Megger MTR105X Offers

The MTR105X combines several common motor-test functions into one handheld device, reducing setup time and simplifying field or workshop diagnostics.

For reliability teams, it supports preventive maintenance by helping identify insulation degradation, winding imbalance, poor connections, and rotation issues before they lead to costly failures. Megger specifically highlights diagnostics such as temperature compensation and polarisation index testing for identifying motor problems before breakdowns.

For reporting and asset management, the MTR105X Bluetooth connection is the key advantage over the standard MTR105. It can stream results to CertSuite Asset, store results against specific motors or generators, support repeat testing, and help trend results over time. It can also still be used fully as a standalone tester without CertSuite.

Features

  • Resistance range 100 Ω up to 200 GΩ
  • Supports PI, DAR, Timed and Temperature Compensation
  • Stabilised insulation test voltage with -0%/+2% ±2 V accuracy, including selectable nonstandard test voltages from 10 V to 999 V
  • Adjustable resistance limit buzzer settings for insulation and continuity testing
  • Measures AC 10 mV up to 1000 V; DC 0 to 1000 V; TRMS (15 Hz up to 400 Hz)
  • Tests three-phase supply, phase sequence, and motor direction of rotation, with results displayed on screen
  • Single automatic resistance range from 0.01 Ω to 1.0 MΩ
  • Automatic test current selection, including 200 mA continuity testing up to 4 Ω
  • Lead resistance compensation (NULL) operates up to 10 Ω of resistance
  • Selectable auto/manual testing with single-direction or bi-directional test modes
  • Automatic inductive, capacitive, and resistive testing, with selectable inductance/capacitance modes and 120 Hz or 1000 Hz test frequency
  • Full colour graphic display
  • Guard terminal, to eliminate any surface leakage current
  • Detachable test leads with interchangeable clips and probes for different applications
  • CertSuite LITE and BLE enable real-time testing and reporting with onboard storage and secure wireless connectivity
  • Stores up to 256 motor results with date/time stamps and can download results to USB for reporting
  • Environmental protection to IP54, providing protection against moisture and dust ingress, including the battery and fuse compartment
  • A ‘rubber over moulding’ combines a tough shock absorbing outer protection with excellent grip, on a strong modified ABS housing, providing a robust case
  • Rechargeable batteries with mains charger kit option
  • Designed for CAT III 600 V environments with live-voltage detection and test inhibit to reduce risk when connected to energised circuits

Applications

  • Testing, troubleshooting, commissioning, and maintaining electric motors and generators
  • Checking motor winding insulation
  • Comparing phase-to-phase winding condition
  • Verifying low-resistance connections
