YY321B Choyesera Choletsa Kukhazikika Pamwamba
Yesani kukana kwa nsonga kuchokera ku nsonga kupita ku nsonga ya nsalu.
GB 12014-2009
1. Konzani chiwonetsero cha digito cha manambala atatu ndi theka, dera loyezera mlatho, kulondola kwambiri pakuyeza, kuwerenga kosavuta komanso kolondola.
2. Kapangidwe konyamulika, kakang'ono kukula, kopepuka kulemera, kosavuta kugwiritsa ntchito
3. Chidachi chingagwiritsidwe ntchito ndi batri, chidachi chingagwire ntchito ngati chayimitsidwa pansi, osati kungowonjezera mphamvu yoletsa kusokonezedwa ndikuchotsa chisamaliro cha chingwe chamagetsi, komanso chingagwiritsidwe ntchito nthawi zina pamagetsi olamulira magetsi akunja.
4. Nthawi yokhazikika, loko yowerengera yokha, mayeso osavuta
5. Kuyezera kokana mpaka 0 ~ 2×1013Ω, ndi luso lamakono loyezera kukana mpaka kufika pa mfundo ndi chida champhamvu cha digito. Ndi chida chabwino kwambiri choyezera kukana kwa voliyumu ndi kukana kwa pamwamba pa zinthu zotetezera kutentha. Chisamaliro chapamwamba kwambiri ndi 100Ω.
6. Mitundu 4 ya (10,50,100,500) ya mphamvu yotulutsa, yoyenera mitundu yonse ya mayeso okana zovala.
7. Batire yomangidwa mkati mwake yomwe imatha kubwezeretsedwanso bwino, pewani vuto losintha batire, sungani ndalama zosinthira batire.
8. Mawonekedwe a ntchito yopangidwa ndi anthu. Chinsalu chachikulu, chophimba cha LCD chowala kwambiri, kuwonjezera pa chiwonetsero cha zotsatira zoyezera, pali chiwonetsero cha ntchito yoyezera, chiwonetsero cha voteji yotulutsa, chiwonetsero cha gawo loyezera, chiwonetsero cha sikweya chochulukitsa, chiwonetsero cha alamu yamagetsi otsika batire, chiwonetsero cha alamu yolakwika, chidziwitso chonse mwachidule.
1. Muyeso wotsutsa: 0 ~ 2×1013 (Ω)
2. Chiwonetsero: Chinsalu chachikulu cha manambala 31/2 chokhala ndi chiwonetsero cha digito cha backlight
3. Nthawi yoyezera: 1min ~ 7min
4. Cholakwika chachikulu pakuyesa kukana:
5. Kusasinthika: chiwonetsero cha zida mu range iliyonse chikhoza kukhala chokhazikika werengani mtengo wocheperako wa mtengo wofanana wotsutsa uyenera kukhala wochepera kapena wofanana ndi cholakwika chovomerezeka cha 1/10.
6. Cholakwika cha voteji ya batani lomaliza: cholakwika cha voteji ya batani lomaliza la chida sichiposa ± 3% ya mtengo wovoteledwa
7. Kuchuluka kwa voteji ya batani lomaliza: kuchuluka kwa voteji ya batani lomaliza la chida sikoposa 0.3% ya gawo la DC.
8. Cholakwika cha nthawi yoyezera: cholakwika cha nthawi yoyezera cha chida sichiposa ±5% ya mtengo wokhazikitsidwa.
9. Kugwiritsa ntchito mphamvu: batire yomangidwa mkati imatha kugwira ntchito mosalekeza kwa maola 30. Kugwiritsa ntchito mphamvu yamagetsi akunja ndi kochepera 60mA.
10. Mphamvu: voteji yovotera (V): DC 10, 50, 100, 500
Mphamvu yamagetsi: Mphamvu ya batri ya DC 8.5 ~ 12.5V
