Capetti Elettronica WINECAP WSD12-2DI User Manual

1. Description.
The WSD12-2DI is a datalogger with two input channels to acquire pulses from clean contacts or open-collector, from energy meters,
fluid meters, etc. inputs, with storage functionality of samples acquired.
Counting is continuously performed on input channels and is partially considered on the configurable sampling period. In case,
counting can be set as aggregate and scalable.
Data are wireless transmitted and internally stored.
2. Sampling.
In normal mode, the measure acquired is related to pulses counted in the programmed sampling interval.
At the end of each interval, the counted value, multiplied by the energy weight, is transmitted to the basestation, and internally
saved.
After which, the counter is reset, and a new integration cycle starts.
In cumulative mode, count is maintained and is automatically updated to new value at each measure interval.
Value can reach overflow; in case, counter resets and automatically starts again when reaches the maximum value of 65,535 pulses.
Sampling time is selectable and adjustable by radio but is recommended to set a time and maintain it fixed for the complete measure
harvest to guarantee values and intervals homogeneity.
To perform an analysis in an established period, a summation of whole contributions coming from each interval is needed.
In normal mode, performing a graphical analysis of samples, is easily possible to compare higher impact pulse periods with lower
impact ones, obtaining the measure timing profile, locating peaks and lowest periods.
To obtain the total amount in a period, a sum of samples acquired in the period can be performed.
NOTE:
if the basestation analog output is coupled to the datalogger's meter channels, the expected output signal will be a tier where
each level represents the recorded energy in the previous period
A punctual evaluation of weight/pulse/sampling interval/maximum output signal amplitude parameters is necessary to obtain best
dynamic results and avoid signal saturation.
With the same sampling interval, and consider the in-use amplitude scale, a wave integral calculation is possible, obtaining the energy
counted on a longer period.
