The Megger MIT230 is one of the most compact insulation testers available on the market today. Its display offers a combination of digital readout and analog display, using Megger’s patented DART technology. The tester therefore includes the benefits of an LCD display such as clear, accurate measurement and precise readings, with an analog pointer response for evaluating circuit charge and discharge characteristics.
The MIT230 housing is in tough ABS, designed to withstand the rigors of hard day-to-day use, and is small enough to drop into your pocket or tool bag.
Battery requirements are 6 AA batteries of either standard alkaline or nickel metal hydride (NiMH) rechargeable type. A low battery warning indicator gives advanced warning of exhausted batteries.
Automatic continuity testing is performed at 200 mA to ensure compliance with international requirements. The convenient auto-start feature means there is no need to press the test button to begin the test -both hands can be used to hold the test lead probes.
The MIT230 will measure up to 100 ohms on continuity, with 0-10 ohms using 200 mA so meeting international electrical testing requirements. Lead null is possible up to 9.99 ohms of test lead resistance, providing the ability to null fused, extended or standard test leads.
A buzzer provides a means of rapid cable testing and circuit continuity identification, with voltage protection should you accidentally touch a live circuit. The buzzer operates at a 2 ohm threshold.
The MIT230 supports insulation testing at 250 V, 500 V, and 1000 V. Auto discharge ensures all circuits under test are safely discharged after testing. The 1000 V insulation test range furthermore provides a high voltage warning prior to test voltage being applied.
The MIT230 Tester is designed with safety as its primary objective. There are in-built safety checks to warn of inadvertent connection to a hazardous live supply on all ranges. The MIT230 either meets or exceeds the requirements of safety directive IEC 61010 and EN 61557 for insulation and continuity testing.
A built-in voltmeter is automatically activated and displays the system voltage when the MIT230 is connected to a circuit with an AC or DC voltage greater than 25 V.
Circuits in excess of 25 V will generate a voltage warning as above. The instrument will inhibit testing on circuits over 50 V on both continuity and insulation test ranges, protecting the operator and the instrument from injury or damage.
