DESCRIPTION A sigificat additio to the comprehesive rage of Megger Low Resistace Ohmmeters, DLRO100 eables low resistace measuremet, across multiple applicatios, i areas without access to mais power. The itegral Li-io battery supplies a costat 100 A curret for up to 200 Maual/Auto tests to eable ehaced productivity i remote locatios. With a focus o user safety, advaced desig features esure the safe operatio of the istrumet i the most adverse coditios, icludig a CAT IV 600 VAC / 500 VDC safety ratig i accordace with IEC The rugged desig, ituitive iterface ad IP54 (lid ope) ratig esure reliability ad ease of use i the most arduous of coditios. Test Leads: Stadard test leads, with separate Curret & Potetial, or Kelvi, combiig both Curret & Potetial i oe clamp, are available as optioal accessories i 5 m, 10 m & 15 m legths. All test leads are CAT IV 600 VAC / 500 VDC safety rated. Test Modes The Maual test mode allows the user to iitiate the test procedure oce the probes are i cotact with the object uder test. Oce the TEST butto is depressed the TEST lamp will illumiate ad the istrumet will udertake a sigle test to verify the resistace of the test object. I Auto mode the user selects the desired curret, coects the curret test leads ad as soo as the potetial leads are coected a test will start automatically. To repeat a test, simply break cotact with the potetial probes ad remake cotact. I Cotiuous mode the user coects the test leads ad presses the TEST butto, iitiatig the test procedure. The istrumet will cotiue to test, updatig the display after each ew test cycle, util the TEST butto is pressed or the test procedure times out. A ew tough adjustable clamp has bee desiged to esure flexibility i may applicatios ad provides a good coectio with the test piece. History of Ducter testig For over 100 years the Ducter test has bee used to describe a simple test for measurig very low cotact resistaces ad Ducter, which is still used as a trade mark, was the ame origially give to the low resistace ohmmeter maufactured by Megger. The ame Ducter was registered by Megger i Jue 1908 ad Ducter has sice become the idustry stadard.
