ʻO ke Kaona Kaumaha ʻO ia ka waiwai kaupaona liʻiliʻi loa i hiki i kahi unahi ke hōʻoia ʻaʻohe hewa pili nui i nā hopena kaupaona.He aha ka "hiki ke kaupaona liʻiliʻi" o kahi unahi?He nīnau kēia e pono e hoʻoikaika ʻia no kēlā me kēia pālākiō i kā mākou hana hoʻomaʻamaʻa.No ka mea, aia kekahi mau unahi e hoʻohana ana i nā ʻāpana, i ke koho ʻana i nā unahi, noʻonoʻo lākou e mālama i ke kālā kūʻai, e hoʻemi i ka nui o nā unahi i kūʻai ʻia e like me ka hiki, a inā hiki iā lākou ke hoʻohana i hoʻokahi unahi e kaupaona i nā mea komo a i waho o ka ʻāpana, ʻaʻole makemake lākou e kūʻai i ʻelua mau unahi me ka mana kaumaha ʻokoʻa.
Ke kūkākūkā wale nei mākou i ka hiki ke kaupaona haʻahaʻa o "nā unahi nonautomatic", ʻaʻole ka liʻiliʻi liʻiliʻi o ke kaupaona ʻana o nā "mea unahi ʻakomi".ʻO ke kumu, ʻo kēlā me kēia o nā ʻāpana ʻeono o "nā unahi ʻokoʻa" he ʻokoʻa nā koi kaulike liʻiliʻi, a ʻoiaʻiʻo ua hoʻolālā ʻia lākou a pau e kāohi i ka pololei o kā lākou kaupaona ʻana.
Ma ka 2006 paʻi o ka International Recommendation R76 "Nonautomatic Weighing Instruments", ka palena haʻahaʻa haʻahaʻa o kēlā me kēia o nā papa kaulike ʻehā o nā unahi i kuhikuhi ʻia a kapa ʻia ʻo "Minimum Weighing Capacity (Lower Limit)".
No laila, ma ke ʻano he ʻoihana hana a me ke keʻena hoʻokele metrological pono e hoʻomaopopo i nā mea hoʻohana e pono e kau i nā unahi me nā pae kaupaona like ʻole i kā lākou ʻoihana e hōʻoia i ka hoʻohana ʻia ʻana o nā ʻano like ʻole no nā mea o nā mea kaupaona like ʻole. kupono o ka hooponopono kalepa.
Ma ke ana o Kina a me ka hōʻoia hoʻoponopono, ina paha i ka unahiʻole hiki ke hoʻokō i nā koi o nā lula pili, i ka hōʻoia mua a me ka hope o ma ka liʻiliʻi loa elima i waeia unahi, a pono e komo: ka palena iki unahiʻole, ka nui aeia hewa hoʻololi i ka unahiʻole ( 500e, 2000e no ka pae pololei waena; 50e, 200e no ka pae pololei maʻamau), 1/2 pālākiō kiʻekiʻe, unahi kiʻekiʻe.Inā he 20e wale nō ka haʻahaʻa haʻahaʻa, a i ʻole 50e wale nō, inā ʻo ka hapa i ʻae ʻia he 1 mahele calibration, ʻo ka hapa pili he 1/20 a i ʻole 1/50 wale nō.He mea ʻole kēia hewa pili i ka mea hoʻohana.Inā noi ʻia ka hoʻohana ʻana o ka ʻāpana e hoʻoholo i ka hiki ke kaupaona haʻahaʻa ma mua o 500e, ʻaʻole hiki i ke kino hōʻoia ke lilo i 500e o kēia hiki ke kaupaona no ka hōʻoia.
No ka loiloi ʻike ʻole ʻana o ka mīkini paona uila, koho ʻia ka nui o ke kaupaona ʻana, 500e, 2000e.
ʻekolu helu kaupaona, a emi iho ma lalo o 500e helu kaupaona ʻaʻole ia he loiloi o ka papahana.A laila, emi iho ma lalo o 500e helu helu o ke kaupaona pololei, hiki no hoi ke hoomaopopoia e like me ka maʻiʻo o ka loiloi, i keia manawa e haawi mai i ka "kaumaha iki" keia wahi pehea e koho i ka pahu hopu.
