Whakaahuatanga Poto:

Ko te nuinga o te wā i hangaia mō te hanga i ngā ātete hiko pāmahana iti, pērā i ngā taura whakamahana, ngā whakawhiti hiko, ngā ātete mō ngā motuka, ko te pāmahana mahi mōrahi he 752°F.

Nō reira, kāore rātou e wawao ana ki te ao o ngā ātete mō ngā oumu ahumahi, e mōhio ana rātou he iti rawa te tauwehenga pāmahana o te CuNi44 (e kiia ana ko Constantan).

Ko ō rātou painga ko ēnei e whai ake nei:

1. tino pai te ātete ki te waikura

2. tino pai te ngāwari ki te whakakorikori

3. tino pai te tūhono
