Overview
The Metrel 3121 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 2000Ω 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. The Metrel 3121 Insulation / Continuity performs continuity, insulation AC voltage and frequency measurement tests.
Applications
- Domestic dead circuit testing
- Industrial dead circuit testing
- Telecommunication systems testing
- Resistance measurements
Tests
- 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
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.
Insulation range: wide range of insulation test voltages from 50 V to 1000 V, maesuring range up to 30 GΩ.
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)
