BENNING Benning 050316 ST 725 Appliance Tester

Testing can be done more efficiently and easily. Benning ST 725 – device tester for mobile testing of electrical devices. Usage: Safety testing of electrical equipment according to VDE 0701-0702, DGUV regulation 3 (BGV A3) and BetSichV. The mains operation allows you to check devices with power supplies, such as electronically controlled devices, tools, PCs, copiers and washing machines under operating conditions. Measuring functions: Protective conductor resistance with ≥ 200 mA pulse test current - necessary for oxidised contacts; insulation resistance with 250 V and 500 V test voltage; protective conductor contact current with differential method direct measurement for mains operation and replacement dissipation current for battery operation; active measurement of protective conductor current on 3-phase devices under functional conditions with optional measurement adapter; test fixed and removable 30 mA FI RCD PRCD circuit breakers with measurement of the trigger time; voltage measurement on external earthing contact socket. Features: Automatic testing for class I devices (button 1), class II / III (button 2) and line test (button 3); testing of cable reels, multi-way distributors and device connection cables with low power device plug; reduced test voltage for devices with surge protection; indicator for incorrect test selection and if test device not switched on; battery capacity sufficient for over 2,500 tests; test measurement result with good/bad indicator, VDE threshold values preset. Product features: Memory spaces for 999 test pieces, 3 direct buttons for saving, accessing and printing the readings (printer PT 1 can be connected - see image), mini USB interface and download software for test log creation in MS Excel, direct printing function for test log creation on site via optional BENNING PT 1 printer, extended function test and differential current (maximum 2x 5 minutes), integrated real-time clock for storing the measured values with test date.
