Sigma LBA-400 Manuel D’Utilisation

All results values will be loaded into the array all the time.  Results not enabled in the LBA-PC will 
be zero.  Note there are three sets of Gauss Fit and Top Hat results.  Either the whole beam 

section, or the major and minor sections will contain valid results depending on how the LBA-PC 

is configured. 

 

9.3.2.1 LoadConfig 

This method causes the LBA-PC to load the specified configuration file.  This method takes a 

single parameter that is the file name of the LBA-PC configuration file you wish to be loaded.  

The file name must contain the full path and file name to the LBA-PC configuration file. 
You cannot load a configuration while the LBA-PC is collecting frames, during Ultracal, or during 
Auto Exposure. 
Be very sure the specified file name is a valid, accessible LBA-PC configuration file.  There are 

many reasons why the LoadConfig may fail, most of which cause the LBA-PC to display a 

message on screen.  If LBA-PC displays a message, this method will not return until you respond 

to the message. 
Reasons LoadConfig may fail and LBA-PC display an error message: 

•  The file does not exist 
•  The file does not contain a valid LBA-PC configuration 

 

This method returns the following: 

-1 

The LBA-PC is not available 

0 OK 
1 

LBA-PC is collecting frames of data 

2 

File path name is too long 

3 

Load configuration error 

 

9.3.2.2 Open 

This method initiates communication between the LBA-PC ActiveX control and LBA-PC.  You must 

call this method, or the OpenIndex method, before calling any other method or accessing any of 
the properties.  If you do not call this method, then all the properties will be zero, methods will 

have no effect, and no events will fire. 
The first caller to Open will connect to the first available LBA-PC application, the next callers will 

connect to the second LBA-PC, etc. 
If you want to specify the LBA-PC application, then use the AppInfo property and call the 

OpenIndex method.
