Q1 Ka liʻiliʻi kahe kahe
Q2 Hoʻololi kahe kahe
Q3 Kahe kahe mau (ke kahe hana)
Q4 Ka nui o ke kahe kahe ana
E hōʻoia ʻaʻole ʻoi aku ka nui o ke kahe e hele ai ma ka mita ma mua o Q3.
Loaʻa ka hapa liʻiliʻi o ka hapa nui o nā mika wai (Q1), ma lalo ʻaʻole hiki iā lākou ke hāʻawi i kahi heluhelu pololei.
Inā koho ʻoe i ka mika nui, e nalowale paha ʻoe i ka pololei ma ka hopena haʻahaʻa o ka pae kahe.
ʻOi aku ka pōkole o ke ola a me ka pololei o nā mika e hoʻohana mau ana ma ke kahe kahe nui (Q4).
E hoʻomāhuahua i kāu mika ma ke kūpono no ke kahe āu e manaʻo ai e ana.
Lakiō huli iho R
Ua wehewehe ʻia ka pae hana metrological e ka Ratio (ʻO kēia waiwai ka pilina ma waena o ke kahe hana / kahe liʻiliʻi).
ʻO ke kiʻekiʻe o ka "R" Ratio, ʻoi aku ka nui o ka naʻau o ka mika no ke ana ʻana i nā kahe kahe haʻahaʻa.
ʻO nā kumukūʻai maʻamau o nā ratio R i ka mika wai penei:
- R40, R50, R63, R80, R100, R125, R160, R 200, R250, R315, R400, R500, R630, R800, R1000.

A e hoʻomanaʻo e pololei wale ka mika inā hoʻokō nā kūlana kaiapuni i nā koi āpau o ka mea hana e pili ana i ke kahe kahe, ka hoʻonohonoho ʻana, ka mahana, ke kahe kahe, ka vibration etc.
