Megger Baker MTR105 multifunction motor tester

The Megger Baker MTR105 handheld motor tester is designed and built for performing multifunctional tests on motors, all in one device. Features include an insulation resistance tester, a DLRO (digital low resistance ohmmeter), a voltmeter, a motor rotation tester, an LCR meter, a low resistance ohmmeter, temperature measurement, environmental protection and safety ratings.

The device features a guard terminal to eliminate any surface leakage current, which is said to ensure correct results. It is encased in rubber overmoulding, which combines tough shock-absorbing outer protection with good grip in a strong modified ABS housing. It also includes detachable test leads with interchangeable clips and probes for different applications.

The unit comes with a full graphic display and rotary dial control. It can save test results for up to 256 motors and offers a USB storage option. It can be operated on rechargeable batteries.

The product is IP54 rated, which makes it capable of providing protection against moisture and dust ingress — including the battery and fuse compartment. It is also CAT III rated 600 V (up to 3000 m), which should make it safe to use.
