The ramp function gradually increases voltage up to a selected level while graphing current vs. voltage. Graphs can then be downloaded, or streamed real time (Must purchase optional software). Graphs can then be compared to example curves in IEEE 95-2002 to reveal a variety of faults difficult to detect otherwise. Small defects can be easily detected without risking the sudden large voltage increments produced by a Step Voltage test. Monitoring the developing graph during test enables the operator to terminate prior to breakdown, thereby reducing the possibility of damage to already flawed insulation. This unit is particularly informative on polyester, asphalt and epoxy-mica insulations. They can also test voltage suppression devices. Please check our Huge Inventory with savings of up to 8.

A built-in integral timer starts automatically at the beginning of a test, and displays in minutes and seconds. At the end of any test, capacitive loads are automatically discharged and the decaying voltage displayed. The timer enables the performance of an automatic IR test with the MIT510/2, while the MIT520/2 and MIT1020/2 add the capability of preprogrammed DAR, PI, SV and DD. The MIT520/2 and MIT1020/2 include a selectable breakdown or burn mode and an alarm mode, which allows the operator to preset a specific resistance level. The unit will beep until the limit is exceeded. The controls of the instruments are clear and unambiguous, and a “quick start” guide is included in the lid, eliminating the need to carry manuals to site locations. Redundant safety features make the instruments.

Never Used! 2x Megger Insulation Resistance & Continuity Testers. 1x MIT300 and 1x MIT410/2. Bought when planning to become self employed electrician but never followed through so now have no need for them. They are both in perfect working order. Would be ideal for any electrician but especially for one looking to start their own business. I can sell them separately or together. MIT300-£400, MIT410/2-£475 or both for £850. Absolute bargain!
