The test begins by checking the read range outside the gate (see Fig. points
c
and
d
), assuming
the configuration and locality permit it. Start the ISO Inventory command in the ISOStart program
as described in
4.4.2 Reading a Serial Number
. If the tag is oriented parallel to the antenna
towards the outside, a read range of 65 to 75 cm should be achieved.
The three tag orientations are checked inside the gate. This corresponds to the lines and
orientations
efg
.
Now slowly move the tag in the vertical and parallel direction with respect to
the antenna along the line
e
from one side to the other. The tag should always be read.
Then repeat this along the line
f
in the vertical tag direction transverse to the antenna and on the
line
g
in the horizontal tag orientation. Here again the tag should always be read.
The tag should be read within the gate when moving horizontally through the gate in all 3
read orientations.
If one or more „holes“ are detected, check the noise values on the Reader (see
4.4.1 Checking the
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
≥
30 mV)
•
Tag too insensitive, detuned or defective
•
Reader improperly configured (transmitting power, transponder type, modulation, transponder
parameters, etc.).
•
A cable is defective or has a poor contact.
•
Reader, Power Splitter or antenna defective.
