Digital microhmmeter DLRO100 series

portablelow-resistancebattery-powered

Perform high current low resistance testing in almost any location, even if there is no access to a mains supply The DLRO100 series delivers a test current up to 100 A DC to measure resistance from 0.1 μΩ to 1.999 Ω with a resolution of 0.1 µΩ The DLRO100 series of digital low resistance micro-ohmmeters are portable, lightweight instruments that can deliver a test current of 100 A. They can be supplied with internal rechargeable Li-ion batteries that provide sufficient power for up to 200 manual/automatic tests on a single charge. This degree of autonomy makes it easy for you to perform high current low resistance testing in almost any location, including areas without access to a mains power supply. To ensure dependable operation even in the most demanding environments, the DLRO100 instruments use novel circuitry that gives high noise immunity and guarantees stable readings. For physical protection, they feature enclosures with an IP54 ingress protection rating even when the lid is open and testing is in progress. Operator safety in adverse conditions is assured by a CAT IV 600 V safety rating in line with IEC 61010. With an optional DC clamp, dual ground operation is also supported. DualGround™ greatly enhances safety when working in substations and similar environments by allowing tests to be carried out with both sides of the equipment under test grounded. DLRO100 instruments have a wide range of applications, including checking the resistance of busbar and cable joints, measuring wire and cable resistance, and verifying lightning conductor bonding.
