BENNING ST 750 A
17. RFID Reader (Optional)
RFIDisamethodforautomaticandelectronicidenticationofobjectsperradiotechnology. For
identicationoftheobject,thedatacanbereadoutbywirelesstechnologyviaaradiofrequency
channel. A marked object only sends its data, if the reader calls the transponder. An RFID system
consists of two components: a transponder and a reader. The transponder (in the following referred
toas"tag")istheactualdatacarrier.
It is possible to read it and to write on it without any contact by means of radio technology. The tag
stores data of the tag and of the connected object. The reader consists of a reader/writer unit with
antenna. The reader reads data of the tag and writes data to the tag. The reader is provided with a
USB 2.0 interface to transmit the received data to the BENNING ST 750 A Appliance Tester.
For installation of the tags, it has to be observed that metallic surfaces strongly interfere with the
radio connection. Therefore, do not install them directly onto metal or a metal housing. Data ex-
change between reader and transponder does not require direct contact (even not a visual contact).
Barcode labels can be exchanged by means of RFID transponders. The device communicates with
passive HF transponders with 13.56 MHz. The reading process is started by pressing a button. If
atransponderhasbeenidentied, this is conrmed by an acoustic signal.Itisnotnecessaryto
conguratetheRFIDreader.

In case of faults, switch off the appliance tester. Remove the RFID reader, reconnect it
and then switch on the appliance tester.

17.2 Operating the RFID Reader
The RFID reader can be used in combination with the following device groups: BENNING ST 750 A

For reading / writing processes, wait until the orange LED goes out.
An incorrect writing process will be signalled by two consecutive acoustic
signals. Repeat the process!
Commissioning:
- Switch the BENNING ST 750 A Appliance Tester OFF.
- Connect the RFID reader to the BENNING ST 750 A Appliance Tester (USB-A jack).
- Switch the BENNING ST 750 A Appliance Tester ON.
- MakesurethattheRFIDlamp("Power")switcheson.
Writing onto the transponder: (inventory data)
- Create the inventory data of a test sample in an internal database or select an existing test
sample (ID no.).
- <Select> <Save> and confirm the queries.
- Message: "Do you want to save the data record on the RFID transponder?". Confirm with
<Yes>.
- The orange LED of the RFID reader flashes.
- Hold the scanning window of the RFID reader over the RFID transponder and press the button
on the bottom of the scanner.
- The writing process starts. Wait until the orange LED goes out and an acoustic signal is emitted.
- The data are saved on the RFID transponder.
An incorrect writing process will be signalled by two consecutive acoustic signals. Repeat
the process!
Writing onto the transponder: (measured values)
- Carry out the test.
- When the test result is displayed, select <Save>.
- Confirm the queries.
- Message: "Do you want to save the data record on the RFID transponder?". Confirm with
<Yes>.
- The orange LED of the RFID reader flashes.
- Hold the scanning window of the RFID reader over the RFID transponder and press the button
on the bottom of the scanner.
- The writing process starts. Wait until the orange LED goes out and an acoustic signal is emitted.
- The data are saved on the RFID transponder.
An incorrect writing process will be signalled by two consecutive acoustic signals. Repeat
the process!
Reading the ID no. from the transponder and searching in internal database:
- Hold the scanning window of the RFID reader over the RFID transponder and press the button
on the bottom of the scanner.
