The test begins by checking the read range outside the gate (see Fig. points

and

), assuming
the configuration and locality permit it. Start the ISO Inventory command in the ISOStart program
as described in
5.3.2 Reading a Serial Number . If the tag is oriented parallel to the antenna
towards the outside, a read range of 70 to 75 cm should be achieved.
The three tag orientations are checked inside the gate. This corresponds to the lines and
orientations

.
Now slowly move the tag in the vertical and parallel direction with respect to
the antenna along the line

from one side to the other. The tag should always be read.
Then repeat this along the line

in the vertical tag direction transverse to the antenna and on the
line

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
three read orientations.
If one or more „holes“ are detected, check the noise values on the Reader (see
5.3.1 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

20 mV)

Transponder 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, Multiplexer or antenna defective.
