► 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.
Operation p [hPa] 1E-1 1E-2 1E-3 1E-3 1E-2 1E-1 [hPa] Fig. 8: Displayed pressure using correction factors Within the pressure range < 1 hPa, the display is linear. Gas and vapor mixtures Process gases are mostly mixtures of gas and vapor. Precise measuring of gas and vapor mixtures is only possible using partial pressure measurement instruments, for example a quadrupole mass spectrometer.
Operation 8.8 Monitoring the operating condition If the battery power is low, “BAT” is shown at the top left of the display. The unit can still be operated until the battery is empty and the unit switches off. Fig. 9: Low battery power display 29/42...
