When we recorded the data, we needed to find the error noise  in the instruments in order to find the systematic error and eliminate it from our recorded values of both Vsq multi-meters: $V_{sq}$  and the voltage across the photo-diode. The systematic error arises from mean noise voltage due to the amplifier, gain, and multiplier.  In order to do this, every time we changed our gain, we had to drop the voltage across the photo-diode to $0$V and record the systematic error in both multi-meters.
