Quality Assurance/ Quality Control
If the maximum read distance is important for
your application then the antennas have to be
protected/shielded from the interference with a
mounting material firstly and then tuned at
maximum voltage.
In case the maximum read distance is not an
issue the antennas can work properly even at
lower voltage but at a reduced read range.
Method 1
To confirm optimum antenna operation measure the maximum read-write
distance.
1. Take a single tag and position it over the Reader antenna center.
Do not hold the tag antenna coil or tag inner area with you fingers.
Preferably hold the tag edges or use a non metallic carrier to hold
the tag.
2. Measure the maximum read distance in mm and compare with the
value for the same antenna-tag type in the Maximum Read-Write
Distance chart. Refer to this User Manual, Appendix.
3. If the maximum read-write distance is less than the chart value re-
tuning may be necessary. If the antenna is correctly tuned then the
user should determine if the reduction in read-write distance is
acceptable.
Method 2
During an initial tuning procedure measure the maximum voltage using an
Antenna Tuning Probe. Record the voltage value for every antenna in the
ReaderManager software
. To confirm tuning at any time measure the
maximum voltage using the Antenna Tuning Probe and compare with the
recorded results. The voltage values should be identical otherwise the
antenna has to be tuned.
