However, due to minor differences in each chip, this value may not be completely accurate for each individual board. Usually the amount of difference is so minor as to not make much of a difference, but if desired, the end-user can adjust this constant value by using the following: `scale_constant = internal1.1Ref * 1023 * 1000`
