Megger MIT525/2 Offers
Instrument productivity and accuracy are the focus of the MIT Series. An intuitive user interface ensures no lost time remembering how to use the tester. Simplicity of operation is achieved with two rotary switches and a large backlight display, which enables multiple measurement information to be displayed simultaneously. A graphical quick start guide is provided inside the lid of each model to assist first-time users and has QR code links to the online User Guide. The Advanced models provide an excellent ±5% accuracy up to 1 TΩ at 5000 V, 2 TΩ at 10,000 V, or 3 TΩ at 15,000 V.
One common feature across the whole range is the Megger "no compromise" approach to safety. The Megger level of safety will always go further than simply complying with the relevant safety standards. All Advanced models are safety rated to CAT IV 600 V up to 9842' (3000 m) altitude. The whole range features a dual case design with a tough outer case to protect the tester from knocks and drops, and a fire-retardant inner case. The case IP rating prevents moisture and dust ingress when storing or carrying the instrument. Case lids are removable for improved access to the terminals. A multitude of voltage warnings also help to ensure user safety.
Another common feature is the intuitive colour custom display, with its ability to work in extreme environments and unbeatable viewing angle. Advanced models also include memory storage with time/date stamping of results, logging of data, and recall of results to the screen. A fully isolated USB interface or on-board Bluetooth® interface is used for safe transfer of data to software. With the CertSuite Asset app, you can transfer results while testing, straight onto an Android or iOS mobile device or Windows laptop via USB cable or Bluetooth®.
Features
- RE>Act mode not only measures reabsorption current but also provides an indication to the user of the impact it will have on measurement range and accuracy
- RE>Act removes the possibility to pass insulation that should have been failed, and it can also be used to monitor discharge following a test
- Preconfigured diagnostic tests include:
- Polarisation Index (PI)
- Dielectric Absorption Ratio (DAR)
- Dielectric Discharge (DD)
- Polarisation Depolarisation Current (PDC)
- Stepped Voltage (SV)
- Ramp test
- PI predictor function (PIp) uses the first part of the IR curve to predict the rest at 5 minutes into the test
- Preset voltage ranges are provided in insulation test mode
- Measures up to 10 TΩ
- Up to 6 mA noise rejection
- Negative current handling and user selectable maximum current values of 1 mA, 3 mA, 6 mA
- Hazardous peak voltage detection during IR measurement
- Safety rated up to CAT IV 1000 V to 9842' (3000 m)
- Intuitive colour custom display
- Unique dual-case design for additional user protection
- Double insulated test leads with clamps rated at 3 kV and non-detachable test clips
- Operates from battery or AC mains supply
- Rapid charge Li-ion battery
- Storage with time/date stamping of results, logging of data and recall of results to screen
- Fully isolated USB interface or on-board Bluetooth® interface is used for safe transfer of data to software
Applications
- During manufacture, as part of quality inspection or safety checking prior to shipment
- Prior to product/asset shipment to provide benchmark measurements
- On site inspection, comparing to benchmark results, to ensure everything is good before installation
- Checking after installation of a new asset
- During maintenance to drive predictive maintenance
- Following repair prior to powering up
