix it?
