hälve, mis on tekitatud varbsisekruvikuga mõõtmise tulemusel, kui kruviku mõõtekontaktpindu kasutatakse tööetaloni, nt rõngasmõõdu läbimõõdu mõõtmiseks
error that is the error of measurement made with the two-point inside micrometer, when the measuring contact faces are employed to measure a reference standard, e.g. (gauge blocks)
This error of measurement with the two-point inside micrometer is calculated as the signed difference between the indication of the two-point inside micrometer and the reference value of the working measurement standard (setting ring).
