Ka whakamahia e te whakamātautau pakeke Vickers te kōhao taimana, ka pēhia ki te mata o te tauira i raro i tētahi kaha whakamātautau. Ka tangohia te kaha whakamātautau i muri i te pupuri i tētahi wā kua tohua, ka ine i te roa whakarara o te kōhao, kātahi ka tatauhia te uara pakeke Vickers (HV) e ai ki te tātai.
Te pānga o te pēhitanga o te upoko ki raro
- Te whakamahi i te kaha whakamātautau: Ko te tukanga pēhi i te pane ki raro he taahiraa matua hei whakawhiti i te kaha whakamātautau kua whakaritea (pēnei i te 1kgf, 10kgf, me ētahi atu) ki te mata o te rauemi kua whakamatautauria mā roto i te kōhao.
- Te hanga i tētahi kōhao: Mā te pēhanga ka waiho e te kōhao he kōhao taimana mārama ki runga i te mata o te rauemi, ā, ka tatauhia te pakeke mā te ine i te roa hauroki o te kōhao.
E whakamahia whānuitia ana tēnei mahi mō te whakamātautau pakeke o ngā rauemi whakarewa, ngā pepa angiangi, ngā paninga, me ētahi atu, nā te mea he whānui te awhe kaha whakamātautau me te iti o te kōhao, he mea e tika ana mō te ine tika.
Hei hoahoa hanganga noa mō te whakamātautau pakeke Vickers (he rerekē i te momo pikinga o te papa mahi), ko ngā painga o te "pēhi pane ki raro" ko te whaitake o te arorau mahi me te hanganga miihini, ko ngā taipitopito e whai ake nei,
1. He mahi watea ake, he rite ki ngā tikanga tangata-mīhini
I roto i te hoahoa pēhi pane ki raro, ka taea e te kaiwhakahaere te whakatakoto tika i te tauira ki runga i te papa mahi pumau, me te whakaoti i te pa me te uta o te indenter mā te pane ki raro, me te kore e whakarerekē pinepine i te teitei o te papa mahi. He pai ake tēnei arorau mahi "runga-ki-raro" mō ngā tikanga mahi tuku iho, he pai rawa atu mō ngā tauhou, ka taea te whakaiti i ngā mahi hoha o te whakatakotoranga me te whakatikatika tauira, me te whakaiti i ngā hapa mahi a te tangata.
2. He pakari ake te pumau o te uta, he tika ake te ine
Ko te hanganga pēhi upoko he tikanga uta pakari ake (pērā i ngā tokotoko tīwiri tika me ngā ara ārahi). Ina whakamahia te kaha whakamātautau, he māmā ake te whakahaere i te poutū me te tere uta o te indentor, ka taea ai te whakaiti i te wiri miihini, te whakakore rānei. Mō ngā rauemi tika pērā i ngā pepa angiangi, ngā paninga, me ngā wāhanga iti, ka taea e tēnei pumau te karo i te whakarerekētanga o te indention i puta mai i te uta kore pumau, ā, ka tino whakapai ake i te tika o te ine.
3. Te whānui ake o te urutau o ngā tauira
Mō ngā tauira he nui ake te rahi, he āhua koretake, he taumaha ake rānei, kāore te hoahoa pane-ki-raro e hiahia kia waha te papa mahi i te kawenga nui rawa atu, i ngā here teitei rānei (ka taea te whakatika i te papa mahi), ā, me whakarite noa kia taea te whakatakoto i te tauira ki runga i te papa mahi, he mea "e manawanui ana" ki te tauira. Tērā pea ka whakawhāitihia te hoahoa papa mahi e piki ake ana e te kawenga me te whiu hiki o te papa mahi, nō reira he uaua ki te urutau ki ngā tauira nui, taumaha rānei.
4. He pai ake te auautanga o te ine
Mā te tikanga uta pumau me te tukanga whakahaere watea ka taea te whakaiti i ngā hapa i puta mai i ngā rerekētanga mahi a te tangata (pēnei i te rerekētanga o te whakarārangi ina hiki te papa mahi). Ina inehia te tauira kotahi i ngā wā maha, ka ōrite ake te āhua whakapā i waenga i te indenter me ngā tauira, ka pai ake te whakahokinga raraunga, ā, ka teitei ake te pono o te hua.
Hei whakamutunga, he nui ake ngā painga o te whakamātautau pakeke Vickers e anga whakararo ana i te pane, te pumau, me te urutau mā te arotau i te arorau mahi me te hanganga miihini, ā, he tino pai mō te whakamātautau rauemi tika, te whakamātautau tauira maha-momo, ngā whakamātautau auau teitei rānei.
