Kumvetsetsa Kuchepetsa kulemera kwake

The Minimum Weighing Capacity ndiye kayezera kakang'ono kwambiri kamene sikelo ingakhale nayo pofuna kuonetsetsa kuti palibe cholakwika chochulukira pa zotsatira zoyezera.Kodi “muyeso wocheperako” uyenera kukhala wotani?Ili ndi funso lomwe liyenera kutsindika pa sikelo iliyonse muntchito yathu yothandiza.Chifukwa pali masikelo ena omwe amagwiritsa ntchito mayunitsi, posankha masikelo, amangoganizira zosunga ndalama zogulira, kuchepetsa kuchuluka kwa masikelo ogulidwa momwe angathere, ndipo ngati angagwiritse ntchito sikelo imodzi kuyeza zinthu zomwe zimalowa ndi zotuluka pagawolo, amangogwiritsa ntchito sikelo imodzi. sali okonzeka kugula masikelo awiri okhala ndi miyeso yosiyana.

Tikungokambirana za kuchuluka kwa kuyeza kocheperako kwa "masikelo osadziyimira pawokha", osati kuchuluka kwa kuyeza kwa "masikelo odziyimira pawokha".Chifukwa chake ndi chakuti magulu asanu ndi limodzi a "masikelo odzipangira okha" ali ndi zofunikira zosiyana zoyezera, ndipo ndithudi onse amapangidwa kuti aziwongolera kulondola kwa kulemera kwawo.

M’kope la 2006 la International Recommendation R76 “Nonautomatic Weighing Instruments”, mphamvu yoyezera yocheperapo ya magulu anayi olondola a masikelo amatchulidwa ndipo amalembedwa momveka bwino kuti “Minimum Weighing Capacity (Lower Limit)”.

Chifukwa chake, monga mabizinesi opangira zinthu komanso dipatimenti yoyang'anira ma metrological akuyenera kumveketsa kwa ogwiritsa ntchito sikelo kuti akuyenera kuyika masikelo okhala ndi masikelo osiyanasiyana m'mabizinesi awo kuti awonetsetse kuti masikelo osiyanasiyana amagwiritsidwa ntchito popanga zinthu za masikelo osiyanasiyana, kuti atsimikizire kukwanira kwa kukhazikika kwa malonda.

M'malamulo amakono aku China a kuyeza ndi kutsimikizira, ngati sikelo imatha kukwaniritsa zofunikira za malamulo oyenerera, pakutsimikizira koyamba ndi kotsatira kwa masikelo osachepera asanu osankhidwa, ndipo ziyenera kuphatikizapo: sikelo yocheperako, kusintha kwakukulu kovomerezeka kovomerezeka mu sikelo ( 500e, 2000e pamlingo wolondola wapakatikati;Ngati mphamvu yoyezera yocheperako ndi 20e yokha, kapena 50e yokha, pomwe cholakwika chovomerezeka ndi gawo la calibration 1, cholakwika chachibale ndi 1/20 kapena 1/50 yokha.Kulakwitsa kwachibale kumeneku kulibe tanthauzo kwa wogwiritsa ntchito.Ngati kugwiritsa ntchito unit momveka anapempha kudziwa osachepera masekeli mphamvu zoposa 500e, certification bungwe sangakhale 500e wa mphamvu yolemera izi kwa certification.

Pakuwunika kusatsimikizika kwa makina oyezera zinthu zamagetsi, mphamvu yoyezera kwambiri, 500e, 2000e nthawi zambiri amasankhidwa.

mfundo zitatu zoyezera, ndi zosakwana 500e kuyeza mfundo sikulinso monga kuwunika ntchito.Ndiye zosakwana 500e kuyeza mfundo yolondola kuyeza, Tingaonenso kuti osati zili mu kuunika, amene ayenera tsopano kuchititsa "kuchepa kulemera" mfundo imeneyi mmene kusankha cholinga.
