Māhele 1 Nānā
ʻO ka papa mua a me ka papa lua maʻamau platinum-iridium 10-platinum thermocouple i loaʻa ka pololei kiʻekiʻe maikaʻi maikaʻi kino a me nā waiwai kemika, maikaʻi ke kūpaʻa oxidation i nā wela kiʻekiʻe, kūpaʻa maikaʻi a me ka reproducibility o ka ikaika thermoelectromotive.No laila, ua hoʻohana 'ia e like me ka maʻamau ana mea ma (419.527~1084.62) °C, ua hoʻohana 'ia i ka wela magnitude transmit a me ka precision ana ana wela i loko o ke ana wela.

Mahele 4 Ka mālama ʻana a me ka mālama ʻana
1. ʻO ka manawa hoʻoponopono thermocouple maʻamau he 1 makahiki, a i kēlā me kēia makahiki e hoʻopili ʻia ka thermocouple maʻamau e ke keʻena metrology.
2. Pono e hana ʻia ka calibration nānā pono e like me ka hoʻohana ʻana.
3. Pono e ho'oma'ema'e ke kaiapuni hana o ka thermocouple ma'amau e pale aku i ka haumia o ka thermocouple ma'amau.
4. Pono e hoʻokomoʻia ka thermocouple maʻamau i kahi kūlana haumiaʻole a paleʻia mai ka pilikia mechanical.
Māhele 5 ʻO ka mālama ʻana i ka wā e hoʻohana ai
1. ʻAʻole hiki ke hoʻohana ʻia ka paipu insulation ma ke ʻano wela wela.Hoʻohana ʻia ka paipu insulation kumu ma hope o ka hoʻomaʻemaʻe ʻana a me ka hoʻomoʻa ʻana i ka wela kiʻekiʻe.
2. ʻAʻole nānā ka paipu insulation i ka maikaʻi a me ka maikaʻi ʻole, e hoʻohaumia ʻia ka pou platinum a e emi iho ka waiwai thermoelectric.
3. E hoʻohaumia i ka thermocouple maʻamau ka paipu insulation thermocouple maʻamau me ka uea makamae, a pono e hoʻohana ʻia ka paipu metala pale no ka hōʻoia ʻana i ka thermocouple metala kumu.
4. ʻAʻole hiki ke hoʻokomo koke ʻia ka thermocouple maʻamau i loko o ka umu hoʻoponopono wela, ʻaʻole hoʻi e lawe ʻia mai ka umu hoʻoponopono wela.E pili ana ka wela a me ke anu i ka hana thermoelectric
5. Ma lalo o nā kūlana maʻamau, pono e hoʻokaʻawale ʻia ka umu hōʻoia no ka thermocouple metala makamae a me ka thermocouple metala kumu;inā ʻaʻole hiki ʻole, pono e hoʻokomo ʻia ka paipu seramika maʻemaʻe a i ʻole corundum tube (ka anawaena e pili ana i 15mm) i loko o ka pahu umu no ka pale ʻana i nā Thermocouple metala makamae a me nā thermocouple maʻamau mai ke kumu metala thermocouple pollution.
