If one or more „holes“ are detected, check the noise values on the Reader (see

Noise Level
).
The following may result in faulty readings:
•
Antenna improperly installed (orientation, antenna distance, check cabling)
•
Metal near the antennas is detuning or interfering with them.
•
The antennas are not properly tuned.
•
Noise level too high (Vmax – Vmin
≥
20 mV)
•
Transponder too insensitive, detuned or defective
•
Reader improperly configured (transmitting power, transponder type, modulation, transponder
parameters, etc.).
•
A cable is defect or has a weak contact.
•
Reader, multiplexer or antenna defect.
