6. Muaj plaub qhov hluav taws xob tso zis (10,50,100,500) rau kev sim tiv taus ntawm ntau yam ntaub ntawv khaub ncaws.
7. Lub roj teeb uas ua tau zoo heev, tsis txhob muaj teeb meem hloov lub roj teeb, txuag tus nqi hloov lub roj teeb.
8. Kev sib txuas lus ua haujlwm tib neeg. Lub vijtsam loj, lub vijtsam LCD ci ntsa iab, ntxiv rau qhov tso saib cov txiaj ntsig ntsuas, muaj kev tso saib kev ua haujlwm ntsuas, qhov tso zis hluav taws xob, qhov tso saib chav ntsuas, qhov tso saib plaub fab sib npaug, lub tswb ceeb toom roj teeb qis, qhov tso saib ceeb toom tsis ua haujlwm, tag nrho cov ntaub ntawv ntawm ib qho ntsia.
1. Kev ntsuas tsis kam: 0 ~ 2 × 1013 (Ω)
2. Zaub: 3 1/2-tus lej loj npo nrog lub teeb pom kev zoo digital
3. Lub sijhawm ntsuas: 1 feeb ~ 7 feeb
4. Qhov yuam kev yooj yim ntawm kev ntsuas tsis kam:
5. Kev daws teeb meem: cov cuab yeej tso saib hauv txhua qhov ntau thiab tsawg tuaj yeem nyeem tau ruaj khov, qhov tsawg kawg nkaus ntawm qhov tsis kam sib xws yuav tsum tsawg dua lossis sib npaug rau qhov yuam kev tso cai ntawm 1/10
6. Qhov yuam kev ntawm qhov kawg ntawm lub khawm voltage: qhov yuam kev ntawm qhov kawg ntawm lub khawm voltage ntawm lub cuab yeej tsis ntau tshaj ± 3% ntawm tus nqi ntsuas
7. Qhov kawg ntawm lub khawm voltage ripple cov ntsiab lus: qhov nruab nrab ntawm cov nqi square ntawm lub khawm kawg ntawm lub cuab yeej voltage ripple cov ntsiab lus tsis ntau tshaj 0.3% ntawm DC Cheebtsam
8. Kev ntsuas lub sijhawm yuam kev: qhov yuam kev ntsuas lub sijhawm ntawm cov cuab yeej tsis ntau dua ± 5% ntawm tus nqi teeb tsa
9. Kev siv hluav taws xob: lub roj teeb uas ua tau hauv lub tshuab tuaj yeem ua haujlwm tas mus li rau 30 teev. Kev siv hluav taws xob ntawm lub zog sab nraud tsawg dua 60mA
10. Lub hwj chim muab hluav taws xob: ntsuas qhov hluav taws xob (V): DC 10, 50, 100, 500
