In order to find the Boltzmann constant and the charge of the electron, we had to perform the Johnson Noise Experiment and the Shot Noise Experiment. We performed the Johnson Noise Experiment in order to find the Boltzman Constant: $1.38064852 × 10^{-23} \textrm{ m}^2 \textrm{ kg} \textrm{ s}^{-2} \textrm{ K}^{-1}$. We performed the Shot Noise Experiment in order to find the charge of an electron: 1.60217662 × 10-19 coulombs.
When we recorded the data, we needed to find the error in the instruments in order to find the systematic error and eliminate it from our recorded values of both Vsq and the voltage across the photo-diode. In order to do this, every time we changed our gain, we had to drop the voltage across the photo-diode to 0V and record the systematic error in both multi-meters.
