Noise Measurement

You can check whether noise that affects communications with RF Tags exists in the surroundings where the
Antenna and Reader/Writer are installed.
When a noise measurement command is sent from the PLC, the noise strength received by the Antenna is
output in a value from 00 to 63.
To start in Noise Level Measurement Mode, set the mode switch to 3, and then start the Unit. The noise
strength will be displayed in five levels on the data display. It can be checked directly from the FL Remote ID.
Refer to NOISE MEASUREMENT for details of the noise measurement command.
