Yuav ua li cas calibration txheej txheem rau portable yaj oxygen meter?
Lub dilute oxygen meter yog ib qho khoom siv los ntsuas cov pa oxygen hauv dej. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog tias cov pa oxygen txo qis los ntawm kev ua haujlwm electrode los ntawm diaphragm los tsim kom muaj qhov sib txawv tam sim no proportional rau oxygen concentration. Los ntawm kev ntsuas qhov tam sim no, qhov concentration ntawm cov pa oxygen yaj hauv dej tuaj yeem tau txais.
Cov txheej txheem ua haujlwm calibration ntawm portable yaj oxygen meter yog raws li hauv qab no:
1. Saib seb cov zaj duab xis ntawm lub hau electrode puas puas. Yog tias nws puas lawm, hloov lub hau electrode qub, ntxiv electrolyte rau lub hau electrode tshiab, hloov nws ntawm electrode, thiab qhuav cov electrode.
2. Nyhav 5.00g ntawm anhydrous sodium sulfite khoom, dissolve nws nyob rau hauv distilled dej, thiab npaj ib tug 100mL tov, uas yog ib tug 5 feem pua zero calibration tov.
3. Nias lub khawm pib, qhib lub hwj chim, qhuav cov electrodes, thiab ua tib zoo nqus cov dej noo ntawm zaj duab xis.
4. Muab cov pa oxygen electrode yaj rau hauv 5 feem pua sodium sulfite tov. Thaum lub ntsuas ntsuas nyob rau hauv lub xeev ntsuas, nias lub "Mode/Measurement", thiab lub ntsuas yuav nkag mus rau lub hom xaiv lub xeev.
5. Nias lub "▲/mg．L-1}/ feem pua" tus yuam sij los yog tus yuam sij "▼/Storage" xaiv "ZERO" (lub kaum sab xis sab laug ntawm cov zaub), nias tus yuam sij "OK/Print" , thiab qhov ntsuas nkag mus rau xoom oxygen calibration muaj nuj nqi xeev. Tom qab kev nyeem ntawv ruaj khov, nias qhov "OK/Print" tus yuam sij, qhov ntsuas yuav tso tawm "0.00mg/L", thiab lub ntsuas yuav cia li tawm ntawm lub xeev "ZERO" tom qab kwv yees li 5. vib nas this.
6. Tshem tawm cov electrode thiab qhuav nws, muab tso rau ntawm lub platform, nias "▲/mg．L-1/ feem pua" tus yuam sij lossis "▼/storage" tus yuam sij kom xaiv "FULL" (lub kaum sab laug ntawm cov zaub), qhov ntsuas nkag mus rau tag nrho Oxygen calibration muaj nuj nqi raws li txoj cai, nias lub "OK/Print" tus yuam sij. Tom qab kev nyeem ntawv ruaj khov, nias lub pob "OK/Print", qhov ntsuas yuav pom cov txiaj ntsig ntawm cov pa oxygen tam sim no, thiab qhov ntsuas yuav cia li tawm ntawm lub xeev "FULL" tom qab li 5 vib nas this.
7. Rov ua cov kauj ruam 2-6 ob zaug kom txog thaum lub calibration ruaj khov.
