The Megger DLRO10HD Dual Power 10A Low Resistance Ohmmeter allows for high or low output power selection for condition diagnosis and features a rechargeable battery or line power supply, continuous operation, even with dead battery. 10 A for 60 seconds, less time waiting to cool, great for charging inductance. The high input protection to 600 V has an inadvertent connection to line or UPS voltage will not blow a fuse. The heavy duty case features an IP 65 lid closed and IP54 operational (battery operation only). A rotary switch selects one of five test modes, including auto start on connection, giving ease of use. Equally at home in the laboratory, the workshop or in the field, on the bench or on the ground, Megger’s new heavy duty DLRO10HD low resistance ohmmeter combines rugged construction with accuracy and ease of use. It features an internal rechargeable battery and can also operate from a mains supply, even if the battery is completely flat.
