Item name Description
No Numbers are assigned from 1 to 2,048.
The larger the number, the more recent the information.
Time Stamp The Reader/Writer operating time when the diagnostic information was registered.

Diagnostic Result The communications diagnostic result is displayed.
• Good: Stable
• Output level low: Low send power
• Receiving level low: Low receive power
• Noise level high: Excessive ambient noise level
• Signal-Noise ratio low: Low signal-to-noise ratio
• N/A: Communications error
Output Level The send power level to the RF Tag is given between 0 and 10. The higher the value, the better
the conditions. (If the level is 9 or lower, the Reader/Writer will determine that the communication
was unstable.)
Receiving Level The receive power level from the RF Tag to the Reader/Writer is given between 0 and 10. The
higher the value, the better the conditions. (If the level is 9 or lower, the Reader/Writer will
determine that the communication was unstable.)
Noise Level The ambient noise level around the Reader/Writer is given between 0 and 10. The lower the
value, the better the conditions. (If the level is 5 or higher, the Reader/Writer will determine that
the communication was unstable.)
Signal Level The overall level combining Output Level and Receiving Level is given between 0 and 10. The
higher the value, the better the conditions.
Tag ID The Tag ID of the RF Tag for which communication diagnostic was performed is given.
