Aplification calculation.

Using Runs 6 & 7 for the unamplified signal (on 0.1) scale and runs 8 & 9 for the amplified (10 V scale). 
Amplification = mean([Testplt9.Vsamp_mean Testplt8.Vsamp_mean])/mean([Testplt6.Vsamp_mean Testplt7.Vsamp_mean]) = 1277.557
The relative error for runs 6 & 7 is 4.6242e-04
The relative error for runs 8 & 9 is  2.2082e-06
