MT03A, Milliohm and Electric Motor Tester Kit

A complete 3-phase motor winding resistance test in less than one minute!
The MT03A Milliohm & Motor Tester from Pico Technology is a revolutionary device capable of changing the way low-resistance testing is performed.
The MT03A offers resistance testing of all windings on a 3-phase electric motor in under a minute, producing highly accurate results that can automatically compensate for temperature using the included sensor.
It is a PC-hosted measuring device that must be connected to a PC via the USB interface during measurements and is operated using the software supplied.
Designed to meet the needs of technicians and engineers in a wide range of industries, including automotive, off-highway, heavy-duty, industrial, marine, rail, mining, heavy equipment, access machines, and renewable energy, the MT03A is the ultimate low-resistance testing tool.
With its earth-bond testing in compliance with UN ECE R100 regulations and a minimum test current of 200mA, the MT03A has widespread applications, including fuel pumps, vehicle electric motors, air-conditioning motors, regeneration pumps, blower motors, camshaft controls, EGR valves, turbo actuators, and more.
This innovative device works according to the 4-wire Kelvin measurement and is also perfect for checking grounds to ECUs, earth straps, starter motor cables, safety grounds, weld contact quality and earth bond testing, thus everywhere where high-precision low-impedance measurements have to be made.
The MT03A has a USB port for easy connection to a PC, without needing any external power supply, and comes encased in a durable rubber boot with a hanging bracket for ease of use, while the included S-hook allows for effortless mounting in the working area.
The dedicated Windows software application provides a clear user interface that provides simplicity, speed, and complete control over the tester. The highly accurate milliohm values can be automatically temperature-compensated, and the MT03A ensures precision and reliability even in varying temperature conditions. The Kelvin clips are also included to minimize contact resistance effects when connecting the measurement unit to the component under test
