how to set a source voltage and measure current using GPIB

[sak16091991]

Hello everyone,

I am using LabVIEW 13 and GPIB for communicating with the device keithley 2410.

I made a program of staircase sweep programming with the help of keithley 2400 user manual but on interfacing it is giving "error code-120" i.e. numeric data error.

Can anyone please tell me how to remove this error and also check my program with the commands.

Regards

Hi sak,

you should determine the exact command which yields that "error -120" message of the Keithley.

ymanglik should be able to explain the procedure by now, he uses the same device with similar problems 🙂

I guess it's related to that part of code:

What's the reason to use FormatIntoString here? Why add a constant number to the string? Why not just write the number in the string constant? Where should the number be attached? Right at the end?

Btw. you don't need that sequence structure - it's all in the DATAFLOW!

Hello everyone,

I made this program of keithley 2410 for source V and measure I. It is woking but when i give negative voltage so it doesn't work so please tell me which command I should use to set negative range of voltage.

I am sending you my code.(attached)

urgentlly!!!

Hi sak,

why do you have the exactly same problem as ymanglik? At the same time? Just coincidence?

Are you the same person as ymanglik or are you working in the very same team?

Please don't create double posts for the very same topic!

You already got a link to ymanglik's thread so please read that thread and follow all suggestions made over there!

Hello GerDs,

I dont know ymanglik about whom you are talking.

My program is running fine with MIN, MAX, START and STOP parameters but as I go for numeric values , I get numeric error. So please tell which command I should use to debug this problem.

Hi sak,

did you read ymangliks thread? We already told him how to solve those problems - in several messages of that thread!

Even when you don't know him: you both have the same problem and you both need to take the same steps to solve it.
