Mu gawo la metrology ndi calibration, kusankha zolemera zoyenera ndikofunikira kwambiri kuti zitsimikizire miyeso yolondola. Kaya zimagwiritsidwa ntchito poyesa bwino kwambiri zamagetsi kapena kugwiritsa ntchito mafakitale, kusankha kulemera koyenera sikungokhudza kudalirika kwa zotsatira zoyezera komanso kumakhudza mwachindunji magwiridwe antchito komanso kusunga miyezo yoyezera. Chifukwa chake, kumvetsetsa magiredi osiyanasiyana olondola, mitundu yawo yogwiritsira ntchito, komanso momwe mungasankhire zolemera zoyenera molondola ndi nkhani yofunika kwambiri kwa mainjiniya onse a metrology ndi ogwiritsa ntchito zida.
I. Kugawa Kulemera ndi Zofunikira Zolondola
Zolemera zimagawidwa motsatira muyezo wa International Organization of Legal Metrology (OIML) wa “OIML R111”. Malinga ndi muyezo uwu, zolemera zimagawidwa m'magulu osiyanasiyana kuyambira apamwamba kwambiri mpaka otsika kwambiri. Giredi iliyonse ili ndi zochitika zake zogwiritsira ntchito komanso cholakwika chachikulu chovomerezeka (MPE). Kulondola kwa magiredi osiyanasiyana, mitundu ya zinthu, kuyenerera kwa chilengedwe, ndi ndalama zimasiyana kwambiri.
1. Kufotokozera kwa Magiredi Ofunika a Kulemera
(1)Magiredi a E1 ndi E2: Zolemera Zolondola Kwambiri
Zolemera za giredi E1 ndi E2 zili m'gulu lolondola kwambiri ndipo zimagwiritsidwa ntchito makamaka m'ma laboratories a dziko lonse ndi apadziko lonse lapansi. Cholakwika chachikulu chovomerezeka cha zolemera za giredi E1 nthawi zambiri chimakhala ±0.5 milligrams, pomwe zolemera za giredi E2 zimakhala ndi MPE ya ±1.6 milligrams. Zolemera izi zimagwiritsidwa ntchito potumiza zinthu molimbika kwambiri ndipo zimapezeka kwambiri m'ma laboratories ofotokozera, mabungwe ofufuza, ndi njira zowerengera khalidwe la dziko. Chifukwa cha kulondola kwawo kwakukulu, zolemera izi nthawi zambiri zimagwiritsidwa ntchito poyesa zida zolondola monga ma balance osanthula ndi ma balance ofotokozera.
(2)Magiredi a F1 ndi F2: Zolemera Zolondola Kwambiri
Zolemera za F1 ndi F2 zimagwiritsidwa ntchito kwambiri m'ma laboratories olondola kwambiri komanso m'mabungwe oyesera za metrology. Amagwiritsidwa ntchito makamaka poyesa miyeso yamagetsi yolondola kwambiri, miyeso yowunikira, ndi zida zina zoyezera molondola. Zolemera za F1 zimakhala ndi cholakwika chachikulu cha ±5 milligrams, pomwe zolemera za F2 zimaloledwa cholakwika cha ±16 milligrams. Zolemera izi zimagwiritsidwa ntchito kwambiri mu kafukufuku wasayansi, kusanthula mankhwala, ndi madera owongolera khalidwe, komwe kumafunika kulondola kwambiri kwa muyeso koma osati kokhwima ngati magiredi a E1 ndi E2.
(3)Magiredi a M1, M2, ndi M3: Zolemera Zamakampani ndi Zamalonda
Zolemera za M1, M2, ndi M3 nthawi zambiri zimagwiritsidwa ntchito popanga mafakitale ndi malonda. Ndizoyenera kulinganiza masikelo akuluakulu a mafakitale, mipiringidzo yoyezera magalimoto, masikelo a nsanja, ndi masikelo amagetsi amalonda. Zolemera za M1 zili ndi cholakwika chovomerezeka cha ±50 milligrams, zolemera za M2 zili ndi cholakwika cha ±160 milligrams, ndipo zolemera za M3 zimalola cholakwika cha ±500 milligrams. Zolemera za M mndandanda uwu zimagwiritsidwa ntchito nthawi zambiri m'malo okhazikika a mafakitale ndi malo ogwirira ntchito, komwe zofunikira zolondola zimakhala zochepa, nthawi zambiri poyezera zinthu ndi katundu wambiri.
2. Kusankha Zinthu: Chitsulo Chosapanga Dzira vs. Zolemera za Chitsulo Chopangidwa ndi Iron
Zipangizo zolemerazo zimakhudza mwachindunji kulimba kwawo, kukhazikika kwawo, komanso kuyenerera kwawo kugwiritsidwa ntchito mosiyanasiyana. Zipangizo zodziwika kwambiri zolemera ndi chitsulo chosapanga dzimbiri ndi chitsulo chosungunuka, chilichonse choyenera miyezo yosiyanasiyana komanso malo ozungulira.
(1)Zolemera Zosapanga Chitsulo:
Zolemera zosapanga dzimbiri zimakhala zolimba kwambiri ku dzimbiri komanso zimakhala ndi mphamvu zapamwamba kwambiri zamakanika, zokhala ndi malo osalala omwe ndi osavuta kuyeretsa. Chifukwa cha kufanana kwawo komanso kukhazikika kwawo, zolemera zosapanga dzimbiri zimakhala zoyenera kwambiri pa magiredi a E1, E2, F1, ndi F2 ndipo zimagwiritsidwa ntchito kwambiri poyesa molondola komanso m'malo ofufuza. Zolemera izi ndi zolimba ndipo zimatha kusunga kulondola kwawo kwa nthawi yayitali m'malo olamulidwa.
