Fluke HANDYISO LEM Professional Earth/Ground Tester

Insulation Tester NORMA Handy - a handy insulation measuring device with universal application possibilities, including RISO measurements with 100V (up to 20GOhm, very important for telecommunication applications), 250V, and 500V (standard measurement voltage for electrical installations with nominal mains voltages of 500V). Low-resistance measurements are performed pursuant to IEC 61557, or DIN VDE 0413 with a short-circuit current of >200mA, providing for standard-complying measurements regarding low-resistance of both non-fused earthed conductor connections and potential equalization. Testing of electrical loads subsequent to maintenance or extension according to DIN VDE 0701, and repeat tests according to DIN VDE 0702 is also possible: The user can directly read both RPE and RISO values.
