Professional 2,5 kV Insulation / Continuity tester The MI 3121H Smartec 2,5 kV Insulation / Continuity is the portable measuring instrument for complete diagnostic testing of insulation and continuity measurements. Due to insulation resistance measurement with the test voltages up to 2.5 kV (measuring range is up to 100 GΩ) and calculation of PI and DAR indexes the instrument is ideally suited for testing insulation of cable lines, current and voltage transformers, electric motors, etc. MEASURING FUNCTIONS: • Insulation resistance up to 100 GΩ with DC voltage up to 2.5 kV; • 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: Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) calculation. • Analog scale: measuring results are displayed in numeric and analogue representation. • Guard test terminal: for elimination of potential surface leakage currents. • Polarity swap: automatic polarity reversal on continuity test. • 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. • Magnetic holder: magnet for fixing instrument on metal surfaces enables handsfree operation. • 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). APPLICATION: • Insulation resistance of transformers, motors, cables, machines, etc.; • Testing on CAT IV installations (distribution side of installations, industrial plants etc); • Observation of insulation trends; • PE conductors continuity testing; • Main and supplementary PE connections testing; • Troubleshooting (connectivity, polarity).
