Data source

The charts, which can be seen on the screen can be created basing on data directly transmitted from the registers (also currently - in „on-line” mode). In this case, in order to view data from the registers' memory a connection to the register must be set. As data source Recorder should be selected.If data are viewed directly from the register an On-line mode can be chosen. In this case the charts on the screen are currently (minute by minute) updated as the data are registered in the register and transmitted to the computer. As data source On line should be chosen. The charts also can be created from data stored on the disc or other data archives. In this case the connection is not necessary, but the data must have been stored and exist on the disc. (More about data archiving in chapt. )If Disk is selected as data source a disk location from where the data will be read should additionally be selected. The Default directory is the LOGGER program subdirectory proceeded by "/Data" (usually c:/ Program Files/LOGGER/Data or c:/LOGGER/Data).Floppy disk A means main directory of a floppy disk placed in A drive.Any directory selection enables randomly choosing any location where data is stored (including flash disks – pen drives or CF cards).Data source can be chosen separately for each opened data window. Hence it is possible to view and compare the data diagrams made directly ``from datalogger's memory'' and archivised on the disc at a time. (see fig. 5.1)Data source is signalled at the right hand of the status bar:

HD - data from disk archives
FD - data from floppy
REJ - data directly from AR datalogger
