Pūwero hau hurihuri whakauru-ā-ringa e whā-i-te-kotahi

He tino whai hua, he penapena pūngao hoki, e whakaiti ana i ngā utu whakahaere. Mā te whakamahi i te hangarau auau rerekē me te pūhiko tīwiri tino whai hua, ka āta whakarite te pūnaha i te mana putanga kia rite ki te hiahia hau tūturu, ka whakaiti i te whakapaunga pūngao me ngā utu hiko. He pai mō ngā āhuatanga whakaputa me ngā piki me ngā heke o te hiahia hau, pērā i te hanga werohanga, te takai, me ngā ahumahi kakahu me te whakamahinga hau wā poto.

He pumau te tuku hau, he pai ake te whai huatanga o te whakaputanga. Mā te pūnaha whakahaere atamai ka pumau te putanga pēhanga hau, me ngā rerekētanga e whakahaeretia ana i roto i te ±0.1 pae. He pai mō te hanga tika, te rehu, te tapahi laser, me ētahi atu āhuatanga e hiahiatia ana he nui te pumau o te pēhanga hau, e whakaiti ana i ngā aukati whakaputa, ngā raruraru kounga rānei e puta mai ana i te pēhanga hau kore pumau.
