Figure 5.6 shows the 'Live Data' page of the webserver, for a 16-channel pressure scanner.
Figure 5.7, Live Data Page
The live data page is a means to demonstrating the correct operation of Q-Daq and testing the unit's
calibration. A measurement for pressure and temperature is shown for each channel.
There is also a reference pressure and temperature value at the bottom of the page. This value is a
duplicate of the channel selected to be the reference (see section 5.5.2).
The pressure data can be in either BAR, PSI or Pa(Pascals), this is decided on the advanced page,
but is displayed on the top right of the live data page for convenience.
The type of value shown in the labels may be selected by means of the option buttons in the righthand
frame. These are as follows:
•
Differential Pressure (Eng)
Calibrated engineering units pressure value scaled to known full scale and
relative to the reference port (selectable between ports 1 and 16).
•
Absolute Pressure (Eng)
As above, but represented as an absolute.
Values are updated automatically, once every 500ms, with the default view being Differential Pressure
(Eng). Use the Select button to start showing values from one of the other selectable options.
NOTE : The selection of differential or absolute pressures on this page or for diagnostics only. This
setting does not affect the main output stream configuration (see section 5.5.2).
