2. Aikace-aikace kewayon: Wannan tsari ya dace da Cedris PB-10 acidity gauge.
3. Mai aiki: Duk masu gwaji da ke amfani da sikelin.
4. Operation matakai:
4.3.1 Farawa
Line, kewaye haɗi:
- haɗuwa da transformer plug tare da ikon dubawa na acidometer;
Haɗa fitarwar lantarki tare da fitarwar biyan kuɗi ta zafin jiki, daban-daban da fitarwar da ta dace da ma'aunin acidity. Farawa:
- Haɗa wutar lantarki sauya, wato, kunna, sa kayan aiki pre-dumama minti talatin. Bude wutar lantarki cika rami, cire wutar lantarki kariya cap, wanke wutar lantarki da ruwa mai tsabta, da kuma bushewa ajiya da takarda mai tacewa.
4.3.2 Seidolis PB-10 pH ma'auni / acidity ma'auni - daidaitawa
Ma'anar kowane key a cikin dubawa:
Mode: canza maɓallin don canza hanyoyin auna pH, Mv da dangi Mv;
Setup: saita maɓallin don ** buffer, kiran lantarki daidaitawa data ko zaɓi kansa gane buffer;
Standardize: daidaitawa key don gano buffer don daidaitawa; Shigar: Tabbatar da maɓallin don tabbatar da zaɓin menu.
4.3.2.1 Latsa "Mode" maɓallin don daidaita ma'auni zaɓi zuwa pH ma'auni dubawa, danna "Shigar" maɓallin.

4.3.2.2 latsa "Setup" button sau daya, da allon nuna "Clear", nuna duk ** da ya gabata
Gyara bayanai sa'an nan kuma latsa "Shigar" key ** bayanan da suka gabata.

4.3.2.3 sanya lantarki a cikin buffer na pH = 6.86, cikakken motsawa, latsa "Standardize" key, da acidometer ta atomatik gane buffer da kuma walƙiya nuna buffer darajar, bayan cimma kwanciyar hankali jihar, ta hanyar "Shigar" key tabbatar, za a iya gyara wuri; Ma'aunin pH yana nuna ƙarancin lantarki 100.0%.

4.3.2.4 tsaftace lantarki tare da ruwa mai tsaftacewa da kuma bushewa tare da takarda mai tacewa, sa'an nan kuma saka pH = 4.0 (ko pH = 9.18) buffer, cikakken toshe, latsa "Standardize" maɓallin, acidometer ta atomatik gane buffer da kuma walƙiya nuna buffer darajar, bayan cimma kwanciyar hankali jihar, ta hanyar "Shigar" maɓallin tabbatar, za a iya gyara slope maki 1. Ma'aunin pH yana nuna karkatarwar lantarki, darajarsa ya kamata ta kasance tsakanin 95% ~ 105%, in ba haka ba yana nuna cewa ba a samun buffer ba, ya kamata a sake tsara madaidaicin buffer don gyara.

4.3.2.5 tsaftace lantarki tare da ruwa mai tsaftacewa da kuma bushewa tare da takarda mai tacewa, sa'an nan kuma saka pH = 9.18 (ko pH = 4.0) buffer, cikakken toshe, latsa "Standardize" maɓallin, acidometer ta atomatik gane buffer da kuma walƙiya nuna buffer darajar, bayan cimma kwanciyar hankali jihar, ta hanyar "Shigar" maɓallin tabbatar, za a iya gyara slope maki 2. Ma'aunin pH yana nuna karkatarwar lantarki, darajarsa ya kamata ta kasance tsakanin 95% ~ 105%, in ba haka ba yana nuna cewa ba a samun buffer ba, ya kamata a sake tsara madaidaicin buffer don gyara.
Lura: don auna ruwa partial acidity, yawanci amfani da buffer gyara slope na pH = 4.0; A maimakon haka, lokacin da aka auna cewa ruwa ba shi da alkali ko tsaka tsaki, yawanci ana amfani da buffer na pH = 9.18 don gyara ƙarancin.
4.3.2.6 Kayan aiki kammala calibration. Wanke lantarki tare da ruwa mai tsabta da kuma bushewa ajiya tare da takarda mai tacewa; Ko mayar da shi a cikin ƙudurin karewa don amfani da shi a lokacin da za a tsabtace shi a gaba.