(2)Zolemera za Chitsulo Chopangidwa:
Zolemera zachitsulo chopangidwa ndi chitsulo nthawi zambiri zimagwiritsidwa ntchito mu magiredi a M1, M2, ndi M3 ndipo zimapezeka kwambiri poyesa mafakitale ndi malonda. Kutsika mtengo komanso kuchuluka kwa chitsulo chopangidwa ndi chitsulo kumapangitsa kuti chikhale choyenera kugwiritsa ntchito zolemera zazikulu zomwe zimagwiritsidwa ntchito m'mabwalo oyezera magalimoto ndi zida zoyezera mafakitale. Komabe, zolemera zachitsulo chopangidwa ndi chitsulo nthawi zambiri zimakhala ndi malo owuma, omwe amatha kusungunuka ndi kuipitsidwa, motero amafunika kusamalidwa nthawi zonse komanso kutsukidwa.
II.Momwe Mungasankhire Giredi Yoyenera ya Kulemera
Mukasankha kulemera koyenera, muyenera kuganizira momwe mungagwiritsire ntchito, zofunikira zenizeni za zidazo, komanso momwe zinthu zilili pamalo oyezera. Nazi malingaliro ena ogwiritsira ntchito nthawi zambiri:
1. Ma Laboratories Olondola Kwambiri:
Ngati ntchito yanu ikuphatikizapo kutumiza zinthu molondola kwambiri, ganizirani kugwiritsa ntchito zolemera za E1 kapena E2. Izi ndizofunikira kwambiri pakuwunika bwino kwa dziko lonse komanso zida zasayansi zolondola kwambiri.
2. Ma Balance Amagetsi Olondola Kwambiri ndi Ma Balance Osanthula:
Zolemera za F1 kapena F2 ndizokwanira kulinganiza zida zotere, makamaka m'magawo monga chemistry ndi mankhwala komwe kumafunika kulondola kwambiri.
3. Miyeso ya Mafakitale ndi Masikelo Amalonda:
Pa masikelo a mafakitale, mipiringidzo yoyezera katundu wa magalimoto, ndi masikelo akuluakulu amagetsi, zolemera za M1, M2, kapena M3 ndizoyenera kwambiri. Zolemera izi zimapangidwa kuti zizigwiritsidwa ntchito nthawi zonse m'mafakitale, ndi zolakwika zazikulu pang'ono zovomerezeka.
III.Kukonza ndi Kukonza Kulemera
Ngakhale mutagwiritsa ntchito zinthu zolemera molondola kwambiri, kugwiritsa ntchito zinthu kwa nthawi yayitali, kusintha kwa chilengedwe, komanso kusagwiritsa ntchito bwino zinthu kungayambitse kusiyana kwa kulondola. Chifukwa chake, kuwongolera ndi kukonza nthawi zonse ndikofunikira:
1. Kukonza Tsiku ndi Tsiku:
Pewani kukhudzana mwachindunji ndi zolemera kuti mafuta ndi zinthu zodetsa zisakhudze pamwamba pake. Ndikofunikira kugwiritsa ntchito nsalu yapadera kuti mupukute zolemerazo pang'onopang'ono ndikuzisunga pamalo ouma, opanda fumbi kuti chinyezi ndi fumbi zisasinthe kulondola kwake.
2. Kukonza Kwanthawi Zonse:
Kuyeza nthawi zonse n'kofunika kwambiri kuti kulemera kukhale kolondola. Kuyeza kolondola kwambiri nthawi zambiri kumafunika kuyezedwa chaka chilichonse, pomwe kuyeza kwa M komwe kumagwiritsidwa ntchito poyeza zinthu m'mafakitale kuyeneranso kuyezedwa chaka chilichonse kapena theka la chaka kuti zitsimikizire kuti zikugwirizana ndi miyezo yolondola.
3. Mabungwe Ovomerezeka Oyang'anira Kuwerengera:
Ndikofunikira kusankha ntchito yovomerezeka yowerengera kulemera ndi ISO/IEC 17025, yomwe imatsimikizira kuti zotsatira za kuwerengera zikupezeka padziko lonse lapansi. Kuphatikiza apo, kukhazikitsa zolemba za kuwerengera kungathandize kutsatira kusintha kwa kulondola kwa kulemera ndikuchepetsa zoopsa zoyezera.
Mapeto
Kulemera ndi zida zofunika kwambiri poyesa ndi kuwerengera, ndipo magiredi ake olondola, zipangizo, ndi mitundu ya ntchito zimalamulira momwe zimagwirira ntchito m'magawo osiyanasiyana. Mwa kusankha kulemera koyenera kutengera zosowa zanu zogwiritsira ntchito ndikutsatira njira zoyenera zosamalira ndi kuwerengera, mutha kutsimikizira kulondola ndi kudalirika kwa njira yoyezera. Kuyambira pa E1, E2 mpaka M, giredi iliyonse ili ndi momwe imagwiritsidwira ntchito. Mukasankha kulemera, muyenera kuganizira mokwanira zofunikira zolondola, mitundu ya zida, ndi zinthu zachilengedwe kuti mutsimikizire zotsatira zokhazikika zoyezera pakapita nthawi.
