Qhov teeb meem koj tau hais txog qhov qhib Circuit Court nyob rau hauv lub platinum tiv thaiv tus pas ntsuas kub yog qhov ua rau muaj kev txhawj xeeb txog qhov txuas ntxiv thiab qhov tseeb ntawm qhov ntsuas kub hauv qhov chaw tsim khoom. Kuv nkag siab tag nrho cov kev ntxhov siab uas tshwm sim nrog kev cuam tshuam tam sim hauv kev ntsuas qhov kub thiab txias-tshwj xeeb tshaj yog thaum lub sijhawm txheej txheem tseem ceeb, qhov twg txawm tias ib qho thib ob ntawm qhov txawv txav tuaj yeem ua rau poob loj.
Thaum qhib Circuit Court tshwm sim nyob rau hauv lub platinum tiv thaiv tus pas ntsuas kub, nws tsis tuaj yeem rov qab los ntawm nws tus kheej; nws yuav tsum tau muaj kev cuam tshuam los ntawm phau ntawv - kho lossis hloov pauv - txhawm rau rov ua haujlwm. Ib qho qhib Circuit Court qhia txog kev cuam tshuam tag nrho ntawm qhov ntsuas qhov ntsuas kub; lub cuab yeej yuav tso saib "∞" lossis ua kom muaj ntau tshaj - tswb. Lub sijhawm no, lub cuab yeej tau poob nws qhov kub thiab txias -sensing peev xwm nkaus xwb, thiab lub tswv yim ntawm "lub sijhawm rov qab" tsuas yog siv tsis tau.
I. Vim li cas lub ntsuas kub platinum tsis tuaj yeem rov qab tau txais tom qab qhib Circuit Court
Lub cev zoo: Platinum tiv thaiv tus pas ntsuas kub cia siab rau cov xov hlau platinum zoo heev (feem ntau Φ0.03-0.07 hli) kom paub qhov kub thiab txias. Ib qho qhib Circuit Court tseem ceeb txhais tau hais tias cov hlau platinum tau tawg, tsim ib lub voj qhib.
Tsis Muaj Tus Kheej-Kev Muaj Peev Xwm Kho Mob:** Tsis zoo li qee yam khoom siv hluav taws xob, cov khoom siv hlau tsis muaj tus kheej- kho cov khoom; ib qho chaw so yuav tsis rov txuas dua vim qhov kub thiab txias hloov los yog lub sijhawm dhau mus.
Kev Ceeb Toom: Kev sim yuam kom cov khoom siv tam sim no "rov qab" nws yuav ua rau muaj cua sov hauv zos, uas yuav ua rau muaj kev puas tsuaj ntxiv lossis tsim kev nyab xeeb.
II. Kev tuav cov txheej txheem thiab cov sij hawm rov qab rau qhib Circuits

Hloov nrog Cov Khoom Tshiab |
Break point nyob rau hauv lub sensing ntsiab; yam tsis tuaj yeem disassembled. |
1-4 teev (nrog rau kev kaw, tshem tawm / nruab, thiab calibration) |
Pom zoo rau cov khoom uas tsis yog- kho tau, xws li armored probes lossis ceramic-encapsulated element. |

Arc Vuam Kho |
Mica- hom pob txha pob txha nyob qhov twg qhov chaw tawg tuaj yeem nyob. |
2-6 teev (xws li vuam, rwb thaiv tsev, thiab pov thawj) |
Yuav tsum tau ua los ntawm cov kws tshaj lij; lub cuab yeej yuav tsum xeem dhau kev kuaj xyuas tom qab vuam ua ntej siv. |

External Lead Breakage nkaus xwb |
Kev tawg tshwm sim nyob rau hauv cov kab hluav taws xob ntawm lub thawv davhlau ya nyob twg thiab cable. |

Nws tuaj yeem kho sai sai uas siv cov - kub solder, yog tias muaj kev sib npaug sib npaug ntawm peb lub taub hau yog ua kom ntseeg tau. |
Kev Ceeb Toom Tseem Ceeb: Txawm hais tias yuav siv txoj kev kho li cas, cov cuab yeej yuav tsum tau kuaj xyuas qhov ntsuas ntawm 0℃thiab 100℃tom qab kho kom ntseeg tau tias nws cov nqi tsis kam ua raws li IEC 60751 tus qauv (piv txwv li, Chav A: ± 0.15℃). Tsis ua li ntawd yuav ua rau qhov ntsuas kub tsis raug.
