Calibrating a microphone using SVL Calibrate Microphone

Hi all,

 

So I'm working on a VI that dislays sound pressure level. 

 

From the other discussions,  it says that SPL can't be measured unless you have a calibrated microphone and a known amplification path.  

So basically LabVIEW has this SVL Calibrate Microphone (DAQmx) to calibrate the mic. However, I tried to use it but I've got no result.

I have an ECM 8000 condenser microphone and I'm using a USB-6215 DAQ.

 

How do I perform this calibration?

First, what do you mean that you "got no result"? No output from the mic? incorrect results?

When I run the SVL Calibrate Microphone, there is no output from the calibrated sensor sensitivity?

 

How do I connect my micropone from the DAQ, do I select it as input or select as output. How do I calibrate it?
