Megger DLRO200 Low Resistance Ohmmeter


Megger DLRO200 Key Features:

  • Small and weighs less than 15 kg (33 lbs)
  • Test currents from 10 A to 200 A d.c.
  • Measures resistances between 0.1 μΩ and 1 Ω, at high currents.
  • 0.1 μΩ best resolution
  • On board memory for up to 300 test results and notes
  • Add notes to any stored result by using the on board alphanumeric keypad
  • A large liquid crystal display
  • RS232 port to download stored results or for real time output to a printer
  • Supplied complete with 5m (16.4 ft.) test leads and download software
  • Smooth, continuous applied current eliminates magnetic transients capable of inductively tripping breaker controls (115 V version)


Megger DLRO200 Test Modes:

DLRO200 operates in one of three modes, which are simply selected from the on screen menu.

CONTINUOUS mode is provided for users who wish to monitor a resistance over a period of time.  Connect the test leads, select the test current and press the TEST button. DLRO200 will pass a current continuously, and measure the resulting voltage at 2- second intervals, until the test button is pressed to stop the test or the test circuit is interrupted.

In NORMAL mode you connect the leads, select the test current and press the TEST button. The test current will ramp up to the desired level, hold for 2 seconds and then ramp down. The whole process  takes approximately 10 seconds.

In AUTO mode select the desired current, connect the current leads and press the TEST button. The TEST lamp will flash to show that the DLRO200 is ready to carry out a test. As soon as the potential leads are connected, a test will start. To repeat a test, simply break contact with the voltage probes and remake contact.

Measuring individual joints in a busbar is a good example of the convenience to  be  gained  by  using  AUTO  mode. The two current leads are connected to the ends of the busbar.  They will remain connected here until all tests have been completed. When the voltage leads make contact across a joint, DLRO200 detects that all four leads are connected, carries out a test and stops. When you move to the next joint DLRO detects the new completed circuit automatically and carries out the next test, and so on until all joints have been tested.

The results may be stored automatically and may be recalled to the display or downloaded for review.
