Geiger Tag Utility
The Geiger Tag utility is designed to assist you in finding the location of a particular tag, or one of a
group of tags. It does this by measuring the returning signal strength (RSSI) from the tag, and
displaying this information on the screen, along with an audible and vibratory queue. As you pass
the reader near a tag, the RSSI increases, and you will see, hear, and feel the change.
To start the Geiger Tag search, either hold the pistol-grip trigger button, or click once on the green
Start Search button. The reader continues to read tags until you release the trigger or click the Stop
button. Click the red Close box at the top-right corner to return to the main screen.
The Geiger will show the tag’s signal
strength. Use the Start Search button
(or pistol-grip trigger) to start the search.
When a tag is read, its EPC is displayed
on the screen, along with graphical and
numeric readouts of the tag’s return
signal strength.
Having the Geiger react to every tag it sees can
quickly become overwhelming. Use the yellow
Mask button at the top-left corner to indicate
which tag or tags you are interested in finding
(see the Tag Mask section). Narrowing the
search down with a tag mask can make the
Geiger utility much more effective.
If a tag corresponds to an Asset that has
already been defined, its image and
associated barcode are also displayed.
