Validation of combinatorial evaluation of strain-gauge amplifier linearityHiti, Miha (Avtor) strain-gauge amplifiercalibrationcombinatorial techniquevalidationThis paper describes a validation of a combinatorial calibration technique based calibration procedure for strain-gauge amplifier calibration. The deviation between two strain-gauge amplifiers at calibration using the combinatorial technique is compared to the deviation between the same two amplifiers at calibration on a force calibration machine as a transducer-amplifier chain under unchanged conditions, serving as an amplifier linearity comparator. This enables the validation to be confirmed with a suitable expanded measurement uncertainty of 3 nV/V.International Measurement Confederation20202023-08-21 14:39:05Neznano16808UDK: 621.317ISSN pri članku: 2221-870XDOI: 10.21014/acta_imeko.v9i5.970COBISS_ID: 54802947sl© author 2020
