I-caliper iyithuluzi elisetshenziswa ukukala ibanga phakathi kwezinhlangothi ezimbili zento: ungakwazi ukukala, ngokunemba kwehle kuze kufike ku-0.01mm, yonke into ebingeke ilinganiseke kalula nganoma yimaphi amanye amathuluzi,. Ngisho noma i-vernier ne-dial zisavame kakhulu, namuhla ama-caliper edijithali asedume kakhulu: lokhu kwenzeka ikakhulukazi ngoba kokubili kulula ukuwasebenzisa futhi kunembe kakhulu.

Khona-ke, kufanele ukhumbule ukunemba okudingayo: uma uzokwenza umsebenzi osezingeni eliphezulu nonembayo, udinga imodeli yedijithali enobuchwepheshe obuphakathi kuka-0.005 mm no-0.001 mm.
Uhlobo ngalunye lwama-caliper lunokufaneleka namaphutha, ngakho-ke ukukhetha ukuthi iyiphi kuphuma kuwe. Nansi inkomba emfushane ngezinhlobo ezivame kakhulu zaleli thuluzi ongazithola emakethe.
