Whakatakotoranga Whakamatau

kaupapa

Me whakarite kia whakatutukihia nga hua a te kamupene ki nga whakaritenga a nga kaihoko, me tuku kaupapa mo te tirotiro hua, me te whakarite kia kounga te hua.

Tuhinga o te tono

Ko tenei paerewa e pa ana ki nga hua module TFT katoa i hangaia e XX.

Taputapu Whakamatau

Miihini miihini hiko, whakamatau whakamatau, whakanui karaihe, rama rama rama, vernier caliper

Mahere tauira me te tirotiro i nga ahuatanga o te taiao

Ko te waahanga hanga (ko te tukatuka QC ranei) he tirotiro katoa mo te tirotiro tirohanga me te whakamatautau mahi hiko, a mo te rahinga inenga, tirohanga motuhake ranei, ko te waahanga tuatahi o ia tauira ka whakamatauria, ka whakamatautauhia kia 5pcs.

Ko te waahanga kounga e 5cm te waahanga mo ia tauira, ka tango i te mahere tauira tauira kotahi mo te GB / —2012 mo te tirohanga tirohanga, a ko te taumata tirotiro whanui ko te II.

Me mau e te kaitirotiro he mowhiti hiko me nga moenga e waru o ona maihao ki ona ringa e rua. Mena he LCD kaore he polarizer e piri ana, me mau katoa nga maihao ki nga potae o nga maihao.

Ka taea e te kaitirotiro te tirotiro a-kanohi, te whakataurite ranei ki te teepu whakataurite kiriata.

Tena tirohia te tauira mo te whakamatautau hiko ma te whakamahi i nga waahanga whakamatautau me te mata whakaatu.

Ko te tawhiti i waenga i nga karu o te kaitirotiro me te hua 30 ~ 40 cm. Ko te koki tirotiro tirohanga ko te ± 15 nga nekehanga i te mata o mua o te paepae whakaatu poutū me te ± 45 nga nekehanga i te mata o mua o te papa whakaatu whakapae (tirohia te ahua i raro iho nei)

Rama rama: 800 ~ 1200LUX mo te tirotiro tirohanga

Te pāmahana o te taiao: 25 ± 5 ℃

Haumaru: 25 ~ 75% RH

Tirohia te taonga

(1) Te whakamaaramatanga i nga koha tohu i ahu mai i nga papa o roto.

a) Nga waahi maama: he maama, he ira-rite tonu i te LCD i raro i te tauira pango.

b) Ira ira: I nga whero ma, maaka me nga pikitia kikorangi, nga tohu pouri me te rahi o te rahi ka kitea i te LCD.

c) 2 tohu e tata ana = 1 takirua = 2 tohu.
