YY321B Surface Resistivity Tester
Leka ntlha ea ho hanyetsa ntlha ea lesela.
GB 12014-2009
1.Adopt 3 1/2 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 hahelletsoeng, senotlolo sa ho bala ka boiketsetso, 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. Mefuta e 4 ea (10,50,100,500) voltage output, e loketseng mefuta eohle ea liteko tsa ho hanyetsa thepa ea 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 khanyetso: 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 mofuteng o mong le o mong e ka tsitsa, bala boleng ba bonyane ba boleng ba khanyetso bo tlamehang ho ba tlase kapa bo lekanang 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 qetellong konopo gagamalo ripple content: motso bolela lisekoere boleng ba sesebelisoa qetellong konopo voltage ripple content ha e moholo ho feta 0.3% ea karolo ea DC.
8. Phoso ea nako ea ho lekanya: phoso ea nako ea tekanyo ea sesebelisoa ha e fete ± 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 phepelo ea motlakase kantle e ka tlase ho 60mA.
10. Phepelo ea matla: rated voltage (V) : DC 10, 50, 100, 500
Phepelo ea matla: Matla a betri ea DC 8.5 ~ 12.5V
