Thaum siv lub thickness gauge los ntsuas, xyuam xim rau cov ntsiab lus hauv qab no:
(1) Thaum ntsuas, ua tib zoo saib xyuas lub taub hau sab thiab qhov ntsuas qhov ntsug.
(2) Ua kom lub siab ruaj khov thaum ntsuas, txwv tsis pub nws yuav cuam tshuam rau kev nyeem ntawv ntsuas.
(3) Thaum ua qhov kev sim, nws yuav tsum tau muab sau tseg tias cov hlau nplaum hlau nplaum thiab qhov roughness ntawm daim ntawv txheej txheem substrate yuav tsum zoo ib yam li daim ntawv xeem.
(4) Ua tib zoo saib xyuas qhov cuam tshuam ntawm curvature ntawm cov qauv ntawm qhov ntsuas thaum ntsuas. Yog li ntawd, nws yog unreliable los ntsuas rau saum npoo ntawm lub nkhaus test piece.
(5) Ua ntej ntsuas, ua tib zoo saib seb puas muaj lwm yam khoom siv hluav taws xob nyob ib puag ncig yuav ua rau muaj qhov sib nqus. Yog tias muaj, nws yuav cuam tshuam nrog lub thickness gauge ntawm lub magnetic thickness ntsuas txoj kev.
(6) Ua tib zoo saib xyuas lub thickness ntawm lub hauv paus hlau thaum ua qhov kev xeem. Yog tias nws ntau dua qhov thickness no, qhov ntsuas yuav tsis cuam tshuam los ntawm lub thickness ntawm lub hauv paus hlau.,
