Ikizamini cyo kuguruka ntabwo gishingiye kumiterere ya PIN yashyizwe kumurongo cyangwa kumera. Intwaro ishingiye kubipimo byubushobozi.Umuyobozi wumuzunguruko ishyirwa kumurongo wo kwigana hejuru yikintu, ubushobozi buzaba bunini kuruta ingingo runaka.Niba hari ikiruhuko, ubushobozi buzaba buto.

Umuvuduko wikizamini nigipimo cyingenzi cyo guhitamo tester.iumwenge ikizamini cyo kuryamamo kirashobora kugerageza neza amanota ibihumbi imwe gusa, mugihe ikizamini cyo kuryamamo kirashobora gupima amanota abiri cyangwa angahe kugirango uhagarike ih cyangwa arenga kugirango urangize ih cyangwa arenga kugirango urangize ih cyangwa arenga kugirango urangize inyemu rimwe. Abashimusi (1991) basobanuye ko ubu buryo ari uguhitamo neza kubakora ibibaho bitangaje hamwe n'umusaruro wo hasi wanditseho imbibi z'imigabane yo kwimuka kugirango batinda.

Kubyifuzo byambaye ubusa, hari ibikoresho byikizamini (Lea, 1990) .Inzira nyabagendwa yaba ikwiye gukoresha ibikoresho byibikoresho byihariye. Kugeza ubu

Kubangaga ni ugukoresha igishushanyo mbonera cya reberi, kirashobora gukoreshwa mugutahura ingingo ziva muri grid
Inzego eshatu zikurikira zo gutahura mubisanzwe zikorwa:
1) Kumenyekanisha isahani yambaye ubusa;
2) Kumenya kumurongo;
3) Gutahura imikorere.
Ubuyobozi bwa Jenerali burashobora gukoreshwa kugirango tumenye ubwoko nubwoko bwinama yumuzunguruko kimwe no gusaba bidasanzwe.
Amashanyarazi rusange ni:
Umuringa
Amabati

Ubunini buri hagati ya cm 5 na 15
Kuyobora-tin alloy (cyangwa tin-copper boloy)
Ni ukuvuga, umusirikare, mubisanzwe m 5 kugeza kuri metero 5, hamwe namabati hafi 63%

Zahabu: Mubisanzwe bizashyirwa gusa kumurongo

Ifeza: Mubisanzwe bizashyirwa gusa kumurongo gusa, cyangwa byose ni ibisubizo bya feza
