Key Features of the Megger MIT525
- Multiple Test Modes: Perform a range of diagnostic tests, including insulation resistance (IR), dielectric absorption ratio (DAR), polarisation index (PI), dielectric discharge (DD), step voltage (SV), and ramp tests.
- Test Voltages Up to 5kV: Choose from preset ranges of 250V, 500V, 1000V, 2.5kV, or 5kV, or program your own voltage from 100V to 5kV in adjustable steps.
- High Resistance Measurement: Accurately measures resistances up to 10 TΩ, making it suitable for demanding environments.
- Advanced Battery Technology: Equipped with rapid-charge Li-Ion batteries, offering over 60 minutes of testing after just a 30-minute charge. Can also operate directly from AC mains power when needed.
- Onboard Memory: Save test results with time and date stamping, and recall them on-screen or transfer data securely to a PC using the USB interface. Compatible with Megger’s PowerDB Lite, Advanced, and Pro software for seamless data management.
- Enhanced Safety: Designed with operator safety in mind, the MIT525 features a CAT IV 600V safety rating and 12kV-rated test leads. Its dual case design includes a tough outer shell for impact protection and an inner fire-retardant case for extra durability.
- Intuitive Interface: A large backlit LCD display and two rotary switches make operation simple and efficient. Inside the lid, a quick start guide ensures users can get started quickly, even for first-time operators.
- Additional Features: Includes a dedicated voltmeter function (30V to 660V), capacitance measurement (10nF to 25 µF), and high noise immunity (3mA rejection).
