-1 The LBA-PC is not available
0 OK
1 LBA-PC is collecting frames of data
The Ultracal operation runs for unknown amount of time depending on the camera and the LBA-
PC configuration. Poll the OperationComplete property or respond to the OnOperationComplete
event to determine when the Ultracal operation is complete.
9.3.2.7 Auto Exposure
This method is identical to clicking AutoExposure! on the LBA-PC. This method has no effect if a
previous Auto Exposure operation is not complete.
If the LBA-PC is collecting frames of data the Auto Exposure cannot start. If there is any other
problem, the Auto Exposure will not start and the LBA-PC will display an error message on the
LBA-PC display.
This method returns the following:
-1 The LBA-PC is not available
0 OK
1 LBA-PC is collecting frames of data
The Auto Exposure operation runs for unknown amount of time depending on the camera and
the LBA-PC configuration. Poll the OperationComplete property or respond to the
OnOperationComplete event to determine when the Auto Exposure operation is complete.
9.3.3 Events
All the events can fire each time the LBA-PC collects a new frame of data. If you are still processing
an event when another frame is collected then the new event is not fired. This is especially true when
using LabVIEW.
9.3.3.1 OnNewFrame
This is a generic event fired each time the LBA-PC collects a new frame of data. You can read
any desired property values while processing this event. During this event you are guaranteed all
properties correspond to the same frame of data. After return from this event property values
will change.
Please note, LBA-PC does not collect data when minimized and will not send OnNewFrame events
while minimized.
During an event, LabVIEW records the event in a queue then returns. Below is a table of various
ways to use this event.
