Description

Metrel MI 3121H SMARTEC 2.5kV 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 suited for testing insulation of cable lines, current and voltage transformers, electric motors, etc.

Due to configurable limits the instrument enables PASS / FAIL evaluation of test results which is accompanied with bright green or red light of LEDs. Additional features include magnetic holder for fixing the tester on the metal surface and built-in charger. The MI 3121H is compatible with EuroLink PRO software which enables downloading and analysis of test results and creation of professional test reports.

MI 3121H (Standard Set) Comes Supplied With:

Instrument Smartec Insulation / Continuity
Soft hand strap
Test lead, 2 x 1.5 m
Test probe, 2 pcs (black, red)
Crocodile clip, 2 pcs (black, red)
Power supply adapter + 6 NiMH rechargeable batteries, type AA
Instruction manual on CD
Short instruction manual
Handbook on CD
Calibration certificate

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.

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.
