2.1.1. Recording period
The acquisition on each valid channel is done every millisecond,
For each channel one can choose a sampling period variable from 1 ms to 100 ms
( for Pt100 and Pt1000 3 wires : the period is variable from 2ms to 200ms.)
This period of integration can eliminate noise for high frequency
Example : main noise at 50Hz or engine noise at 1kHz.
For white noise or noise with lower frequency ( lower than recording frequency ) you can
choose a software Butterworth filter
Example :
Recording 9 Channels :
Sampling Period

Ch2

The total time for an acquisition is 200ms, so the minimum period of recording will be 200ms
