DRK156 Onye Nnwale Nguzogide Elu

Igwe nyocha nke nwere obere akpa nwere ike tụọ ma mgbochi elu yana nguzogide ala, yana oke obosara site na 103 ohms/□ ruo 1012 ohms/□, na nha nha ± 1/2.

Ngwa
Iji tụọ ihe mgbochi elu, tinye mita n'elu ka a tụọ ya, pịa ma jide bọtịnụ uhie (TEST), diode ọkụ na-enwu ọkụ (LED) na-egosi ịdị ukwuu nke impedance elu a tụrụ.
103 = 1 kilohm green LED
104 = 10k ohm green LED
105 = 100kohm green LED
106 = 1 megaohm odo LED
107 = 10 megaohm odo LED
108 = 100 megaohm odo LED
109 = 1000 megaohm odo LED
1010 = 10000 megaohm odo LED
1011 = 100000 megaohm odo LED
1012 = 1000000 megaohm uhie uhie
> 1012 = ikanam uhie mkpuchi
Tụlee iguzogide ala
Tinye eriri ala n'ime oghere ala (Ground), nke na-eme ka electrode nchọpụta akụkụ aka nri nke mita (n'otu akụkụ dị ka oghere). Jikọọ obere mkpado na waya ala gị.
Debe mita n'elu ka a tụọ ya, pịa ma jide bọtịnụ TEST, LED na-egbuke egbuke na-egosi ịdị ukwuu nke iguzogide ala. Akụkụ nke nha a bụ ohms.

Ụkpụrụ nka nka
ACL385 na-anabata usoro ASTM ọkọlọtọ D-257 parallel electrode sensing usoro, nke nwere ike na-adị mfe na ugboro ugboro tụọ dị iche iche conductive, electrostatic mwepu, na mkpuchi elu.
