4. Pohō ma ka ho'āʻo maloʻo
4.1 Mea Hana:
Umu hoʻomaloʻo thermostatic uila, 1/10,000 koena.
4.2 Kaʻina hana:
I loko o ka omole kaumaha palahalaha me ka paona mau a me ka maloo nui o ka uhi waha o ka lepo, e kaupaona i 1 gram (pololei i ka 0.0001 gram) o ka laana.Pono e hohola ʻia ka hāpana ma lalo o ka ʻōmole kaupaona me ka mānoanoa ʻaʻole i ʻoi aku ma mua o 10mm, e hoʻokomo i loko o ka umu hoʻomaloʻo uila thermostatic, maloʻo ma 105 ~ 110 ℃ no 3 mau hola, a laila neʻe i loko o ka lumi maloʻo e hoʻomaloʻo ai. lumi wela no ke kaupaona ana.
Heluhelu: Pohō ma ka maloʻo %= (M1-M2) ÷M×100
Kahi: M1: ke kaumaha o ka laʻana a me ke ana ʻōmole ma mua o ka maloʻo ʻana, grams
M2: ke kaumaha o ka laʻana a me ke ana ʻana o ka hue ma hope o ka maloʻo ʻana, i ka grams
M: Kaumaha laʻana, grams
5. Hoʻololi kikoʻī
-- Ua ana ʻia ka hoʻololi kikoʻī e like me GB/T613-1988
Laʻana hoʻomākaukau: 1.0000g hāpana ua pono kaupaona a neʻe i ka maʻemaʻe a me ka maloʻo 50ml volumetric omole, 20ml wai i hoʻohuiʻia, ka omole ua hoʻopio a hoʻoluliluliʻia e hoʻoheheʻe, a laila hoʻoheheʻeʻia i ka paona me ka wai.
Ho'āʻo: E hoʻololi i ka zero o ka gyroscope ma mua o ka hoʻāʻo ʻana, a laila e hoʻouka i ka paipu hoʻāʻo me ka hāpana hāpana, e hoʻopaʻa i ka Angle rotation, a helu i ka ʻōwili kikoʻī o ka hāpana me ke ʻano ma lalo.
