Software Installation COMPUTERS SUPPORTED NR6 will work on any PC which can run Windows 2000, XP or Vista and which has a free USB socket. NB units, which comply with EN60950, should be used. PRINTERS SUPPORTED As these instruments operate in a Windows environment, print capability depends on you having installed a printer under Windows. Virtually any printer, which works under the version of Windows you have, will be suitable. INSTALLATION SEQUENCE The software comes on 2 CD’s and should be installed before connecting the NR6 Rhinometer to your PC. It is also advisable to close any other programs you may be running while performing the installation as you may need to close down the PC during this operation. GMI SOFTWARE Put the CD in your drive, navigate to it using My Computer/Windows Explorer, and double click on the file SETUP.EXE. Accept the defaults offered at each stage. INTERFACE BOARD SOFTWARE (Measurement Computing) Ensure the USB cable is not connected to the NR6 unit. Put the CD in your drive. If your PC is set to autorun CD’s then allow this to happen while accepting the defaults offered. The program Instacal and other driver software will be loaded to a folder called Measurement Computing. If your PC does not automatically run the CD’s installation program, click on My Computer, select and open your CD drive, and then double click on mccsetup.exe to install the programs and files. The installation program will offer defaults all of which should be accepted. INTERFACE BOARD HARDWARE The last installation operation is to have your PC identify the USB A/D convertor, which is built into the NR6 unit.. Click on START/ALL PROGRAMS/MEASUREMENT COMPUTING/INSCAL32.exe and Instacal will show no boards installed as shown overleaf.

Hardware Installation The NR6 hardware installation is concerned with the cable between the NR6 and the PC and the "plumbing" section which is concerned with the pressure and flow tubes and mask assembly. There is a single cable which links the NR6 box to the PC through the interface card. It can only be connected one way, and should already be connected. NR6 “plumbing” 1)

The NR6 box has three nozzles on it, which are colour coded Black is the pressure input. Red is the positive flow input. Green is the negative flow input.

2)

Connect the tube marked black onto the nozzle marked black. The tube marked red onto the nozzle marked red and the tube marked green onto the nozzle marked green. At the free end connect the tube marked red onto the flowhead port marked red. The tube marked green onto the flowhead port marked green and the tube marked black onto the mask port marked black, for posterior tests or on to the anterior tube connector for anterior tests

Opening the Software Start the program by clicking on its desktop icon or by clicking on START/PROGRAMS/GMI NASAL MEASUREMENTS/RHINOMANOMETER NR6 The opening window is as shown below.

A number of elements within the program can be configured to suit your application, and although you may wish to change them again later, it should be noted that fields within the Patient Information screen should not be changed after storing results for a particular subject, as the stored information may become inaccessible after that time. Full information on the alterations possible, and how to make them, are shown on the following pages.

How To Configure the Software All changes are made by clicking on TOOLS and OPTIONS. A new window named SETUP is then displayed which shows 4 tabs, each of which contain user configurable items. The four tabs are labelled:Formatting, in which you can change the colour of almost any element of the program on screen or printout. Patient Record, in which you can alter the number of fields available for information input, their size, their names and the type of characters which are acceptable. You can also tell the system to use a particular field entry as the patient file name. Rhinomanometry / Devices lets you tell the program what settings have been used for the interface card and what connections have been made to it. We do not recommend that any of the default settings are altered unless there is a good reason for doing so. Rhinomanometry / Acquisition, is the tab screen to use when you want to preset the type of measurement you want to be offered by default when you start testing. You can alter a number of parameters which are discussed in detail below. Rhinomanometry / Calculation, lets you add the display of Broms angles or Rohrer values when the boxes are ticked. Rhinomanometry / Printout, allows you to select other parameters for printing. Printout, The header text and margin details can be modified from here, along with additional outputs selected A detailed description of each of these Tab screens along with a screen image follows below:

Rhinomanometry / Acquisition Tab

The Rhinomanometry / Acquisition tab contains the settings for: Type defines whether you will be offered a Broms or Standard fixed point resistance test. You can always change at the time of testing but this facility allows a standard protocol to be offered. Side gives the option of Posterior or Anterior Right or Anterior Left testing as the default test starting point. Number of Respirations lets you set the number of breathing cycles, or Respiration’s required to complete a test. The default number is 4 cycles. Show Signal Marker, lets you switch on or off the circle which surrounds the Acquisition Spot during an Acquisition. Sampling Interval is a facility to slow down the rate at which the digital meter used during calibration changes is updated. The slide switch can be moved using the mouse, by placing the mouse cursor on the slider control and holding it down while moving the slider to the left or right. Calibrate, this button is a link to the Calibration screen, which is described separately. Show Advanced Settings allows some fundamental parameters to be altered.

thought through and understand the consequences. Clicking on the button marked Default returns the settings to the original values.

Under Advanced Settings the step size of flow or pressure change required to force the plotting of a new point is specified in Sampling Difference. The normal value is 30 units. The change in flow or Pressure Signal required to start a measurement recording is set in Sample Threshold. The Maximum Scale Value can be altered at will as it effectively increases the resolution of the displayed curve, but does not affect calibration. The normal value is 800 units. The Lateralisation Calculation can be switched on from here, for example to display Left greater than Right by 15% when Anterior test is performed.
