Whakamātautau whakapapatahi
Me whakamātautau whakatārewa ngā ngongo rino he nui ake i te 22 mm te whānui o waho, tae atu ki te 400 mm, ā, he nui ake i te 10 mm te matotoru o te pakitara. Kia whakatārewatia ngā tauira
Whakamātautau piko
Me whakamātautau piko ngā ngongo maitai kāore e neke atu i te 22 mm te whānui o waho. Ko te koki piko he 90°. Ko te radius piko he 6 ngā wā o te whānui o waho o te ngongo maitai. I muri i te piko o te tauira, kāore e whakaaetia kia puta he pakaru, he ngatata rānei ki te tauira.
Whakamātautau makarohiko
Mō ngā ngongo maitai i hangaia tika mā te whakarewa tonu i ngā pereki maitai, ngā poro rino rānei, me whakarite e te kaiwhakarato kāore he ira mā, he poke, he mirumiru hau i raro i te mata, he papaki angaanga, he paparanga rānei i runga i te kiko matotoru kua whakakīia ki te waikawa whakawhiti o te pereki maitai, o te ngongo maitai rānei.
Arotake kore-whakangaro
E ai ki te tono a te rōpū tono, ka whiriwhiria i waenganui i te rōpū tuku me te rōpū tono, ā, ka tohua i roto i te whakaaetanga, ka taea te mahi takitahi i te kimi hapa ultrasonic mō ngā ngongo maitai. Me tutuki i te hapa ā-ringa roa o te ngongo tauira tohutoro ngā whakaritenga mō te tohu whakaae C8 i muri i te tirotiro kua tohua i roto i te GB/T 5777-1996.
