M256 kōwae atahanga waiariki kore whakamatao
♦ Whakataki
Ko te waahanga whakamaarama whakamaarama e pa ana ki te kaaiti karaima kaore i whakamataohia te vanadium oxide infrared detector ki te whakawhanake i nga hua whakamaarama waiariki infrared mahi nui, ka uru nga hua ki te atanga whakaputa mamati whakarara, he whai rawa te atanga, he uru urutau ki nga momo papa tukatuka mohio, me te mahi nui me te iti o te mana. kohi, rōrahi iti, ngāwari ki te āhuatanga o te whakauru whanaketanga, ka taea e te whakatau i te tono o ngā momo o te pōkākā ine pāmahana o te tono whanaketanga tuarua.
āhuatanga hua
- He iti te rahi o te hua me te ngawari ki te whakauru;
- Ka tangohia te atanga FPC, he nui nga atanga me te ngawari ki te hono atu ki etahi atu papaaho;
- iti te kohi hiko;
- Kounga whakaahua teitei;
- Te inenga tika o te pāmahana;
- atanga raraunga paerewa, tautoko i te whanaketanga tuarua, ngawari te whakauru, te tautoko i te uru ki te maha o nga waahanga tukatuka mohio.

- Kaua e pa ki te whakamahi ranei i etahi atu mea hei tukituki ki te matapihi whakakitenga;
- Kaua e pa ki nga taputapu me nga taura me nga ringa makuku;
- Kaua e whakapiko, e kino ranei nga taura hono;
- Kaua e horoia o taputapu ki te waimeha;
- Kaua e wetewete, mono ranei etahi atu taura me te kore e momotuhia te hiko;
- Kaua e hono tika te taura piri kia kore ai e pakaru nga taputapu; Tena koa kaua e wetewete i nga taputapu. Mena he he, tena koa whakapiri mai ki ta maatau kamupene mo te tiaki ngaio.
