All-in-one: multi- & milliohmmeter & insulation measuring device & winding test & data logger. The METRAHIT IM XTRA BT is a multi- & milliohmmeter and data logger. Applications can be found in industry in production and in the test field as well as in service in electrical engineering and in mechanical and vehicle construction. An all-in-one device with 30,000 digits: milliohm and multimeter, data logger and insulation resistance and winding tester. Compact and multifunctional for field use: Can be used just as advantageously in the aircraft cockpit as in other cramped measuring locations where otherwise several individual devices have to be used. Milliohm measurement with 4-wire connection (Kelvin measurement) with 200 mA or 1A Insulation tester with test voltages from 50 to 1000 V Short circuit test with 1000 V test voltage High-end TRMS multimeter with 100 kHz bandwidth. Safety-relevant tests for electrical devices, drives and installations with just one field-compatible deviceHigh-voltage system test according to UN ECE R100Insulation resistance measurement according to EN 61557-2 / VDE 0413-2Rlow installation test according to EN 61557-4 / VDE 0413-4Bonding test or potential equalization measurement, e.g. on the outer skin of the aircraft (lightning protection - discharge test/'wick test'). The multimeter is a portable, extremely robust multi-meter designed for field use. It is suitable for maintenance, service and diagnosis of electrical machines or drives and systems, e.g. in the automotive, avionics, energy or automation sectors.The all-in-one device is an insulation tester, milliohmmeter, short circuit tester and universal multimeter. It is ideal for safety testing and diagnostics on electric and hybrid vehicles as well as all types of electrical machines. In conjunction with an optional coil test adapter, it enables short circuit measurements.
