Fluke instrument not found on NI MAX (even though it had previously worked)

[Amina1]

Hi,

I have connected a Fluke 5502E to my computer using GPIB-USB-HS+ cable.

Next I tried to detect my Fluke 5502E on NI MAX using the following steps:

My System -> NI GPIB-USB-HS+ "GPIB0" -> Scan for instrument.

But no instrument was found during the scan even though the Primary Address on NI MAX is the same as the instruments GPIB Port Address.

This is confusing as NI MAX had previously found the instrument and this only stopped working after I had connected a second instrument using a separate GPIB-USB-HS+ cable.

Would anyone be able to guide me on how to fix this?

Hi,

You don't need a second gpib usb hs. Just connect the meter to the first gpib hs with a gpib cable

Hi, 

Thank you Curt, 

But I am sadly still stuck because the NI MAX is still unable to detect instruments

Hi Amina,

I'm a little confused by this statement

"But no instrument was found during the scan even though the Primary Address on NI MAX is the same as the instruments GPIB Port Address."

The primary address of the gpib-usb hs device is 0. Correct?

This is shown in the properties tab of the gpib-usb device.

What's the primary address of the Fluke? It shouldn't be 0.

If it's not showing up on the bus, how are you reading the address in NI-MAX?

Hi Curt,

Yep the address of the gpib-usb hs device is 0

And the address of the Fluke 5502E is 0

I am reading the NI-MAX address from GPIB settings which is shown in the picture attached to this reply,

Hi,

You need to change the address of the Fluke meter to any number between 1 and 30.

Check the manual on how to change the address.

If you have another instrument on the bus at the same time the instruments addresses must be different.

Good luck

Hi, 

I managed to fix the problem by changing the host settings on my 5502E from serial to GPIB 🤭

Thank you for your help though,

Hello my friend how did you do that? I am trying to configure a fluke 52120A and chroma but NI MAX only recognize me the chroma.
I want to add the fluke 52120A and I want to change the chroma model from Instrument 0 to Instrument 1

Did you setup the 52120A bus address as described  in the user manual on page 3-3 ?
