How to install a *.llb driver for Keithley 2182A?

[aris]

What's your application? The llb file is a group of VIs which have some common use, you should call some of them according to you specific application.

I want to online monitoring a voltage signal of about several micro volts and record the data in files. I download the driver "2182 LabVIEW ver. 6 (LV) driver for Windows" from NI website. But from the many .vi files in the .llb package, I do not know which vi should I use.

Can you do me this favor?

Thanks in advance.

I have checked the llb file and found that the “One Shot Measure.vi” can get one voltage reading at a time, if you want do the continues reading, the awkward method is put it in a while circle. I am not familiar with this instrument, so I don’t know the advanced configuration about it.

Actually,the llb driver are the combinations of the different commands for specific use, if you want to control the instrument more flexible, you’d better be acquainted with the remote commands from the user manual and write it by yourself.

Thanks aris, I think I will try “One Shot Measure.vi” first.

Besides, I also wonder is it possible to get detailed information for each .vi in the llb package?  for example, I want to play the zero check function before measurement and for different measurements I want to change the sampling rates. I think these functions may contain in other .vis in the llb driver.

Should I ask Keithley or NI for the llb manual?

I think they might have not this kind of manual. Cause the llb only provides some useful functions (you can recognize it by its name) for controlling the instrument, but they might not all of the functions or say the basic functions the instrument has. If you want to use these basic functions, you still should get to know the basic commands which the user manual has described at great length.
