The MIT520/2 increases the functionality by permitting test voltage to be set in any 10 V increment from 50 V to 1 kV, then in 25 V steps all the way to 5 kV. The testers measure to 15 Tera-ohms, thereby making them fully suitable for critical installation tests and establishment of reliable base data for new high-capital equipment. Test results are displayed on an electronic digital/analog arc. The case is incredibly rugged and easy to carry, being made of tough polypropylene and achieving an ingress protection rating of IP54. In addition, the model number is marked on both the top and side of the case for ease of identification in stores or vehicles. The instruments have a large easy to read backlit LCD display equally suitable for use in both bright sunlight and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant. In addition, the elapsed time of the test is displayed constantly removing the need for separate timers.
