High-voltage tester MI 3121H SMARTEC

insulation resistance and continuitycableinstallation

The MI 3121H Smartec 2,5 kV Insulation / Continuity is the portable measuring instrument for complete diagnostic testing of insulation and continuity measurements. MEASURING FUNCTIONS • Insulation resistance with DC voltage up to 2.5 kV • Diagnostic test (PI, DAR calculation) • Continuity of PE conductors with 200 mA test current and polarity change • Continuity of PE conductors with 7 mA test current (continuous measurement) without RCD tripping • TRMS voltage and frequency KEY FEATURES • High measuring range: up to 100 GΩ with test voltage from 100 to 2500 V • Insulation diagnostics: PI and DAR calculation for determining if the insulation damaged or contaminated • Guard test terminal: for elimination of potential surface leakage currents • Polarity swap: automatic polarity reversal on continuity test • Analogue scale: measuring results are displayed in numeric and analogue representation. • Custom limits: if limits are set on insulation or continuity function then large green and red lights of the LEDs will indicate a PASS or FAIL evaluation of test result • Safe: suited for testing on CAT IV installations • Built-in charger & rechargeable batteries: instrument has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries. Memory: two level memory structure for saving of test results and parameters • Downloadable: downloads via RS232 or USB cable directly to the PC with the help of the PC software EuroLink PRO • Easy to use: large bright LCD display and large buttons enable easy handling of the instrument (even while wearing gloves) • Magnetic holder: magnet for fixing instrument on metal surfaces enables hands-free operation
