  • Page 27: Determining Effective Pressure With Correction Factors

    ► Read the data logging record via parameter [P:771]. 8.7 Determining effective pressure with correction factors The measurement signal in the Pirani range depends on the gas type. Pfeiffer Vacuum has calibrated the handheld measurement instrument to nitrogen (N ) or dry air. The correction factor can be used to compensate for the gas type dependency, but a deviating characteristic in the transition range is then the result.
