절연저항계 MIT 410 (영국)


	DESCRIPTION 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, greater application range and increased safety. The range The range consists of five instruments: MIT400 250 V, 500 V and 1000 V MIT410 50 V, 100 V, 250 V, 500 V and 1000 V + PI, DAR MIT420 50 V, 100 V, 250 V, 500 V & 1000 V + PI, DAR and result storage MIT430 50 V, 100 V, 250 V, 500 V & 1000 V + Bluetooth download MIT40X 10 V to 100 V in 1 V steps INSULATION TESTING n Test voltages - 250 V to 1000 V or 50 V to 1000 V insulation test voltages available n Test Lock - Locks insulation test on continuously. n Test voltage display - The actual test voltage is displayed on the smaller digital readout, with the insulation result on the larger digital display. n Analogue arc - The display also features an analogue arc to replicate the response of a moving coil display. n PI and DAR - Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) functions n 200 G½ - Insulation testing from 20 G½ (MIT400) to 200 G½ (MIT420 and MIT430). n Silicone leads - High quality flexible silicone test leads are comfortable to use and prevent measurement errors on higher G½ ranges. n Test inhibit - prevents testing if voltages in excess of 50 V are detected when making insulation tests. n Insulation buzzer - The buzzer can be set to buzz if the insulation resistance is above a preset limit, set via the Setup menu. CONTINUITY TESTING n Auto-test - Auto test on circuit contact enables real two handed operation without the need to press the test button. n 200mA or 20mA - Either 200 mA or 20 mA continuity test currents are available. 20 mA test current will considerably increase battery life. n Lead null - Lead resistance compensation (NULL) operates up to 9.99 ½ of resistance. n Buzzer - ON-OFF selected by simple push button. n Buzzer limit - Continuity buzzer limit alarm provides adjustment of the maximum resistance the continuity buzzer sounds. This is adjustable from 1 ½ to 20 ½ in 5 steps.
