DRK156 Tijaabada Iska caabinta Dusha sare

Mitirkan jeebka lagu cabiro waxa uu cabbiri karaa cidhiidhiga dushiisa iyo iska caabinta dhulka, iyada oo kala duwanaansho balaadhan laga bilaabo 103 ohms/□ ilaa 1012 ohms/□, oo sax ah ±1/2 kala duwan.

Codsiyada
Si loo cabbiro ciribtirka dusha sare, dhig mitirka oogada si loo cabbiro, riix oo hay badhanka cabbirka cas (TEST), diode iftiin-bixiya oo joogto ah (LED) ayaa tilmaamaya cabbirka cidhiidhiga dusha la qiyaasay.
103=1 kiiloohm cagaaran
104=10k ohm cagaaran
105=100kohm cagaaran
106=1 mega ohm huruud ah
107=10 megaohm huruud ah
108=100 megaohm huruud ah
109=1000 megaohm huruud ah
1010=10000 megaohm huruud ah
1011=100000 megaohm huruud ah
1012=1000000 megaohm casaanka cas
>1012=Laydh cas oo dahaaran
Cabir iska caabinta dhulka
Geli siliga dhulka godka dhulka (Ground), kaas oo dahaadhiya korantada ogaanshaha dhinaca midig ee mitirka (dhinac la mid ah godka). Ku xidh fiilada alligator siligaada dhulka.
Dhig mitirka dusha sare si loo cabbiro, riix oo hay badhanka TEST, LED-ga iftiinka joogtada ah wuxuu muujinayaa baaxadda caabbinta dhulka. Halbeegga cabbirkan waa ohms.
heerka farsamada
Qalabku waxa uu isticmaalaa habka ASTM-ga D-257 ee isku midka ah ee dareemayaasha electrode-ka, kaas oo si fudud oo isdabajoog ah u cabbiri kara kala duwanaansho korantada, dareeraha korantada, iyo dusha dahaarka.
