fluke 8842A getting started application

[makhan]

I have connected a fluke 8842A multimeter at address 23 to my computer and when I view the VISA properties of the same it shows GPIB0::23::INSTR. First I have tried to use the GPIB write but it doesnt work, it just reads and the application never finishes. Then I downloaded the instrument driver and run its "getting started application". It only requires a valid GPIB address which in my case is 23. But after putting the address, I get the following error message, "VISA OPEN IN FLUKE 884XX/INITIALIZE.VI". Can someone please guide me as to where the mistake might be, since all the process is automated except the address string which is taken as an input...

Hi,

You could try a couple of things.

In Measurement & Automation, Click on the Devices and Interface folder, then select the GPIB card (GPIB0). Then click on the Scan For Instruments. After a few minutes you should get a list Instrument in the right hand side of the screen of Measurement & Automation (MAX). Check if address 23 is there and if it is the Fluke 8842A.
If it there and not the fluke then you will need to change the addresses of one of the instruments to get rid of any conflict.

(You dont say if any other instruments are also connected).

If it not present and you are sure it is connected properly. If other instruments are addressed correctly, then try changing the bus cable to the fluke.

Re check the Interface settings on the instrument. Make sure its
not set for RS232 interface (if it has that capability).


Hope this gets you going.

Hi there..
I am also working on the fluke multimeter. I think you are having problem with address initialization.
Pls try these steps.

1. Launch the Measurement and Automation Software and make a scan for the connected instrument(S) to your PC.
2. Take note of the PAD (Primary Address= ?). You may change the address on the fluke 8842A by refering to the "dip switches" behind the instruments.
3.Then, launch the instrument driver (LabView)which you have downloaded and check the "resourse name" (e.g. GPIB::??::INSTR).You can edit to match your instrument(s) address.
4. Other than that,just make sure you do not set the same address for every instruments you connected.

I hope it helps.
