Labview on Keithley 3706 multimeter

[khiam]

Is there anyway to measure multiple channels at one go and receive the readings in the labview?

Currently I'm only able to close multiple channels in the switch(3730) but only could measure 1 channel at a time. What I'm measuring is 2 wire resistance.

That would only be possible if the device itself can do that. Have you checked the documentation on the device to see if it can do it? If so, there would be a corresponding command that returns all of the readings at once (though obviously it would need to take the measurements themselves one at a time).

My purpose was to only use labview to control the multimeter. Maybe i could have multiple channel lists to input channels which give multiple readings too

Maybe. As I said, you'd need to look at the documentation for the instrument.

There is no documentation on the instrument on labview programming. There is this 'scan list' labview program I got from the web but I do not know how the function works. Does it have the purpose of scanning multiple channels at one time?

You won't find anything for LV programming on the Keithly meter.  What does the mfg documentation say about it's capability?

I'm sure the meter is capable of taking multiple measurements at a time, but how does it report them?  Does it use one USB/GPIB cable or multiple?

Hi Khiam,

When LabVIEW is used to control external instruments such as Keithley 3706 Multimeter, LabVIEW relies on commands supported by the external instruments for functionality.

Documentation of Keithley Multimeter may shows remote commands it supported and if you are lucky, then there might be a command that can scan all the channels and return you the result in an array or some sorts. Otherwise, you would need to create a function in LabVIEW to read each channel individually, put each result into an array and in your program, you would use the function that you wrote.

Hope that this helps.

The documentation I was referring to was the documentation on how to use the instrument, as well as the list of commands. Keithley will not have documentation on LabVIEW drivers.
