Measure Low Resistance with the Megger DLRO10HD and Prevent Long Term Damage

Megger DLRO10HD Digital Low Resistance Ohmmeter The operation of electrical equipment depends on the controlled flow of current within the design parameters. When increased demands are placed on various aspects of the electrical circuitry, low resistance measurements are recommended to prevent long term damage to existing equipment and to minimize energy wasted as heat.

Low resistance measurements can help indicate any restrictions in current flow that might prevent a machine from generating its full power, or insufficient current to flow where activation of protective devices could be restricted as a result of a fault.

Periodic tests should be made to identify unexpected changes in the measured values, and the trending of this data helps indicate, and may forecast possible failure conditions.  Excessive changes in measured values point to the need for corrective action to prevent major failure.

The Megger DLRO10HD 10A Digital Low Resistance Ohmmeter is a heavy duty model that combines simplicity of operation with selected high power ranges.

 

Rated to IP65 with the lid closed and IP54 when operating from battery power, theMegger DLRO10HD provides significantly enhanced compliance, and  is capable of delivering 10 A while measuring up to 250 mΩ and 1 A while measuring up to 2.5 Ω. In the high current 10 A mode test current is maintained for up to 60 seconds. The use of a four terminal measurement technique removes the test lead resistance from the measured value. Test lead contact is monitored before and during a test to reduce the chance of erroneous readings.

The Megger DLRO10HD provides five test modes each of which is selected via a rotary switch, and controls are simple and easy to operate in all weather conditions.
