6.Four output voltages (10,50,100,500) yog muaj rau kev ntsuam xyuas ntawm ntau yam ntaub ntawv khaub ncaws.
7. Cov roj teeb uas muaj peev xwm ua tau zoo, tsis txhob muaj teeb meem ntawm kev hloov lub roj teeb, txuag tus nqi ntawm kev hloov roj teeb.
8. Humanized ua haujlwm interface.Lub vijtsam loj, lub teeb ci siab LCD, ntxiv rau qhov ntsuas qhov ntsuas pom, muaj cov khoom ntsuas ntsuas, cov zis hluav taws xob tso tawm, ntsuas chav ntsuas, cov khoom sib npaug square, roj teeb tsis muaj hluav taws xob ceeb toom, tsis ua haujlwm lub tswb, tag nrho cov ntaub ntawv ntawm ib nrais muag.
1.Resistance ntsuas: 0 ~ 2 × 1013 (Ω)
2. Zaub: 31/2-tus lej loj npo nrog backlight digital zaub
3. Lub sij hawm ntsuas: 1min ~ 7min
4. Basic yuam kev ntawm kev ntsuas tsis kam:
5. Kev daws teeb meem: ntsuas ntsuas hauv txhua qhov ntau tuaj yeem ua kom ruaj khov nyeem tawm qhov tsawg kawg nkaus tus nqi ntawm cov nqi sib raug zoo yuav tsum tsawg dua lossis sib npaug ntawm qhov kev tso cai yuam kev ntawm 1/10
6. Qhov kawg khawm voltage yuam kev: qhov ntsuas qhov kawg khawm voltage yuam kev tsis ntau tshaj ± 3% ntawm tus nqi ntsuas
7. Qhov kawg khawm voltage ripple cov ntsiab lus: lub hauv paus txhais tau tias square nqi ntawm qhov ntsuas kawg khawm voltage ripple ntsiab lus tsis ntau tshaj 0.3% ntawm DC tivthaiv
8. Kev ntsuas lub sij hawm yuam kev: qhov ntsuas lub sij hawm yuam kev ntawm qhov ntsuas tsis ntau tshaj ± 5% ntawm tus nqi teev
9. Kev siv hluav taws xob: lub roj teeb built-in tuaj yeem ua haujlwm tsis tu ncua rau 30 teev.Lub zog siv hluav taws xob sab nraud yog tsawg dua 60mA
10. Fais fab mov: ntsuas voltage (V): DC 10, 50, 100, 500
