Keithley RS232 Multiple Channels into array

[DennisKnutson]

There is no Delphi code anywhere in any of your images. The mention of Delphi is just silly.  Delphi is a text based programming language - you are using LabVIEW!

You still have the ability to download the LabVIEW code that is already written for your instrument. Since you are not familiar with LabVIEW or the instrument, I don't understand why you are trying to start from scratch.

Hi,

I am using ''Keithley 27XX Finite Multi Read/ Single Measurement'' (The plug and play drivers) for front and rear panel measurement. As far as the front panel is concerned I can measure all the parameters, But while using the rear panel with 7702 module I can only measure DC Voltages and nothing else (ACV, DCi,DCV,Resistance etc). Every time I try to measure some thing other than DC voltage I get an error message, error-221(Settings conflict). I am attaching the file too. I have only attached the results from 2 examples but tried this with every one of them. As you can see for every example the DCV is being measured but measuring anything else gives an error. 

Thank you

It's been quite a while since I've dealt with Keithley instruments, but I believe you have to manually select the rear inputs before you can actually use them.

Yes that is true and if not selected manually the LV program gives an error. I do select that and am able to scan the channels and record DC Voltages but nothing else. That is the problem.
