The actual value of a data point can be calculated with
the following formula:
(Decimal value of hex data/AD Factor) * vertical scale.
Note: AD Factor is fixed as 25. The vertical scale is
returned with the acquisition settings that precede the
raw data.
For example if the raw data for a point is 001C (=28
decimal) then,
(28/25) x 0.5 = 0.56V
