Data format
Measured/computed data is saved in binary format.
Data size
Data size can be calculated using the following equations.
Measured data: 2 bytes / 1 data
Computed data: 4 bytes / 1 data
Header: 576 + 64 x (number of measurement channels + number of computation channels) bytes
Data size = 576 + 64 x (number of measurement channels + number of computation channels) +
(number of measurement channels x 2 + number of computation channels x 4 + 6) x specified
data length
For instance, if the number of channels is 10, number of computation channels is 5 and specified
data length is 5k, the data size can be calculated as follows.
Data size = 576 + 64 x (10 + 5) + ((10 x 2 + 5 x 4) + 6) x 5k = 231,536 bytes
