Product catalog summary

Overview: The MI 3121 Insulation/Continuity Tester is designed for verification, maintenance, and periodic testing of electrical installations. It is suitable for testing PE conductors, main and supplementary PE connections, troubleshooting connectivity and polarity, and measuring insulation resistance. It is applicable for CAT IV installations, including distribution sides and industrial plants.

Standards: The instrument complies with IEC/EN 60364, VDE 100, BS 7671 17th edition, and CEI 64.8. It is also applicable under IEC/EN 61557 Parts 1, 2, 10, IEC/EN 61010-1, and IEC/EN 61326.

Main Features: The tester features a large LCD display with a bargraph and backlight, a high measuring range up to 30 GΩ with test voltages from 50 V to 1000 V, and fast continuity tests with automatic polarity reversal. It includes voltage and frequency measurements, preprogrammed limits, and PASS/FAIL evaluation with visual indicators. It is equipped with a magnetic holder for hands-free operation, a built-in battery charger, and a two-level memory structure for saving test results. It supports data transfer via USB and RS232 ports and is compatible with EuroLink PRO and EuroLink PRO Plus PC software packages.

Technical Specifications:

Insulation Resistance: Test voltages range from 50 V DC to 1000 V DC, with a measuring range up to 30 GΩ. Accuracy varies with the range, from ±5% to indicative values.
Continuity: Measuring range from 0.16 Ω to 1999 Ω with a minimum current of 200 mA. Automatic polarity reversal is included.
Voltage and Frequency: Voltage measuring range is 0 to 550 V with true RMS results. Frequency range is 0 Hz to 500 Hz.

General Data: The device is powered by six 1.5 V batteries or rechargeable AA batteries, with a typical battery life of 13 hours. It is rated for overvoltage categories CAT III 600 V and CAT IV 300 V, with double insulation and IP 40 protection. The device has a memory capacity for 1900 measurements and weighs 0.80 kg without batteries.

Ordering Information: The standard set includes the MI 3121 tester, test cables, test tips, alligator clips, a power supply adapter, and instructional materials. Optional accessories include various test leads, a fast battery charger, magnetic contact probe, and carrying bags.
