Ngaphambi kokulinganisa iziphethu zamaqabunga, thatha izithombe bese ugcina amafayela, urekhode umbala womkhiqizo kanye nemininingwane yezinto ezibonakalayo (ububanzi nobukhulu), bese ulinganisa idatha yobukhulu.
1. Linganisa iqabunga elilodwa
1） Ukulinganiswa kwezibambo kanye nama-bolts ezibambo
Njengoba kuboniswe ngezansi. Linganisa nge-vernier caliper. Qopha inombolo yochungechunge lweshidi lesipilingi seqabunga lapho kukhona khona i-clamp, ubukhulu bokubekwa kwe-clamp (L), inani le-clamp, ubukhulu bezinto (h) nobubanzi (b) be-clamp ngayinye, ibanga lembobo ye-clamp bolt (H), ubukhulu be-clamp bolt, njll.
2） Ukulinganisa ukusika kokuphela kanye nokusika kwekhoneni
Njengoba kuboniswe ngezansi. Kala osayizi b no-l nge-vernier caliper. Qopha idatha efanele yobukhulu (b) no-(l).
3） Ukulinganisa ukugoba kokuphela kanye nokugoba kokucindezela
Njengoba kuboniswe ngezansi. Kala nge-vernier caliper kanye ne-tape measure. Qopha idatha yobukhulu (H, L1 noma L, l kanye no-h.)
4） Ukulinganisa umkhawulo wokugaya kanye nengxenye eqondile
Njengoba kuboniswe ngezansi. Sebenzisa i-vernier caliper kanye ne-tape measure ukuhlola nokurekhoda idatha efanele.
2. Linganisa amehlo agobile
Njengoba kuboniswe ngezansi. Kala nge-vernier caliper kanye ne-tape measure. Qopha ubukhulu obufanele (?). Uma ulinganisa ububanzi bangaphakathi beso, qaphela ukuthi kungenzeka ukuthi kube nezimbobo zezimpondo kanye nezimbobo ezi-elliptical esweni. Kufanele kukalwe izikhathi ezingu-3-5, futhi inani elimaphakathi lobubanzi obuncane lizonqoba.
3. Linganisa amehlo eqabunga asongiwe
Njengoba kuboniswe ngezansi. Sebenzisa intambo, i-tape measure kanye ne-vernier caliper ukuhlola (?) nokurekhoda idatha efanele.
