1 Operation 1.1 Overview Tabs Pressure Last refresh of the measurement Reading (depends on tab) Information field Link to the Inficon Cube web pages The information field displays the following: 1.2 Tab • Serial number of Cube • Part number of Cube configuration • Software version • LAN settings • WLAN settings.
Stop / start refreshing the measurement value Checking the box stops the data refresh. Any zoom will remain in effect. Unchecking the box will resume normal refresh. The graph is automatically updated to display all data. Measurement point with time / pressure reading Zooming in the graph vertically (pressure) Move the mouse on the measurement line, the time and pressure values at this point (indicated by a circle) are shown.
Zooming in the graph horizontally (time) Click and hold with the left mouse button in the selected time range and drag the mouse horizontally (on time axes) to the desired size. The horizontal zoom can be reset by double-clicking into the graph. Saving pressure trend 1.3 Tab The pressure trend of the displayed data can be saved as a CSV file by clicking on the button. A dialog box opens and the file can be saved locally.
1.5 Tab • Zoom of high resolution analog output. An arbitrary range can be zoomed. The lower limit of the selected pressure range is displayed at the analog output with 0.0 V, the upper limit with 10.0 V. The values between these limits are automatically scaled. First enter the high mark, then the low mark before setting the zoom to On. Activating/deactivating the zoom by selecting On or Off. Setting the values takes approx. 3 s. 1.
Conversion time capacity / voltage Higher value: Less noise, but slower reaction to pressure steps. Temperature compensation Activate/deactivate compensation for temperature fluctuations by selecting On or Off. Switching this option off will deactivate the temperature compensation of Cube. The user has to take care for the correct treatment of the pressure data. In an unstable environment, it is recommended to leave this option at On.
Second Stage Filter In situation of very long static measurements, the data can be further smoothed by applying a secondary stage filter. If a Second Stage Filter is applied, the CDC and the Adaptive Filter settings are adapted accordingly. Moving Exp AVG: Exponential moving average. Savitzky-Golay: Symmetrical filter of 4th order with nL= nR = 5. Loess: Locally weighted scattered data smoothing.
1.8 Tab • Settings for LAN and WLAN • Backup and restore of user settings • Factory Reset LAN Settings The IP address / Subnet of the LAN interface can be changed. Clicking will open a confirmation window. The gauge will reboot after clicking on . WLAN Settings Cube can be connected to a wireless access point using DHCP. Ad hoc connections are not possible. With , Cube searches for accessible networks.
1.9 Tab • Firmware upgrade The button opens a file dialog in which the upgrade file, e.g. "SilverlineFactory-Vxxxxx.zip" can be selected. The new firmware is transmitted to the gauge by clicking . An automatic reset of the gauge is performed, if the upgrade was successfully. Updating the firmware takes approx. 3min. The new firmware version is displayed on the left side in the information section under the Cube image. tira92e1-a (2014-07) CDGsci Web Interface.
