HEAT INSULATION The new Megger MIT400 series insulation and continuity testers has been designed for electrical testing by the utilities, industrial, commercial and domestic electricians. The wide range of features also makes the MIT400 series ideal for the maintenance and service/repair engineer. They replace the well-established BM400 insulation tester range, given greater functionality with simplified operation. CATIV 600V applications Insulation testing to 1000V and to 200GΩ TRMS & DC Voltage measurement Continuity testing at 200mA down to 0.01Ω Analogue and dual digital display Insulation & continuity limit alarms PI/DAR and Timer function Test result storage  Insulation Testing Test voltages 250V to 1000V insulation test voltages available Test Lock locks insulation test on continuously. Actual test voltage is displayed on the smaller digital readout. The 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 10GΩ to 200GΩ High quality flexible silicone test leads prevent measurement errors on higher GΩ ranges. Test inhibit prevents testing if voltages in excess of 50 V 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. 20 mA test current will considerably increase battery life. Lead null - Lead resistance compensation (NULL) operates up to 9 Ω of resistance. Buzzer ON-OFF selected by simple push button. Continuity buzzer limit alarm is adjustable from 1 Ω to 20 Ω in 5 steps. Analogue arc display Full display width analogue arc. Patented arc display shows charge and discharge characteristics not visible on a digital display. Single pointer “needle” response is similar to a moving coil meter.
