R76 - 1 Te Taunakitanga International mo te Kore - Aunoa Taonga taumaha Ko te tohu kore me te kore e whakatakoto i tetahi take tino nui, engari ko nga whakaritenga hangarau, engari ko nga whakaritenga hangarau, na te mea ko te pumau o te kaupapa o te taumaha. Ko nga tikanga e whai ake nei e pa ana ki te tohu kore, ka whakamarama matou, te tātari i te waa.
(1) Ko te hapa whakapuakitanga: te rereketanga i waenga i te uara o te tauine me te uara pono o te papatipu e rite ana (te huihuinga).
(2) Ko te tauine ka taea: mo te tauine kei roto i te turanga tohutoro, kua whakatauhia ki te kore e utaina ana, ko te uara tika ranei i whakatauhia e te papatipu paerewa ranei.
(3) Pūrere Zeroning: he taputapu e whakanoho ana i te uara kua tohua ki te kore kaore he kawenga i runga i te kaiwhakatere. Mo nga pauna hiko, tae atu ki: Semi - Pūrere Zeroning aunoa, taputapu kore-aunoa, te taputapu kore-aunoa, te taputapu aroturuki kore.
(4) Te tika o te tika: I muri i te korenga o te tauine, ko te hua o te kore o te hapa Zero i te hua o te taumaha kei roto i te ± 0.25e.
(5) Ko te Hapa kore: I muri i te tango i te waahanga kore o te tauine e whakaatu ana i te hapa uara, ko te hapa nui e whakaaetia ana i te waahanga o te ± 0.5e i te wa tuatahi.
(6) Pūrere Aroturuki Zero: he taputapu e mau tonu ana i te kore utu i roto i tetahi waahanga. Ko te taputapu Aroturuki Zero Zero he taputapu kore aunoa.
Ka taea e te taputapu Aroturuki Zero te wha nga whenua: Kaore, kaore e rere, rere, mai i te awhe mahi.
Ka whakaaetia te Pūrere Zero Zero ki te whakahaere i te:
- Ko te uara kua tohua he kore, ko te rite ranei o te uara taumaha kino ina he kore te taumaha o te taumaha;
- a ko te toenga he pumau tonu;
- Ko te whakatikatika kaore i nui ake i te 0.5 e / s.
1.. Zero Aroturuki Pūrere
Ka rite ki te nuinga o te toenga toenga hiko i Haina i tenei wa, he tika te whakamahi i te waahanga kore o te hapa, me whakarite e kore e taea e koe te whakahaere i te mahi kore. Na, ko te taputapu hopu kore "kaore e rere" ko te huarahi anake ko te tuku i tetahi taumaha o te uta i te taha o te waahi kore, na reira ko te ZERO te aroturuki i tua atu o tana waahanga whakahaere.
(1) Whakatauhia te reanga whakatikatika o te taputapu aroturuki ZERO
Na te mea kaore i te whakatauhia nga tikanga o te paerewa whaihua me nga tikanga a-tuhi i roto i tenei tikanga, kia kaha ai te kounga o te taumaha, kia pai ai te kounga o te hua o te hua takitahi. Mo tenei take, i whakarapopototia te kaituhi i roto i nga mahi tuuturu, ka taea e koe te tere i roto i te mara hei tirotiro i te reanga aroturuki kore o te tauine.
Tahuri ki te mana, kia kaha mo te 30min neke atu i te 10e i runga i te kawe kawenga, kia puta ai te tauine "kore" i te awhe mahi. Me ata tono i te 0.3e utaina i nga waa e pa ana ki te 2s ka kitea te uara.
I muri i te 3 Executive 0.3e kawenga, e whakaatu ana te tauine i tetahi waahanga nui o te wehewehe, e tohu ana kaore e whakahaere te taputapu.
Mena kaore i te rereke te tauine i muri i te 3 nga kawenga o te 0.3e, kei te whakahaere tonu te waeine me te whai i nga whakatika i roto i te 0.5e / s.
Na, ka ata tango i te 3 0.3e taumaha me te tauine me whakaatu he tino heke iho i te wehewehe.
He aha te 3 0.3e e whakamahia ana nga kawenga?
Ko te utunga 0.3e he iti ake i te reanga whakatikatika o te 0.5e / s; Na ko te 3 0.3e nga taumaha he nui ake i te 0.5e / s me te iti iho i te reanga whakatikatika o te 1e / s (na te mea ko te reanga whakatikatika e hiahiatia ana i te 0.5e / s Intervals).
(2) Whakauruhia kia nui te taumaha i tua atu o te Whanui Aroturuki Zero
R76, i te wa o te whakamatautau, e hiahiatia ana he kawenga 10E kia whakanohohia ki tua atu o te raarangi aroturuki ZERO. He aha e kore ai e 5e e utaina ana, he aha e kore e 2e uta?
Ahakoa i roto i nga taunakitanga o te ao me o maatau ture whaitake ko te reanga whakatika o te Zero me "0.5e / s", engari he maha nga taonga pauna o te taputapu whakatikatika o te taputapu aroturuki ZERO i tenei wa. Ahakoa etahi o nga kai-patu pauna, i whakaritea ki te reanga whakatikatika teitei (ka kite i te reanga whakatikatika teitei o te 6e / s).
2. Tirohia te Tirohanga Uru
If the weighing instrument does not have zero tracking function, or there is a special switch to close the zero tracking device, in the detection of “zero accuracy” and “zero error”, there is no need to put additional load (10e). The problem is that most of the weighing instruments in China are not equipped with a switch that can close the zero tracking device, and they all have the zero tracking function, so in order to get the zero error, we have to put an additional load (10e) to make it go beyond the zero tracking range when the scale is unloaded, so that we can get the accuracy of the zero setting “near zero” and the “zero error”. This results in a “near zero” zeroing accuracy. Sequentially place 0.1e additional weights until the value increases significantly by one division (I+e), and the total of the additional weights is ∆L, so that the zeroing error is: E0=10e+0.5e-∆L-10e=0.5e-∆L≤±0.25e. If the total of the additional weights is 0.4e, then: E0=0.5e-0.4e=0.1e<±0.25e. .
3. Meaning of determining zeroing accuracy
Ko te kaupapa o te whakatau i te tika o te tautuhinga Zero ko te whakarite ko te tatauranga o te "Ko te he mo te whakatau i mua i te whakatikatika" kua oti i roto i te mahinga whakamaoritanga. I te tirotiro i te tika o te tauine, ka taea te whiwhi i te he mo te whakatau whakatikatika e te tauira: e = 0.5e - - Kia mohio ai te he o te he i te waahi pauna motuhake o te tauine, he mea tika kia whakatikaia e te huringa kore, i.e.: E0≤mpe.
I muri i te whakatikatika i te hapa o te kaupapa pauna na te hapa o te korenga o te korenga, ka taea te whakatika i te uara e paku ana ki te tohu, ki te whakatika ranei i nga uara e tika ana i roto i nga waahanga whai mana. Heoi, ahakoa ko te whakatikatika he tohu, he koretake ranei, ko te kaupapa o te whakamahi i nga hapa kore e whakatika ana i nga raraunga ka tata ki te tika o te tauine.
4. Ko te Whakataunga Hapa Zero
Ko te mea tuatahi, me whakatau te huringa kore o te tauine i tenei ara: Tuhinga o mua. Mena ka piki ake te taumaha o te taumaha ki te 0.8e, katahi: e0 = 0.5e - 0.8e = 0.8e<±0.5e.
