Verification, Realignment And Calibration

for screwdriving technology


Calibration is defined as the establishment and recording of deviations from accurate values by measurement tool readings under predetermined conditions (Dakks-DKD-4).  


Realignment is the procedure undertaken to eliminate known systematic deviations between measurement tool readings and accurate measurement values.   

Verification/testing/counter measurement

Verification comprises the evidence of fulfilment of defined specifications and can be carried out routinely as an intermediate examination of a measurement tool to complement the calibration.


Traceability describes a procedure through which a measurement tool’s readings can be compared at one or more stages with a national standard for relevant measurement values (Dakks-DKD-4).
