He taputapu ine rere tino tika te mita rere hiko-wehewehe, he mea hanga ki te hanganga motuhake o te pūoko me te kaitahuri. Ka riro mai i a ia te mātāpono ine matua o te whakaawe hiko-whakaputa, me te whakaoti rapanga tāutanga me te tono o ngā tauira whakauru, ā, ka whakamahia whānuitia i roto i ngā horopaki ahumahi uaua.

1. Hanganga Matua me te Mātāpono Mahi

• E rua ngā wāhanga matua: Ko te pūoko (kua tāutahia ki te papaanga) he ngongo ine, he irahiko, he koiri whakaoho, me te arai. Ko te kaitahuri (kua tāutahia mamao) te kawenga mō te tukatuka tohu, te whakaatu raraunga, me te putanga.
• Tikanga Mahi: Ina rere te reo kawe hiko mā roto i te papa aukume o te pūoko, ka puta he kaha hiko e rite ana ki te tere o te rere. Ka kohia e te pūoko tēnei tohu ka tukuna ki te kaitahuri mā te taura motuhake. Whai muri i te whakanui, te tātari, me te tatau, ka tukuna e te kaitahuri ngā tohu paerewa (hei tauira, 4-20mA, HART) ka whakaatu tika rānei i ngā raraunga rere.
• Whakaritenga hononga: Ka honoa te pūoko me te kaitahuri mā te taura tohu motuhake, me te tawhiti mōrahi noa o te 10-100 mita (ka rerekē i runga i te kaihanga me te tauira).

2. Ngā Painga Matua

• Tāutanga ngāwari: Mā te hoahoa wehe ka taea te tāuta i te kaitahuri ki tētahi wāhi watea, maroke, iti hoki te pokanoa, ahakoa kei te whakairihia te pūoko ki ngā wāhi whaiti, pakari, uaua rānei ki te tae atu.
• Te kaha ki te urutau ki te taiao: Kua hangaia te pūoko me ngā taumata tiaki teitei (ko te tikanga IP65/IP68) hei ātete i te pāmahana teitei, te haumākū, te wiri, te puehu, me ngā hau waikura. Ka karohia e te kaitahuri te pānga tika ki ngā āhuatanga kino, kia mau ai te mahi.
• Ngāwari te whakahaere me te tiaki: Ka taea te whakanoho i te kaitahuri ki roto i tētahi rūma whakahaere pokapū, ki te taumata kanohi rānei, hei whakahaere i te tautuhinga tawhā, te pānui raraunga, me te tiaki auau me te kore e uru atu ki te pūoko kei te papaanga.

3. Ngā horopaki tono noa

• Ngā taiao kino o te papa mahi: Pērā i ngā tipu matū, ngā whare hanga hinu, ngā tipu maimoatanga waipara rānei he nui te pāmahana, he nui te haumākū, he nui te waikura, he nui te puehu rānei.
• Ngā whakaurunga iti te wāhi: Mō ngā paipa kua tanumia ki raro i te whenua, kua tāutahia ki ngā teitei, ki ngā wāhi taputapu kikī rānei e uaua ana ki te tāuta, ki te whakahaere rānei i ngā mita whakauru.
• Ngā hiahia aroturuki mamao: Ngā kaupapa e hiahia ana kia kohia ngā raraunga pokapū, pērā i te kawe paipa tawhiti, ngā paipa ahumahi o waho, ngā raina whakaputa nui rānei.

4. Ngā Tuhipoka mō te Kōwhiringa me te Tāutanga Matua

• Te taurite taura: Whakamahia te taura tohu motuhake i whakaratohia e te kaihanga hei ārai i te whakaiti tohu, i te pokanoa hikohiko rānei.
• Tāutanga pūoko: Whāia ngā whakaritenga ōrite ki ngā tauira whakauru—kia tino rere te paipa, kia tika ngā wāhanga paipa tika (mua 10D/muri 5D), kia tika te whenua (ātete whenua <10Ω), ā, kaua e tāuta tata ki ngā papu, ki ngā takirere, ki ngā tuke rānei.
• Te whakatakotoranga o te kaitahuri: Tāutahia ki tētahi wāhi maroke, he pai te hauhautanga, me te pāmahana taiao i waenga i te -10℃~60℃, kia matara atu i ngā kaitahuri auau, i ngā taura ngaohiko teitei, i ētahi atu pūtake pokanoa hikohiko kaha rānei.
