Once you have use the test panel in LJControlPanel and made sure the hardware is working properly, then you move on to other software for your actual application. See "Moving forward from here ..." on the U3 Support Homepage:
You might just want to start with LJLogUD. If you do write your own program in VB, first read Section 4 of the U3 User's Guide, and then look at the VB6 or VB.NET examples:

See the description of "Write To File" on the LJLogUD page:
One is What is the value store in a .dat file in 1st column. I have attached the photo of excel sheet of that (Column A). Column B is Voltage value that i need.
If you do write your own program in VB, first read Section 4 of the U3 User's Guide, and then look at the VB6 or VB.NET examples:
My next problem is, Is there possibility to take this values to VB6 interface.

I was found the results in a DAT file. It was great for me.
And I have two problems.
1. Why there are lot of variation of the results within small time (attached). How can I get smooth curve on this results. Is there any method to do that?
2. In the same machine (that I connected Load Cell) I connected a Magnetic Encoder (RM22IC0013B10A1B08 - Website is http://www.rls.si/en...tact-5-v--15893 ). It has a serial port at the end of cable and it is connected to interfacing unit (E201 USB - Website - http://www.rls.si/en...terface--15923). That is connecting to USB port at PC. But my problem is "Is that possible to connect with Labjack Module to store data same as Load cell."
If not It is great if you can give me a guide to do this. I don't know whether this is a relavant question for you.
Because my requirement is to collect data displacement Vs Load.

What are the y-axis units on your graph? Is it raw U3 voltage, or have you scaled the data? If you have scaling I suggest you turn it off so you are looking at the raw U3 voltage. On a low-voltage channel 1 count is about 600uV, so if you see readings varying by 1 or 2 600uV steps you are getting very good data.
2. LJLogUD cannot collect data from a serial device. You could write your own program to collect data from both, or if you don't want to program you could talk to AzeoTech and see if DAQFactory can do it:

I think you need to try double ended beams. Double ended beams are very easy to connect with your devices just need to put wires and start your working. S-type load cells are commonly used in these days and a lot of companies manufacture these products and performance of these are also differ design to design.
