1. Safety Instructions This operating manual contains information which is necessary to ensure proper operation of the appliance tester. Before commissioning of the appliance tester, thoroughly read and adhere to the instructions contained in this operating manual! Please keep this operating manual for later use! Electrical safety tests of electrical appliances must be carried out by qualified electricians or under their responsibility only.
c In order to detect also short-circuits and body contacts occurring behind the switchon elements (switch, thermostat, relay) of the test sample, the test sample must be switched on. The test sample must be free of external voltage (disconnected from the mains). The device is not intended for measurements in electrical systems! Do not connect any external voltage to the "test socket" and to the built-in jacks or connectors.

BENNING ST 750 A 17. RFID Reader (Optional) RFID is a method for automatic and electronic identification of objects per radio technology. For identification 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.
BENNING ST 750 A - The reading process starts. Wait until the orange LED goes out and an acoustic signal is emitted. The device searches for the ID no. in the internal database. Confirm the queries. If necessary, create the test sample. The data record is displayed. An incorrect reading process will be signalled by two consecutive acoustic signals.
19. Technical Terms Protective measures The test procedure is based on the existing protective measure of the test sample for which the efficacy at the respective accessible conductive has to be proven. For the BENNING ST 750 A Appliance Tester, the following classification has been made: Devices with PE connection (protection class I) The active parts of the device are protected against direct contact.
