How to fix err(-1074000000) - I`m trying to save data into the buffer

[Ignaciadevoto]

Hello to all,

I was introduced to an Electrometer to performance some electrical data current measurement on diodes. The electrometer is a Keysight B2987A and I'm currently trying to create a VI in Labview to automatized the equipment to make dark current measurements.

I have only basic knowledge with Labview so I'm trying to solve by error and solution step by step helping myself with Labview help and forums information related to whatever problems I have while I'm working.

Currently I have an error in my VI that i couldn't fix. The code error is -1074000000 and happen when I want to create a file directory to save the data into the buffer. My first attempt to fix this problem was upgrading the firmware of the Electrometer, but the error didn't go away.

Any one have a suggestion about what could this error mean? is something about the communication between the VI and the equipment?

Best regards to all!

ERROR

This error code is from Kiethley, not LabVIEW.

This error indicates an error related to your instrument as you can see it in this document :

Developing LabVIEW Plug and Play Instrument Drivers

Some instrument drivers has been tested for previous version of LabVIEW but they need to be updated in some cases.

You should try to send VISA basic functions with the example provided with LabVIEW and see if everything is going well. Check also that you initialize the connection with your device first. Maybe your instrument requires some functions which are not included in your specific VI. In addition, check if you're sending the right commands to your instrument and if you send them in the proper order. If you don't, this could return this kind of error.

Feel free to contact Keithley about this error since this is not a LabVIEW issue.
