If we want to acquire the data with slow speed, we can choose the always slow storage option. The data will be stored at intervals, which are set with static/reduced rate. In our case, this is set to 0,1 seconds. Thus much less disk space will be used for storage.

Even though storage is set to slow, DEWESoft will still acquire the data at full speed, calculate the minimum, maximum, average and RMS for this time interval and store only those values.

 

Let's store some data and take a look how the data appears in the recorder. This is what the data looks like at full rate in Acquisition mode.

 

And now let's switch to analyse mode. The data will be shown as the envelope of the original signal since the full rate rate is no longer available, merely the 0,1 second values. We can also switch to average or RMS modes in the recorder setup to see those two parameters.

 

The recorder below shows the RMS of the signal. We can judge from the average, RMS and min/max values what the original signal could be. For example if there is a big maximum and the average value did not grow, we can deduce that there was a short spike in that channel.
