Tirohanga Whānui
Ka taea e te tuku pāmahana whakauru thermocouple te wehe me te huri
te tohu DC mai i te thermocouple (TC) ki te tohu DC. Ko tēnei hua
he mahi utu hononga makariri kua hangaia ki roto, ā, ka taea te whirihora
mā te mohio. Ka taea te whakarite i te whānuitanga tuturu o te thermocouple mā te
pūmanawa rorohiko. . Kei a ia te mahi whakaoho momotu me te
mahi whakaoho i waho o te awhe.
Me whakakaha motuhake tēnei hua, me te pūtake hiko hoki,
kua wehea ngā pūrua tāuru me ngā pūrua tāputa.
