The device triggers alarms as soon as the set threshold (consisting of “Measurement
Alarm” 1/2 “Threshold”) is exceeded in the read process.
The device can use the following value as a source for the alarm:
•
RSSI value (transponder in the detection range)
The “Time the transponder is in the detection range [ms]” specifies for how many ms
the transponder is in the detection range. If this time is less than the set threshold, the
device outputs an alarm.
The triggered alarm remains active in mode "2 = RSSI" until the condition is fulfilled
again. If the “Transponder in Range time” condition was selected, the alarm is active
until a new transponder is situated in the detection range.
