Cov hlau no yog siv rau kev tsim cov qauv tsis kam, cov hlau xaim hluav taws xob uas muaj zog, cov potentiometers,kev hloov pauvthiab lwm yam khoom siv hluav taws xob
thiab cov khoom siv hluav taws xob. Cov hlau tooj liab-Manganese-Nickel no muaj lub zog hluav taws xob thermal tsawg heev (emf) piv rau tooj liab, uas
ua rau nws zoo tagnrho rau kev siv hauv cov hluav taws xob circuits, tshwj xeeb tshaj yog DC, qhov twg lub thermal emf spurious yuav ua rau malfunctioning ntawm hluav taws xob
cov khoom siv. Cov khoom siv uas siv cov hlau no feem ntau ua haujlwm ntawm chav tsev kub; yog li ntawd nws cov coefficient kub qis
ntawm kev tiv thaiv yog tswj tau ntau yam ntawm 15 txog 35ºC.

Cov Ntawv Thov Manganin:

1; Nws yog siv rau kev ua hlau qhov txhab precision tsis kam

2; Cov thawv tiv thaiv

3; Shunts rau cov cuab yeej ntsuas hluav taws xob

Cov ntawv ci thiab hlau manganin siv rau hauv kev tsim cov resistors, tshwj xeeb tshaj yog ammeter shunts, vim nws qhov kub thiab txias coefficient ntawm tus nqi tsis kam thiab kev ruaj khov ntev. Ntau cov Manganin resistors tau ua haujlwm raws li tus qauv kev cai lij choj rau ohm hauv Tebchaws Meskas txij li xyoo 1901 txog 1990. Hlau manganin kuj tseem siv ua tus neeg coj hluav taws xob hauv cov kab ke cryogenic, txo qis kev hloov pauv cua sov ntawm cov ntsiab lus uas xav tau kev sib txuas hluav taws xob.

Manganin kuj tseem siv rau hauv cov ntsuas rau kev kawm txog cov nthwv dej siab (xws li cov uas tsim los ntawm kev tawg ntawm cov khoom tawg) vim tias nws muaj kev ntxhov siab tsawg.
