Vim li cas kev ntsuas dej noo hauv cov ntawv thiab cov khoom ntim khoom tseem ceeb?
Daim ntawv thiab nws cov khoom muaj feem xyuam yog siv dav hauv kev lag luam ntim khoom thiab muaj kev puas tsuaj thaum muaj dej noo ntau dhau ntawm cov khoom no. Cov dej noo kuj tseem ua lub luag haujlwm tseem ceeb hauv kev ntsuas cov khoom siv, uas tsis muaj kev ntseeg siab. Kev tswj cov dej noo tam sim no hauv cov khoom yuav ua rau koj tsim cov khoom zoo rau cov neeg siv khoom. Yog li ntawd, nws yog ib qho tseem ceeb heev rau koj kom tswj tau cov dej noo hauv cov khoom no los ntawm kev sim zoo.
Lub ntsuas dej ntawm tes ntsuas ntsuas yog cov cuab yeej ntsuas tau zoo uas tso cai rau koj los txheeb xyuas cov ntsiab lus noo noo nyob hauv daim ntawv thiab cov khoom ntim. Thaum twg koj xaiv cov cuab yeej kuaj sim no, koj yuav tsum khaws qee yam hauv siab thaum xaiv cov khoom no. Lwm yam tseem ceeb suav nrog cov xwm txheej huab cua raug, rov ua dua ntawm kev tshuaj xyuas, thiab lawv qhov zoo.
Tam sim no, cia peb tham txog cov hom muaj thaum nias lub khawm MODE hauv hygrometer.
Thaum nias lub MODE khawm hauv lub ntsuas dej noo, ntau hom kev siv tau
1. Tshawb xyuas qhov nruab nrab ntawm kev nyeem ntawv
Yog tias tus neeg siv nias lub pob "Nias ntsuas qhov tseem ceeb" thaum tso tawm cov ntaub ntawv lossis tom qab tso tawm qhov ntsuas kev nyeem ntawv, qhov kev nyeem ntawv nruab nrab, tag nrho cov ntawv nyeem, qhov siab tshaj plaws thiab qis tshaj plaws yuav tshwm sim. (Txhua hom ntawv tuaj yeem khaws txog 100 nyeem)
2. Teem kev txwv rau hom ntawv xaiv (UPPER thiab POWER)
Cov neeg siv tuaj yeem siv tus yuam sij "Enter" txhawm rau nkag mus rau kev txwv, thiab cov yuam sij "UP" thiab "Sab laug" yog siv los teeb tsa kev txwv. Tom qab teeb tsa cov kev txwv tsim nyog, tus yuam sij "Enter" yog siv los khaws cov kev txwv.
Cov ntaub ntawv ntshiab (rho tawm cov ntawv nyeem khaws cia rau hom ntawv xaiv)
Cov dej noo ntsuas los ntawm qhov ntsuas tuaj yeem khaws cia hauv lub cim xeeb ntawm chav tsev, thiab tag nrho ntawm 100 kev nyeem ntawv tuaj yeem khaws cia hauv lub cim xeeb ntawm txhua hom ntawv. Txhawm rau tshem tawm cov ntawv nyeem, nias lub pob "Enter" thiab hais kom tus neeg siv nias lub "Enter" khawm dua kom tshem tawm cov ntaub ntawv rau cov ntawv xaiv hauv lub cim xeeb.
3. Xaiv hom
Hauv hom no, koj tuaj yeem xaiv hom ntawv. Nias tus yuam sij "Enter" txhawm rau saib cov ntawv xaiv, siv tus yuam sij "UP" los xaiv hom ntawv, thiab nias lub pob "Enter" kom paub meej tias qhov kev xaiv. Lub ntsuas dej digital feem ntau muab peb hom ntawv xaiv.
a) Ntawv (4.7-18.2 feem pua)
b) Tus neeg siv calibration (8-100 feem pua)
c) Ntim cov ntawv pov tseg (6-40 feem pua)
Cov no yog cov qauv sib txawv muaj nyob rau hauv no handheld noo noo meter.
