HEAT INSULATION The Megger MIT410 Industrial Insulation and Continuity Tester has been designed for elctrical testing by utilites, industrial, commercial and domestic electricians. The Megger MIT410 offers fantastic functionality with simplified operation and increased safety. Insulation testing up to 1000V and continuity testing at 200mA or 20mA is provided with TRMS & DC voltage measurement and a combined analogue and dual digital display. The MIT410 has additional features such as polaristaion index, dielectric absorption ratio functions, capacitance measurement and a higher insulation range increasing the suitability for service, repair and maintenance applications. Insulation Testing Impressive 50V - 1000V insulation test voltages available. Test Lock to lock insulation test on continuously. Actual test voltage is displayed on the smaller digital readout. Insulation result on the larger digital display. Analogue arc display to replicate the response of a moving coil display. Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) functions Insulation testing from 5GΩ to 100GΩ. High quality flexible silicone test leads prevent measurement errors on higher GΩ ranges. Test inhibit prevents insulation testing if voltages in excess of 50V are detected. Insulation buzzer can be set to buzz if the insulation resistance is above a preset limit. Continuity Testing Auto test on circuit contact. 200mA or 20mA continuity test currents are available. 20mA will considerably increase battery life. Lead resistance compensation (null) operates up to 9.99Ω of resistance. Buzzer selected by simple push button. Adjustable continuity buzzer limit alarm from 1Ω to 20Ω in 5 steps. kΩ range extends resistance measurement to 1MΩ. The Megger MIT410 use a patented analogue arc display which shows essential charge and discharge characteristics not visible on a digital display. The single pointer needle response mimics a moving coil meter and the logarithmic display is used for improved low insulation value measurements. A dual digital display is also employed by the MIT insulation tester. The large main digital readout offers good visibility for all main  measurements while the second digital display is used for additional data such as insulation test voltage, insualtion leakage current, frequency and test mode. The MIT 410 is designed to be exceptionally safe to use with fast detecting circuitry to prevent damage if accidentally connected to live circuits or across phases. In addition the Megger insualtion & continuity tester has a default display of live circuit voltages on all ranges with detection and inhibit functions even if the protection fuse has failed. The unit meets the international requirements of IEC1010-2 and EN61557 with a CAT IV 600V rating.
