    6 testo NanoMet Operation testo NanoMet Operation The testo NanoMet user shell consists of the testo NanoMet main window, the testo NanoMet control panel, and the CPC control window. The testo NanoMet main window contains five tabs to set measurement parameters, to select operation mode and system state, to display the measured values and to do the data saving settings.

  • Page 18: Measurement State

    The ZERO TEST state of the testo NanoMet software cannot supply ambient air to the PNC but filtered air can be provided by the testo ASET15-1 when the primary dilution air supply is turned off and neither measuring gas nor dilution air passes the evaporation tube and only dilution air enters and leaves the secondary mixing chamber.

    6.6.1. testo NanoMet Control Panel The testo NanoMet control panel is shown in Fig. 6.10. It serves to set dilution and conditioning parameters like primary and secondary dilution factors and temperatures of primary diluter and evaporation tube of testo ASET15-1. This window also allows to control the testo ASET15-1 pumps and the raw gas pump of testo MD19-3E and it provides information about the hardware status, i.e.
