2. Hanyar Duba Sauri don Masu Rarraba Mitar Zazzabi
Auna ƙarfin aiki da zafin jiki na ingantaccen bayani ta amfani da mitar ɗawainiya tare da kunna ramuwar zafin jiki. Yi rikodin ƙimar da aka nuna diyya. Daga baya, musaki ma'aunin zafin jiki kuma yi rikodin ɗanyen aiki mai ƙarfi a ainihin zafin jiki. Yin amfani da sanannen ƙididdigan zafin jiki na maganin, ƙididdige aikin da ake sa ran a ma'aunin zafi (25 ° C). Kwatanta ƙimar ƙididdigewa tare da karatun diyya na kayan aikin. Bambanci mai mahimmanci yana nuna kuskure mai yuwuwa a cikin algorithm na ramuwa na zafin jiki ko firikwensin, yana buƙatar ƙarin tabbaci ta ingantaccen dakin gwaje-gwaje na awo.

A ƙarshe, ayyukan ramuwa na zafin jiki a cikin mita pH da mitoci masu ɗaukar nauyi suna yin dalilai daban-daban.
