Appliance Tester BENNING ST 720
Mains-operated and battery-operated Appliance Tester for mobile testing of electrical devices
- testing in compliance with DIN VDE 0701-0702 (EN 62638), BGV A3, BetrSichV (German Health and Safety at Work Regulations), ÖVE/ÖNORM E 8701, NEN 3140
- quick - testing within a few seconds
- all-in-one - appliance tester and RCD tester in one single device
- unique - testing of single-phase and three-phase devices under operating conditions
Testing of devices with mains voltage-dependent switching elements/mains-supply units/relays such as controlled devices/tools, devices of information and communication technology as well as of devices which can be tested completely with mains voltage only.
In mains operating mode, the protective conductor current/contact current is measured by means of the required differential current/direct measurement method.
Features BENNING ST 720
- mains operating mode for tests under operating conditions
- battery operating mode for mobile testing
- automatic testing procedure for devices of class I (key 1), class II/III (key 2) and line test (key 1)
- reduction of the ISO testing voltage for devices with overvoltage arresters
- testing of RCDs with 30 mA
- indication of correct function key in case of incorrect operation, overload and if the test sample is not switched on
- sufficient battery capacity for more than 2,500 test samples
- limiting values preset in compliance with DIN VDE standard
- measuring result with “pass/fail” information
