Calibration thiab ntsuas
Ua Calibration hauv Options
Pib dua calibration
a) Pib dua 100% calibration.
Tus neeg siv sau 0x0220 = 8
b) Pib dua 0% calibration.
Tus neeg siv sau 0x0220 = 16
c) Reset kub calibration.
Tus neeg siv sau 0x0220 = 32
1-point calibration
1-point calibration txhais tau tias calibrating lub sojntsuam nyob rau hauv lub point ntawm 100% saturation, uas yuav muab tau los ntawm ib tug ntawm cov nram qab no txhais tau tias:
a) Hauv huab cua-saturated dej (tus qauv qauv).
Cua-saturated dej (example ntawm 500 mL) tuaj yeem tau los ntawm kev tsis tu ncua (1) purging dej nrog huab cua siv lub tshuab nqus cua lossis qee hom aeration txog 3 ~ 5 feeb, lossis (2) nplawm dej los ntawm kev sib nqus stirrer hauv qab 800 rpm rau 1 teev.
Tom qab cua-saturated dej npaj txhij, raus lub sensor cap thiab kub sensor ntawm lub sojntsuam nyob rau hauv cov huab cua-saturated dej, thiab calibrate sojntsuam tom qab nyeem ntawv yuav ruaj khov (feem ntau 1 ~ 3 feeb).
Tus neeg siv sau 0x0220 = 1, ces tos 30 vib nas this.
Yog tias qhov kev nyeem ntawv kawg ntawm 0x0102 tsis nyob hauv 100 ± 0.5%, thov xyuas seb qhov kev ruaj ntseg ntawm qhov chaw sim tam sim no lossis sim dua.
b) Hauv dej-saturated cua (txoj kev yooj yim).
Xwb, 1-pt calibration tuaj yeem ua tau yooj yim los ntawm kev siv dej-saturated cua, tab sis 0 ~ 2% yuam kev yuav tshwm sim nyob ntawm kev ua haujlwm sib txawv. Cov txheej txheem pom zoo tau muab raws li hauv qab no:
i) raus lub sensor cap thiab ntsuas kub ntawm qhov kev sojntsuam hauv dej tshiab / kais dej 1 ~ 2 feeb.
ii) tawm ntawm qhov kev sojntsuam thiab sai sai qhuav cov dej ntawm qhov chaw ntawm lub sensor cap los ntawm cov ntaub so ntswg.
iii) nruab qhov ntsuas qhov kawg hauv lub calibration / cia lub raj mis nrog ib daim txhuam cev ntub dej hauv. Tsis txhob sib cuag ncaj qha ntawm lub hau sensor nrog cov dej hauv lub calibration / cia lub raj mis thaum lub sij hawm calibration kauj ruam no. Cia qhov kev ncua deb ntawm lub sensor cap thiab daim txhuam cev ntub dej yog ~ 2 cm.
v) tos cov ntawv nyeem kom ruaj khov (2 ~ 4 feeb) thiab tom qab ntawd sau 0x0220 = 2.
2-point calibration (100% thiab 0% saturation ntsiab lus)
(i) Muab qhov kev sojntsuam tso rau hauv cov dej uas muaj huab cua, sau 0x0220 = 1 tom qab DO nyeem ntawv stabilizes.
(ii) Tom qab DO nyeem ntawv dhau los ua 100%, txav qhov kev sojntsuam mus rau xoom oxygen dej (siv sodium sulfide ntxiv rau ntau tshaj ib
dej sample) ua.
(iii) Sau 0x0220 = 2, tom qab nyeem ntawv DO stabilizes (~ tsawg kawg yog 2 mins).
- (iv) Tus neeg siv nyeem saturation ntawm 0x0102 rau 1-point calibration, 0x0104 rau 2-point calibration.
2-point cal tsis tsim nyog rau feem ntau daim ntawv thov, tshwj tsis yog cov neeg siv xav tau kev ntsuas qhov tseeb hauv qhov qis DO concentration (<0.5 ppm). - Kev tswj hwm ntawm "0% calibration" tsis muaj "100% calibration" tsis raug tso cai.
Point calibration rau kub
i) Tus neeg siv sau 0x000A = ambient kub x100 (Ex: Yog ambient kub = 32.15, ces tus neeg siv sau 0x000A = 3215).
ii) Tus neeg siv qhov ntsuas kub ntawm 0x000A . Yog hais tias nws yog sib npaug rau qhov koj inputted, calibration yog ua tiav. Yog tias tsis yog, thov sim Kauj Ruam 1 dua.
Modbus RTU raws tu qauv
Hais kom ua qauv:
- Cov lus txib yuav tsum tsis txhob xa sai dua 50mS los ntawm kev ua tiav cov lus teb kawg.
- Yog tias qhov xav tau teb los ntawm tus qhev tsis pom rau> 25mS, pov qhov kev sib txuas lus yuam kev.
- Kev sojntsuam ua raws Modbus tus qauv rau kev ua haujlwm 0x03, 0x06, 0x10, 0x17

Kev tu
Kev saib xyuas kev sojntsuam suav nrog kev tu lub hau sensor, nrog rau kev ua kom zoo, kev npaj, thiab khaws cia ntawm qhov ntsuas.
Thaum qhov kev sojntsuam tsis siv, nws raug pom zoo kom khaws cov kev sojntsuam nrog nws lub hau sensor ntsia thiab lub calibration / cia lub raj mis uas muaj nyob rau hauv thawj ntim, threaded mus rau lub sojntsuam. Ib lub khob dej huv lossis lub tshuab nqus dej / ntub dej tuaj yeem txaus yog tias tsis muaj lub raj mis calibration / cia. Daim txhuam cev hauv lub calibration/storage fwj yuav tsum tau khaws cia kom noo kom tau zoo tshaj plaws.
Tsis txhob hnov qab txog lub kaus mom uas kov cov kuab tshuaj organic, khawb, thiab kev sib tsoo sib tsoo kom ntxiv dag zog thiab ua kom lub neej ua haujlwm ntawm lub hau sensor. Kev saib xyuas tshwj xeeb yuav tsum tau coj los ntxuav cov txheej txheej ntawm lub hau, kom dip sojntsuam thiab hau hauv dej tshiab, thiab tom qab ntawd coj mus rhaub kom qhuav nrog cov ntaub so ntswg. Tsis txhob so lub txheej txheej.
Hloov lub hau sensor, yog tias lub hau txheej yog faded los yog stripped. TSIS TXHOB kov lub qhov rais ntshiab ntawm qhov ntsuas qhov ntsuas tom qab unscrewing lub hau qub. Yog tias muaj cov kab mob los yog cov seem seem nyob rau ntawm lub qhov rais lossis hauv lub hau, ua tib zoo tshem lawv nrog cov hmoov dawb so. Tom qab ntawd rov ntsia hlau qhov tshiab sensor cap rau ntawm qhov kev sojntsuam.
