IqmGetReadings (double SensorArray(0 to 23, 0 to 2),
double OutputArray (0 to 17), double *Time)
SensorArray . . . . . . . . . . . . . . . Elements are Rate (Å/s), Thickness (Å), and
Frequency (Hz)
Negative frequency values indicate a sensor error.
OutputArray . . . . . . . . . . . . . . . Output power, 0 to 1
Time . . . . . . . . . . . . . . . . . . . . . . Time since midnight when measurement
readings were taken. If a 0 is returned, no
new readings are available. A non-zero value
indicates there is new data, with the returned
value indicating the number of readings in
the buffer. The buffer is 10 readings long. To
flush it, keep reading until there is no new
data.
4.3 LabVIEW VI Sample
A LabVIEW VI sample file for use with LabVIEW is provided on the Thin Film
Manuals CD. The LabVIEW VI sample aids in creating user-developed software,
and interfacing the IQM-233 card with other devices.
4.3.1 Getting Started With The LabVIEW VI Sample
Requirements for the LabVIEW VI sample:
 LabVIEW software version 6 or higher must be installed on the computer.
 The IQM233 DLL must be installed on the computer. Refer to section 3.2.1,
DLL Installation, on page 3-1 .
1 Insert the Thin Film Manuals CD into the computer’s CD drive.
2 Click Windows Explorer or File Explorer >> Computer >> (CD drive letter:)
INFICON Technical Documentation >> IQM-233 Card >> IQM-233 Samples.
3 Extract the contents of the IQM-233 VI Sample.zip folder.
4 Double-click the IQM233.vi file to display the IQM-233 VI Sample window. See
Figure 4-2 .
5 Click Load DLL and then click Run in LabVIEW software. The DLL LOADED
indicator should now be illuminated.
6 In the Card Setup pane, the Normal Mode indicator is illuminated when the
IQM-233 VI is interfaced to an installed IQM-233 card. To simulate an IQM-233
card, whether or not a card is installed, click Simulate (Simulate Mode
indicator illuminates).
