“Graphics” Menu:
With this menu you have the ability to graphically display a tag’s field strength. This can
be useful for estimating the possible ranges i.e. to set the read zones.
The parameters from the Configuration Page (antennas, output power, scan-interval, etc.)
are to be used as settings.
Pressing the DO SCAN button triggers a scan. If tags are located in the zone, a list of
these tags will be displayed. Clicking on one or more tags transfers those Tag IDs to the
next field. Next, click on SET SELECTED TAGS.
Clicking on START APPLETS opens a window for each activated antenna (see
“Configuration”). In this window, the field strength progression is graphically displayed for
each tag that was selected. After every scan, the measured field strength from the tag
signal is entered into the diagram.
This feature allows you to estimate the size of the read zone at the given output power,
i.e. to roughly estimate the distance of the tag.
