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.
