fluke PM2811

Hello everyone!

I have power supply Fluke PM2811. It can be operated in remote mode through GPIB (IEEE488.2).

Never worked before with type of communications and also my knowledge about LabView are on low level.

There is a LabView driver for the device, but cannot find any example of VI how to control it using LabView.

Will appreciate any suggestion!

There is in fact an example. It's the first one on the palette - flpm28xx Example. It is however, an old and unsupported driver and it does not use VISA for the GPIB communication. It should still work as long as you have an NI GPIB controller.

Thanks!

I tried that example, but there was some error 

On the device display I can see symbol REM that means it is ready to work, but LabView detects some problem with query

You can't use a VISA Resource Name for the GPIB address. As I said, the driver uses the lower level GPIB functions. Just enter the address (5) all by itself.

Thank You a lot!

I can communicate with power supply. However, another problem arises.

The power supply has two modes- constant current (CC) and constant voltage (CV). It chooses regime automatically depending on load resistance. When I used it in local mode (without GPIB connection to PC), it was operating in CC mode and it was very convenient to pick up current value. Now for some reason power supply switches to CV regime. I changed nothing in my electrical circuit (absolutely the same load), Cannot figure out why

regards, Alex

oops..

never mind)

everthing works well!

appreciate your help!
