Tepuna hauKa tāuta poutū te tokotoko piston ki runga i te mīhini whakamātautau ngenge puna hau, me ngā hononga i ngā pito e rua ki raro. Ka tuhia te kaha whakatuwheratanga me te kaha tīmatanga i te huringa tuatahi o te tīmatanga, ā, ka tuhia te kaha tuarua me te kaha pēhitanga FI, Fz, F3, F4 i te huringa tuarua, ā, ka tatauhia te kaha ingoa, te kaha waku hihiri, me te ōwehenga kaha pūmau o te puna hau.
Te pakaripuna hau kua rakame raka i te āhua waenga-whānui kia kitea ai tōna kaha raka. Ko te tere ine o te whakamātautau ora o te puna hau he 2mm/min, ā, ko te kaha kōpeketanga tuaka e hiahiatia ana hei whakaputa i te nekehanga 1mm o te tokotoko piston ko te kaha raka.
I mua i te whakamātautau i te puna hau me te raka rapa, me huri kia toru ngā wā i raro i ngā āhuatanga mahi whakatauira, kātahi ka raka i waenganui o te whiu. Ko te tere ine o te whakamātautau ora o te puna hau he 8mm/min, ā, ko te kaha pēhi tuaka e hiahiatia ana hei neke i te tokotoko piston mō te 4mm ko te uara kaha raka.
Puna hauwhakamātautau ora:
Ka whakamatautauria te puna hau me te mahi rokiroki pāmahana teitei me te iti e ai ki te tikanga whakamātautau, kātahi ka whakapirihia ki te mīhini whakamātautau ora o te puna hau. Ka whakahaerehia e te mīhini whakamātautau te huringa puna hau i raro i ngā āhuatanga mahi whakatauira, me te auau huringa o te 10-16 ngā wā/min. Kaua te pāmahana o te rango puna hau i te wā whakamātautau katoa e neke ake i te 50°C.
I muri i ia huringa 10000, inehia te pūngao mō ia huringa e ai ki te tikanga whakamātautau. I muri i te 30000 huringa, me tutuki i ngā hua ine ngā whakaritenga e whai ake nei.
A. Te mahi hiri - Ina te takirere whakahaere o tepuna hauIna katia, me pai te mahi hiri o te piston kia taea ai te raka i te tokotoko piston i tetahi tūranga.
B. Te roa o te huringa - Ko te poma hau kua paahitia te whakamātautau mahi rokiroki pāmahana teitei me te pāmahana iti me tu atu ki te 200,000 whakamātautau roa o te huringa, ā, ko te whakahekenga o te kaha ingoa i muri i te whakamātautau me iti iho i te 10%.
