3) Te ara me te whakahaere aukati
Mō ētahi tohu o te 40-120 ohms, me taurite te aukati. Ka kitea te taurite aukati āhuatanga e ngā pūihi me ngā takirua rerekētanga maha.
Me mārama ngā kaihoahoa ki te tatau i te whānui o te ara me te nui o te uara ārai e tika ana. Mēnā kāore i te tika te uara ārai, tera pea ka pā kino ki te tohu, ka arahi pea ki te pirau raraunga.
4) Ngā tohu me te taurite roa
He maha ngā rārangi i roto i te pahi mahara tere-teitei me te pahi atanga. Ka taea e ēnei rārangi te mahi i ngā auau tino teitei, nō reira me tuku te tohu i te wā kotahi mai i te kaituku ki te kaiwhiwhi. Hei tāpiri, me whai āhuatanga e kiia nei ko te taurite roa. Nō reira, ko ngā paerewa tino noa e tautuhi ana i ngā uara manawanui e tika ana kia taurite ki te roa.
5) Whakaitihia te horahanga o te ara iahiko whakahoki o nāianei
Me whai ngā kaihoahoa PCB tere-teitei i ngā ture taketake, pērā i te hoahoa i tētahi paparanga whenua tonu me te whakaiti i te horahanga o te ara iahiko whakahoki o nāianei mā te arotau i te ara whakahoki o nāianei o te ara, me te whakanoho i ngā vias tuitui maha.
