Delivering precision results in less than three seconds, Megger is offering their DLRO10 1006-598 Digital Low Resistance Ohmmeter. The DLRO10 1006-598 chooses the most apt test current, up to 10A DC to measure resistance from 0.1µΩ to 2000Ω on one of the seven ranges. The ohmmeter is equipped with a Normal, Auto, Continuous and Inductive Measurement Modes. Utilizing forward and reverse current, the average of the measurements attained is displayed to a basic accuracy of 0.2%.
The DLRO10 1006-598 is suited with an expansive, vivid 4 1/2 digit LED display for the best visibility in all lighting conditions. Megger has supplied the instrument with a pair of duplex handspikes with 1.2 m (4 ft) leads for user safety and an interchangeable NiMH battery pack for efficiency. Automatic continuity detection, visible alerts of high voltages and current flowing in the test sample and an array of other features and functions all make Megger’s DLRO10 1006-598 a leading example in low resistance measurement.
