46. zed due to manufacturing tolerances the actual values Ts1 and Ts2 may not be the same This means that the data packets will arrive to datalogger with seemingly irregular intervals The datalogger has an internal quartz clock and associates each packet with the instant of time corresponding to its reception with a resolution of 0 1 s When you use the Dataget program on your PC to download data from the datalogger it is requested to specify the desired final sampling time Tsf used to re sync all the samples FE01 02 comes with a default value for Ts of min The default value for Tsf is 30 min with these values the data are over sampled by a 10 1 ratio Dataget generates an ASCII file where each line corresponds in this case to time references multiple of 30 minutes and contains the interpolated average values of all the data sent by the nodes within this time interval In other words the row corresponding for example at the time reference of 90 min will contain in each column the value of the physical quantity averaged between all the values received from the datalogger in the time range 75 105 min the average will be over 10 values for what previously assumed The values of the sampling times of the nodes and the final sampling time Tsf can be modified by the user according to the type of the measurement You should choose for Tsf the highest possible value making sure that measured signals would not vary significantly during this time Be
