Electrical Installation Safety SINGLE-FUNCTIONAL TESTERS


MI 3121 SMARTECInsulation / Continuity


The MI 3121 SMARTEC Insulation / Continuity is a new generation tester for dead testing of electrical installations. With both an analogue and digital representation of the results, the instrument ensures accurate measurements up to 2000 Ω on continuity and up to 30 GΩ on insulation function. Configurable limits enable a PASS / FAIL evaluation of test results, which is accompanied with the bright red and green indicator lights for comfortable use even in the dark conditions. The MI 3121 is equipped with a built-in charger and has a magnetic holder in order to free up hands for testing. All the results can be quickly saved on the instrument and then downloaded via the optional A 1291 EuroLink PRO or A 1290 EuroLink PRO Plus software for evaluation and professional report generation after testing. The MI 3121 SMARTEC Insulation / Continuity performs continuity, insulation AC voltage and frequency measurement tests.


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 measure- ment) without RCD tripping; • TRMS voltage and frequency.


KEY FEATURES:


• Insulation range: wide range of insu- lation 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 re- versal on continuity test.


• Built-in charger & rechargeable bat- teries: instrument has a built-in charg- ing 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.
