Megger DLRO2 Hand-Held 2 A Low Resistance Ohmmeter

The Megger DLR02 or DLRO2X is a great addition to your toolbox!

Helping you find the difference...

Megger DLRO2 is a tough, handheld, intuitive Low Resistance Ohmmeter boasting NEW functionality. When testing multiple connections there could be micro-ohm differences which may not show when using a continuity tester; instead of taking several measurements the new ‘Difference‘ meter enables you to compare multiple results visually with an initial measurement to see the percentage difference in your results. The ‘Difference‘ meter also translates the percentage difference to a needle/pointer movement, making the changes clear to see change. New reference measurements can be set at the push of a button. The ‘Difference‘ meter can highlight issues before the fault occurs, making it perfect for your preventative maintenance regime.


Colour display with new ‘Difference‘ Meter:

Includes the ‘Difference‘ meter for quick data comparisons on several connections

  1. Difference Meter scale
  2. Previous result markers in red indicates noise was present
  3. Reference measurement
  4. Previous result markers
  5. Electrical noise warning
  6. Percentage difference between current measurement and initial reference measurement

Megger DLRO2 Key Features:

  • ‘Difference Meter’ for quick data comparisons
  • Use long leads at 1 A without compromising test speed
  • Safely test the resistance of inductive loads at 1 A
  • <600 V active protection against inadvertent live connections without blowing a fuse
  • Ideal for outdoor use with protection against dust and moisture to IP54
  • Industry standard safety rated at CATIII 600 V/CATIV 300
  • Easily select functions using the rotary dial
  • Option to run the test in bidirectional mode or in unidirectional mode to save time and battery power
  • The ability to view 3 results on the screen at any time makes it ideal for 3-phase systems
  • Overcome the effects of standing EMF voltages using the bidirectional test mode
  • Forward and reverse results can be viewed on the secondary display
  • For stability of results, the instrument will warn you when electrical noise, or noise from poor clip/probe connections, is present
  • Keeps testing as long as you can, with as many as 500 x 2 A - 3 second tests from a full charge
  • Supplied with compact CATIII 600 V/CATIV 300 V rated kelvin clip test leads


What extra do you get with the DLRO2X?

  • Noise Rejection mode with Confidence Meter (DLRO2X only)
  • Manual and auto save results for export to USB (DLRO2X only)


Megger DLRO2X Extra Features:

Now you can easily identify if your measurement is being affected by noise... via the display‘s high noise indicator (when using the following modes: normal, long test lead, inductive). If a measurement is being affected by noise the results may not be reliable; to compact this situation the DLRO2X is equipped with a noise rejection test mode.

In this test mode, the current is passed continuously, and in one direction only, before feeding a stream of measurements into the Megger patented ‘Confidence Meter‘. The measurement is then refined until a stable, accurate measurement is obtained.

The DLRO2X can save results to its internal memory. Folders can be created to store results for each asset ID.

When the test is complete, the results can be manually saved to a chosen asset ID or the user can utilise the Auto Save function which can be set up so that all results will automatically be saved to a specified folder once the test has completed. These results can then be copied to a USB data stick to transfer to your PC.
