keithley 2010 drivers and VI

[buchaiah]

 Sir/madam, I need a Labview VI for interfacing Keithley 2010 multimeter and want to measure the voltage with time. I have checked in NI website for drivers and VI but for 2010 is not there. There are VI for 2000 and 2001.
Please, could you send any VI related to Keithley 2010 interfacing?
waiting for your fast reply
Thank you...

The most accurate way to do it is to use the internal triggering of the meter.  It will take a measurement, wait N ms, take a measurement, wait N ms, and repeat that as many time as you request.  Then you read back all the data at once.  Look at the "Multi Read Example.vi" in the driver.  

Another way is to fecth a single measurement, use the PC time to calculate the delta between measurements and plot that.  Its far less accurate.  It all depends what you really need (which you haven't described). 

- Measurements every 1ms for 10s?

- Measurements every 10s for 1 day?

- Measurements every 2 weeks for 10 years?

The approach would probably be different in each case.

You could try something like this.  It might be better to just abandon the old driver (LabVIEW 6.0!) all together use VISA and the instrument command throughout.   But try something like this..
