| Abstract: | The paper is emphasized on the problem to the inaccuracy of temperature readout, which is caused by the improper connection to resistance probe. Analyzing inner circuit of the instrument in theory and combining with experiment, the paper put forward the optimum connection of three-line-system at long distance (not ignoring the cable resistance) and some using advice. |
