The paper describes a scanning switch.It is easy to increase the number of channels on condition that ensuring low thermal EMF.At the same time by setting hardware and software of the scanning switch it is also easy to switch between the bipolar method and the same-polarity method for thermocouple calibration,without requiring the user to reconnect.
