( 1) Thermocouple and thermal resistance should be installed vertically in a horizontal or vertical piping as far as possible, when installation should protect casing, to facilitate maintenance and replacement.

　( 2) Should be in the same environment temperature of the cold junction of the thermocouple, should use the same model compensating lead wires, and the positive and negative to connect to.

　( 3) Temperature measurement of the pipe, the length of the element should be in the center of the pipe line ( The protection tube insertion depth should be the half of pipe diameter) 。

　( 4) Moving coil temperature table when installation, the size of the hole to appropriate, installation to the beauty is generous.

　( 5) Using high resistance to high temperature or high temperature compensation cable.

　( 6) According to the different choice of different temperature measuring element. General measure temperature greater than 100 ℃, should choose thermocouple, less than 100 ℃ when choosing thermal resistance.

　( 7) Connection to a reasonable and beautiful, whose hands pointing to correct.
