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 DLRO that can supply 10 amps of current at 250 milliohms resistance (AVO DLRO)
Combining simplicity of operation with a rugged IP65 case, the Ohmmeter is designed for stable ground and bench operation, and is powered from either its rechargeable battery or line power, is suitable for continuous testing in production line/repetitive use environments.
TheMegger DLRO10HD features rotary switch controls that are simple and easy to operate in all weather conditions, with gloved hands, and a large clear, backlit LCD display that is easy to read from a distance.
Providing significantly enhanced compliance, the Ohmmeter, is capable of delivering 10 A into measurements up to 250 mΩ and 1 A into measurements up to 2.5 Ω. The duration of each test may be up to 60 seconds.
Rated CAT III 300 V, theMegger DLRO10HD offers a range of test leads available to suit the application, and provides five test modes each of which is selected through a simple rotary control.
