Abstract

A compensation method for cold junction of temperature controlling console is used to compensate the temperature difference of cold junctions when a plurality of temperature controlling consoles are connected in series, where one temperature controlling console is master temperature controlling console and others are slave temperature controlling consoles. Each of the consoles has a serial input end, a serial output end and a master/slave communication end, where the serial output end of one slave console is connected to the serial input end of next slave console to form serial connection. The master/slave communication ends of all consoles are connected parallel. When the master temperature controlling console at end of the series sends a communication protocol data to all slave consoles, the slave consoles set their communication protocol to judge the positions thereof and then set the temperature compensation according to their position and their built-in program for cold junctions.
