This function can be used for an analyzer back up or if you wish to sup- ply the analyzer information to a computer program or another ana- lyzer.
USER MANUAL NOVAplus The created file has a column header with the following information: Site number, Date/Time, Measuring program name, Fuel type, CO2max, O2reference, and all measured values that the analyzer can measure as well as the soot numbers, Derivate and T-Boiler.
USER MANUAL NOVAplus ► With F2 = "measured value" are displayed the measured data of the stored measurement in detail, available in 3 measuring value pages, as they are defined in the measuring value window. ► With ESC you return to the context information of the measurement.
What is necessary for a data transfer to a sweeping district manage- ment program? The data memory can be transferred to a PC via USB. The MRU-ZIV module is required for this. Which requirements are necessary on the PC? The Analyzer must be registered on the PC as a HID conform device.
Page 69
Please contact the developer of the program. How do I have to install the MRU-ZIV module? The software MRU-ZIV module can be found on the MRU product CD in the Software folder. During installation, the manual for the MRU-ZIV mod- ule is stored on your hard disk, which you can print out if necessary.
USER MANUAL NOVAplus 9 Extras / Adjustments The analyzer is delivered in a standard software configuration which should cover most needs. However, there are many ways to tailor the settings to your individual needs if required. The possibilities are highly flexible and individual adaptable.

USER MANUAL NOVAplus 9.5. Performing leak test With the leak proof test, the system is checked by the device (incl. the condensate separator) up to the probe spike on undensity. The internal gas pump generates in addition a subpressure which is measured over the built-in draft sensor and is observed for a period of 10 seconds.
USER MANUAL NOVAplus If of the leak proof test is not passed the probe must be checked includ- ing the hosing as well as the condensate separator. If no undensity is ascertained in these external parts the analyzer has to be checked in a service department (worldwide service departments see www.mru.eu).
