ExtraLab Plus Cork Extraction Force and Torque Measuring System
3.3.8. Calibration
Like any laboratory equipment, the ExtraLab Plus is subject to calibrations in order to prove and
check the values acquired. If required, EGITRON can supply a Calibration Kit for ExtraLab Plus, as
referred in Annex C.
.
It is not possible to simultaneously perform calibration and tests.
Calibration is an operation with a high level of responsibility and only technical staff with
metrology knowledge should perform this operation. For this reason, the calibration

Below this, there is the load cell value, where is indicated the value obtained thru the Analogue-toDigital Converter (ADC value) and the corresponding value in daN.cm and in Kgf.cm (depending on
the load cell).
At the center there is the Conversion Function stored on the machine memory. This function is a 3rd
degree equation, used to convert the digital value (ADC) acquired from the load cell (converted by
the analogue-to-digital converter) into N (Newton). The coefficients of this function are read from
