GB 12014-2009
Surface point-to-point resistance tester ke sesebelisoa sa ho lekanya sa "ultra-high resistance" sa dijithale, se sebelisang lisebelisoa tsa ho lekanya tsa microcurrent, litšobotsi tsa sona ke:
1. Adopt 3 1/2 digit pontšo ea digital, potoloho ea ho lekanya borokho, ho nepahala ho phahameng ho lekanya, ho bala ho loketseng le ho nepahetseng.
2. Sebopeho se nkehang, boholo bo nyane, boima bo bobebe, bo bonolo ho bo sebelisa.
3. E ka tsamaisoa ke betri, sesebelisoa se ka sebetsa sebakeng sa ho emisa fatše, eseng feela ho ntlafatsa bokhoni ba ho thibela ho kena-kenana le ho tlosa tlhokomelo ea mohala oa matla, se ka boela sa sebelisoa ka linako tse tsitsitseng ka ntle ho motlakase oa motlakase oa motlakase.
4. Nako e hahiloeng ka hare, senotlolo sa ho bala ka mokhoa o itekanetseng, teko e bonolo.
5.Resistance methara e fapaneng ho fihlela ho 0 ~ 2 × 1013Ω, ke ntlha ea hona joale ho ntlha ho hanyetsa tekanyo bokgoni ba ke matla dijethale seletsa. Ke sesebelisoa se setle ka ho fetisisa sa ho lekanya bophahamo ba modumo le resistivity holim'a thepa ea insulating. Qeto e phahameng ka ho fetisisa ke 100Ω.

6.Four output voltages (10,50,100,500) e fumaneha bakeng sa tlhahlobo ea ho hanyetsa ea lisebelisoa tse sa tšoaneng tsa liaparo.
7. Betri e hahiloeng ka har'a ts'ebetso e phahameng ea ts'ebetso e phahameng, qoba bothata ba ho nkela betri sebaka, boloka litšenyehelo tsa ho nkela betri sebaka.
8. Sehokelo sa ts'ebetso sa batho. Skrine se seholo, skrine ea LCD e khanyang haholo, ho phaella ho pontšo ea liphetho tsa tekanyo, ho na le pontšo ea ts'ebetso ea tekanyo, pontšo ea motlakase o hlahisoang, tekanyo ea yuniti ea tekanyo, pontšo ea square multiplier, pontšo ea alamo e tlaase ea betri, pontšo ea alamo ea misoperation, boitsebiso bohle hang-hang.
1.Tekanyo ea ho hanyetsa: 0 ~ 2×1013 (Ω)
2. Pontšo: Skrine se seholo sa linomoro tse 31/2 se nang le pontšo ea dijithale ea backlight
3. Nako ea ho lekanya: 1min ~ 7min
4. Phoso ea mantlha ea tekanyo ea khanyetso:
5. Qeto: ponts'o ea sesebelisoa sebakeng se seng le se seng e ka tsitsa, bala boleng bo tlase ba boleng ba khanyetso e tsamaellanang e lokela ho ba ka tlase ho kapa ho lekana le phoso e lumelletsoeng ea 1/10.
6. Phoso ea motlakase ea konopo ea ho qetela: phoso ea motlakase ea konopo ea ho qetela ea sesebelisoa ha e fete ± 3% ea boleng bo lekantsoeng.
7. The end button voltage ripple content: the root mean square value of the instrument end button voltage ripple content ha e kholo ho feta 0.3% ea karolo ea DC.
8. Phoso ea nako ea tekanyo: phoso ea nako ea tekanyo ea sesebelisoa ha e kholo ho feta ± 5% ea boleng bo behiloeng.
9. Tšebeliso ea matla: betri e hahiloeng ka hare e ka sebetsa ka ho tsoelang pele bakeng sa lihora tse 30. Tšebeliso ea matla ea matla a kantle e ka tlase ho 60mA
10. Phepelo ea matla: rated voltage (V) : DC 10, 50, 100, 500
Matla a matla: matla a betri ea DC 8.5 ~ 12.5V; Phepelo ea matla a AC: AC 220V 50HZ 60mA
11. Ho ea ka GB 12014-2009 --anti-static liaparo sehlomathiso A ntlha-to-ntlha ho hanyetsa teko mokhoa ditlhoko tsa A sete ea li-electrode: teko electrode tse peli 65mm bophara tšepe silindara; Thepa ea elektrode ke tšepe e sa hloekang. Thepa ea pheletso ea li-electrode ke rabara e tsamaisang, e nang le A hardness ea 60 Shore A, A botenya ba 6mm, le A volume resistance e ka tlase ho 500Ω. Electrode e le 'ngoe boima ba 2.5kg.
12. Tumellanong le FZ / T80012-2012 --- liaparo tse hloekileng tsa kamoreng ntlha-to-point ho hanyetsa litlhoko tsa mokhoa oa ho fumana sete sa li-electrode: li-electrode tse peli tsa ho lemoha. Electrode e 'ngoe le e' ngoe ea ho lemoha e entsoe ka clamp conductive le lipoleiti tse peli tsa tšepe e sa hloekang. Clamp e lokela ho khona ho sebelisa khatello e lekaneng ho tiisa sampole le ho etsa hore e fanyehe. Sebaka sa poleiti ea tšepe e sa hloekang ke 51 × 25.5mm.
