VISA miscellaneous error

[Hemagopal]

Hello,

I use VISA pallete VIs to communicate with my device (KIKUSUI HV tester equipment)

When I start a test, I will Open VISA reference and at the end of test, I will Clear and Close the VISA reference.

I go back to another screen and again come back to start test, I get VISA error. Error number is -1073807360 which Unknown miscellaneous error on VISA.

Then I have to quit the application and reopen the application to run test again.

Is there any way to close all VISA references?

This error does not occur every time but happens randomly.

Mostly, I get error when I exit the test screen after closing VISA reference and come back to test screen by opening VISA reference again. At this point when I open reference, I get error.

Thank you

Hema

Hi Hemagopal,

A couple of thoughts:

• Does your device have some shutdown command that you can/must send?
• Can you share the code you're using (ideally the opening/closing of the VISA reference, along with perhaps a simplified command that shows the error)?
• Can you upload the manual for your device (especially anything regarding the communication protocol)?

That might make it easier to help you with specifics.
