hp 428xa conductance

Hi,

 

I am using a Labview program to get data from a HP4284A LCR Precision Meter. Currently the capacity C and D (that is a loss factor I think) are measured. I want to change the measurement so that C and G (the conductance) are measured. It is possible to do that directly at the hp4284a, but I don't know where to define that in the Labview program. Can someone help me?

 

Thanks

              Stefan

Hello,

 

A simple fact, but I'll throw it out there: isn't conductance just

 

 

1 / Resistance

 so you could get your R values, do 1 div R, and get G?

ok, but I don't know, how to measure the resistance, neither. Is D the loss factor and can I calculate R from it?

D is the dissipation factor and the relation between R (or ESR Equivalent Series Resistance ) and D can be  seen in the following article:

I hope it can help you

You are messing up the terms see here

I do not mean to be patronizing. But then using any measure equipment or software it is very important to have at least some knowledge about the theory behind your measurement. You must be able to evaluate your measurement results.

Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)
