(1) Txhawm rau txav qhov kawg ntawm cov thermocouple los ntawm qhov siab - qhov kub thiab txias mus rau qhov chaw uas muaj qhov kub thiab txias ambient.
(2) Yuav kom txuag tau tus nqi tseem ceeb ntawm cov khoom kim heev thiab tsis tshua muaj hlau siv hauv kev tsim cov thermocouples.
(3) Ua kom yooj yim installation thiab xaim.
(4) Hloov cov thermocouples nrog cov kab tuab tuab dua li cov xaim hluav taws xob thiab cov khoom siv hluav taws xob ntau dua yuav txo tau qhov kev tiv thaiv ntawm thermocouple Circuit Court, yooj yim rau kev ntsuas thiab tsis siv neeg tswj.
