Calibration thiab ntsuas txoj kev ntawm portable yaj oxygen meter
1. Saib seb cov zaj duab xis ntawm lub hau electrode puas puas. Yog tias muaj kev puas tsuaj, hloov tus thawj electrode cap, ntxiv electrolyte rau lub tshiab electrode cap, 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 pob "ON / OFF" kom qhib lub zog, qhuav cov electrodes, thiab ua tib zoo nqus cov dej noo ntawm cov yeeb yaj kiab.
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 ( lo lus CONC yog tso tawm nyob rau hauv sab laug ces kaum), nias lub khawm "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 dua cov kauj ruam 4.2-4.6 ob zaug kom txog thaum lub calibration ruaj khov.
8. Yog tias lub ntsuas ntsuas tsis tuaj yeem rov qab mus rau xoom tom qab rov ua kom rov ntsuas dua lossis qhov ntsuas tag nrho ntawm cov pa oxygen uas muaj nuj nqis qis dua 7mg/L, hloov lub electrode tshiab thiab rov ua cov kauj ruam 4.2-4.6.
Portable dissolved oxygen meter ntsuas:
Nias "ON/OFF" kom qhib lub hwj chim thiab ncaj qha mus rau hauv lub xeev ntsuas (CONC tso tawm kom pom nyob rau hauv sab laug ces kaum). Muab cov electrode tso rau hauv qhov kev daws teeb meem los kuaj, thiab sau ntawv tom qab kev nyeem ntawv ruaj khov.
