Calibration uye Kuyera
ITA Calibration mune Options
Reset calibration
a) Reset 100% calibration.
Mushandisi anonyora 0x0220 = 8
b) Dzorerazve 0% kuenzanisa.
Mushandisi anonyora 0x0220 = 16
c) Reset tembiricha calibration.
Mushandisi anonyora 0x0220 = 32
1-point calibration
1-point calibration inoreva kuenzanisa probe padanho re100% saturation, iyo inogona kuwanikwa neimwe yeinotevera nzira:
a) Mumhepo-yakazara mvura (yakajairika nzira).
Mvura yakazadzwa nemhepo (semuenzanisoample ye500 mL) inogona kuwanikwa nekuenderera mberi (1) kuchenesa mvura nemhepo uchishandisa air bubbler kana imwe mhando yeaeration ingangoita 3 ~ 5 maminetsi, kana (2) kubvongodza mvura nemagnetic stirrer pasi pe800 rpm kweawa imwe.
Mushure mekunge mweya-yakazara mvura yagadzirira, nyudza sensor cap uye tembiricha sensor yeprobe mumvura-yakazara nemhepo, uye calibrate probe mushure mekuverenga kwave kugadzikana (kazhinji 1 ~ 3 maminetsi).
Mushandisi anonyora 0x0220 = 1 , wozomirira masekondi makumi matatu.
Kana kuverenga kwekupedzisira kwe0x0102 kusiri mu100 ± 0.5%, ndapota tarisa kana kugadzikana kwenzvimbo yekuyedza yazvino kana edza zvakare.
b) Mumvura-yakazara mweya (yakanaka nzira).
Neimwe nzira, iyo 1-pt calibration inogona kuitwa zviri nyore uchishandisa mhepo-yakazara nemvura, asi 0 ~ 2% kukanganisa kunogona kukonzerwa zvichienderana nekuita kwakasiyana. Matanho anokurudzirwa anopiwa sezvizvi:
i) kunyudza sensor cap uye tembiricha sensor ye probe mumvura yakachena / yepombi 1 ~ 2 maminetsi.
ii) buritsa probe uye nekukasira kunyudza mvura iri pamusoro pe sensor cap netishu.
iii) isa iyo sensor end mu calibration / bhodhoro rekuchengetedza ine chipanje chakanyorova mukati. Dzivisa kusangana kwakananga kwekavha ye sensor nechero mvura mune calibration / bhodhoro rekuchengetedza panguva iyi yekuenzanisa nhanho. Chengetedza chinhambwe pakati pe sensor cap uye chipanje chakanyorova chiri ~ 2 cm.
v) mirira kuti kuverenga kudzikame (2 ~ 4 maminetsi) wobva wanyora 0x0220 = 2.
2-point calibration (100% uye 0% saturation points)
(i) Isa probe mumvura yakazadzwa nemhepo, nyora 0x0220 = 1 mushure mekunge kuverenga kweDO kugadzikana.
(ii) Mushure mekunge DO kuverenga kwave 100%, fambisa probe kune zero oxygen mvura (shandisa sodium sulfide yakawedzerwa kune a
mvura sample).
(iii) Nyora 0x0220 = 2, mushure mekunge kuverenga kweDO kugadzikana (~ kanenge 2 mins).
- (iv) Mushandisi kuverenga saturation pa0x0102 ye1-point calibration, 0x0104 ye2-point calibration.
2-point cal haidiwi kune akawanda maapplication, kunze kwekunge vashandisi vachida chiyero chakanyanya muzasi DO concentration (<0.5 ppm). - Kusimbisa "0% calibration" pasina "100% calibration" haibvumirwi.
Point calibration yetembiricha
i) Mushandisi anonyora 0x000A = tembiricha yepakati x100 (Ex: Kana tembiricha yepakati = 32.15, mushandisi anonyora 0x000A=3215).
ii) Tembiricha yekuverenga mushandisi pa0x000A. Kana zvakaenzana nezvawaisa, iyo calibration inoitwa. Kana zvisiri, ndapota edza Danho 1 zvakare.
