Cov hlau no yog siv rau kev tsim cov qauv tsis kam, cov hlau precisioncov qhov txhab resistors, potentiometers, shunts thiab lwm yam 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.
