Pono nā thermocouple platinum-iridium 10-platinum maʻamau e kūlike me ka papa ʻōnaehana hoʻolako aupuni, pono e hoʻokō ʻia nā kaʻina hana hōʻoia aupuni. Hiki ke hoʻohana ʻia nā thermocouple platinum-iridium 10-platinum papa mua e ana i nā thermocouples platinum-iridium 10-platinum papa ʻelua, papa Ⅰ, papa Ⅱ platinum-iridium 10-platinum thermocouples a me nā thermocouples metala kumu papa Ⅰ; Hiki ke hoʻohana ʻia nā thermocouples platinum-iridium 10-platinum papa ʻelua e ana i nā thermocouples metala kumu papa Ⅱ

Māhele 4 Ka mālama ʻana a me ka hoʻōla ʻana
1. ʻO ka manawa hoʻoponopono thermocouple maʻamau he 1 makahiki, a i kēlā me kēia makahiki pono e hoʻoponopono ʻia ka thermocouple maʻamau e ka ʻoihana metrology.
2. Pono e hana ʻia ka hoʻoponopono kiaʻi e like me ka hoʻohana ʻana.
3. Pono e maʻemaʻe ke kahua hana o ka thermocouple maʻamau e pale aku i ka haumia o ka thermocouple maʻamau.
4. Pono e kau ʻia ka thermocouple maʻamau i kahi kūlana haumia ʻole a pale ʻia mai ke kaumaha mechanical.
Māhele 5 Nā hana palekana i ka wā e hoʻohana ai
1. ʻAʻole hiki ke hoʻohana ʻia ka paipu hoʻokaʻawale i ka wā e kālua ai i ka mahana kiʻekiʻe. Hoʻohana ʻia ka paipu hoʻokaʻawale mua ma hope o ka hoʻomaʻemaʻe pono ʻana a me ka kālua ʻana i ka mahana kiʻekiʻe.
2. Hoʻowahāwahā ka paipu insulation i ka maikaʻi a me ka maikaʻi ʻole, kahi e hoʻohaumia ai i ka pou platinum a e emi iho ka waiwai o ka thermoelectric potential.
3. Ma ke ʻano maʻamau, e hoʻohaumia ka paipu hoʻokaʻawale thermocouple maʻamau me ka uea makepono i ka thermocouple maʻamau, a pono e hoʻohana ʻia ka paipu metala pale no ka hōʻoia ʻana o ka thermocouple metala kumu.
4. ʻAʻole hiki ke waiho koke ʻia ka thermocouple maʻamau i loko o ka umu hoʻoponopono mahana, ʻaʻole hoʻi e lawe ʻia mai loko mai o ka umu hoʻoponopono mahana. ʻO ka wela koke a me ke anu e hoʻopilikia i ka hana thermoelectric
5. Ma lalo o nā kūlana maʻamau, pono e hoʻokaʻawale pono ʻia ka umu hōʻoia no ka thermocouple metala makamae a me ka thermocouple metala kumu; inā hiki ʻole, pono e hoʻokomo ʻia ka paipu keramika maʻemaʻe a i ʻole ka paipu corundum (ke anawaena ma kahi o 15mm) i ka paipu umu no ka pale ʻana i nā Thermocouple metala makamae a me nā thermocouple maʻamau mai ka haumia o ka thermocouple metala kumu.
