How to program a GPIB multimeter to read voltage and send the reading data at every 1 second?

[cpaul]

I have a Keithley 2000 Multimeter connected by GPIB to a NI GPIB controller board in my computer. I want to program the multimeter to read a voltage and send the reading data at constant period af time. Is there any possible way of programming in SCPI the multimeter to do that, but using the buit-in timer of the instrument(I want a better timing precision then using the windows timer and quering everytime to read the voltage)? I read about the trigger mechanism but I can´t still figure out how to do this. Please give me a sample of scpi code that does that, if you can!
Best Regards, Paul Cusmin.

Hi Paul,

There are a couple of instrument drivers available on the instrument driver network for the Keithley 2000.

You can use the instrument driver functions or use the source code to determine what commands are sent. For example, The LabVIEW plug and play driver has a VI for multi read, which is what you are looking for.

Hope this helps out.
