Voltage tester MI 3121 SMARTEC

insulationcontinuityinsulation resistance and continuity

The MI 3121 SMARTEC Insulation / Continuity is a tester for dead testing of electrical installations. MEASURING FUNCTIONS • Insulation resistance with DC voltage • Continuity of PE conductors with 200 mA test current with polarity change • Continuity of PE conductors with 7 mA test current (continuous measurement) without RCD tripping • TRMS voltage and frequency KEY FEATURES • Insulation range: wide range of insulation test voltages from 50 V to 1000 V, measuring range up to 30 GΩ • Analogue scale and digital LCD: measuring results are displayed both in numeric and analogue representation • Downloadable: downloads via RS232 or USB cable directly to the PC with the help of the optional software • Upgradeable: if changes occur to the regulations upgrades can be made to the firmware to keep the instrument up to date • Polarity swap: automatic polarity reversal on continuity test • Built-in charger & rechargeable batteries: instrument has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries • 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 • 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
