When T.C .input, T.C. cold-junction temperature compensation will be needed according to its temperature measuring principle (Please refer relative information).There are three kinds of compensation modes: NULL(no compensation, used for measure), doid (Inner auto temperature component),Cu50(external RTD Cu50 compensation).”diod” compensation can measure the terminal temperature on the bear of the meter and compensate for T.C. cold –junction compensation. But because of the error of measuring component, meter itself heating and other heat source near meter, it usually leads to big deviation of the compensation by “diod” compensation, whose error can be up to 2-4℃ at worst. Please adopts “Cu50” compensation if require higher measuring accuracy: Please connect a external box and put Cu50Cu resistance purchased in your side and the T.C. cold-junction together and keep them far away from kinds of heating sources, If so, the inconsistency of the measuring caused by compensation is less than 0.5℃。If change external Cu resistance to accurate resistance, it can also achieve compensation function of constant temperature bath. For example, please connect 55Ω resistance externally with relative temperature 23.4℃ by Cu50 index table; please put T.C. cold –junction .in constant temperature bath in 23.4℃ to get more accurate compensation, which is higher than Cu resistance compensation. The connection of the two ways of cold-junction compensation as follows：The equipment uses RS485 communication connection acquisition card to achieve real-time recording, monitoring and query
