The Megger DLRO200-115 Digital Low Resistance Ohmmeter (DLRO) checks and measures contact resistance in high voltage circuit breakers, disconnecting switches (isolators) or busbar joints. The Megger DLRO200-115 DLRO accurately measure resistances ranging from 0.1μΩ to 1Ω, at high currents.
The alphanumeric keypad of the Megger DLRO200-115 DLRO allows you add notes to stored results, as well as set the test current directly by keying in the value required. The Megger DLRO200-115 DLRO will check the continuity of the test circuit, and will quickly ramp the test current up to the desired level. The keyboard is also used to set upper and lower limits for the result and to prevent the use of excessive currents by setting an upper limit to the allowable test current.
