The Megger MIT1025 DC insulation tester offers preconfigured diagnostic tests including Insulation Resistance (IR), Polarization Index (PI), Dielectric Absorption Ratio (DAR) , Dielectric Discharge (DD), Step Voltage (SV) and ramp test. Ease and speed of use are key points of this instrument. It runs from from rapid charge batteries; a 30min charge will give >60mins run time. Alternatively it will run from a mains supply. It has a large, clear LCD with digital readings and a simulated analog pointer making it easier to observe a circuit's dynamic behaviour. It has enough onboard memory to log data every 5s for 5.5h (with timestamps) and the ability to stream live data or download data to a PC/ laptop via isolated USB. The MIT1025 is designed in accordance with IEEE43:2000 and is ideal for measuring the insulation resistance of armature and field windings in rotating machines rated 1hp (750W) or greater. The standard applies to synchronous, induction and dc machines as well as synchronous condensers. Supplied with a power lead, USB cable, PowerDB Lite software, product information CD and 3 x 3m leadset with large insulated clips.
As lower cost alternatives, the MIT525 (55-5546) with the same test modes and memory but with a lower insulation test voltage or the MIT515 (55-5545) has less test modes and no memory or PC interface.
