Sesebediswa sa ho kenya mocheso sa RTD se ka arola le ho fetola letshwao la resistor ya mocheso (RTD) hore e be letshwao la DC, le sebediswang ho kganna mojaro. Tlhophiso e bohlale e a kgoneha, mme mefuta ya nnete ya khanyetso ya mocheso e ka bewa ka software ya khomphutha. E na le mosebetsi wa alamo ya ho kgaola le mosebetsi wa alamo e sa fihlelleng.
Sehlahisoa sena se hloka ho tsamaisoa ka boikemelo, 'me phepelo ea motlakase, li-terminal tsa ho kenya le ho ntša li arotsoe.
