No of channels×2×24×3600
(! Note: Calculation of the number of channels: The program divides the
number of channels into 5 gears ,that is, 4, 8, 16. When the number of
instrumentation channels falls between the two gears, the larger number is
used as the number of channels. For example, the number of instrument
channels is 12-channel, and the number of channels is calculated with 16 in
the formula.
