That is an error from the Keithley.

"Character data error"

The meter did not like something you sent it. Syntax error or something.

Check the Keithley manual with the string you are sending it.

Hi

thanks for your kind attention. Will you please check the error in syntax in the program attached because I am unable to find the function where the error will come from?

Thanks

The error comes from the 'Write GPIB' most likely, I see that you don't specify the decimal sign of your string, I altere the string formatter to make sure it's a point:

Hello

First I would like to say thanks for your kind attention. The error -140 is solved but now it gives the error -410 at same place. What is it and how can we handle this error in the program.

Thanks and regards

Have you looked in your Keithley manual to see what error -410 means?

Query INTERRUPTED

What does the Keithley manual say how one might interrupt or abort an action

So what are you doing to interrupt the query?

How are you commutating with the Keithley?

There are lines on the GPIB bus that can abort and take the  Keithley out of TALKER mode

Sending a *cls?

Sending a *rst?

Pushing front panel button on the Keithley during a query?

Hidden control char in your string like a ctrl-C

Might need to see more of your code.

Hello

I am not asking for the error 410 which is query interrupted instead I am asking for the error -140. So will you please explain about that error..

Thanks

Ton gave you an explaination for the -140 error

Do you have a Keithley manula and have you read it?
