Labview does not read the amplitude of waveform correctly for TDS 2014 scope

Hi, 

I downloaded drivers for tektronics TDS 2014 oscilloscope from NI website (http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=047216EC20B66FABE0440003BA7CCD71#seeBelow ).  I am trying to collect waveform from the oscilloscope. I am able to talk to the oscilloscope and see the waveform on my computer. However, the waveform displayed has 10 times higher amplitude than the actual waveform. I have set the Probe attenuation to unity and I am not sure what makes this change in the waveform. 

The vi I have been using is attached here.

Thanks for your help!
