Or
Recording Time in Seconds = Total Installed Memory in Bytes/(( No. of
Channels) * (Sampling Rate) * 8 Bytes * 1.2)
For example if you enabled 6 channels, the sampling rate is 100 Hz with 4GB
memory installed:
Recording Time in Seconds = 4GB/(6*100*8*1.2) =
4*1024*1024*1024/(6*100*8*1.2) = 745654 sec (= 207 hours)
When data compression is used, the storage space will be doubled. The spectrum
dynamic range of compressed data will be reduced to about 100dB. If the storage
space and downloading time is not an issue for your application, then data
compression should not be used.
The figure below illustrates the difference between the concepts of Display -
Run/Hold, Time Stream - Record/Stop and Signal - Save. The Display
mode is independent of the Record or Save functions. When you change the
Display mode between Run and Hold it has no effect on the Save or Record
functions. That means that time streams can continue to be recorded when the
display is in Hold mode.
