Product description Compact and weighing less than 15 kg (33 lbs) Test currents from 10 A to 600 A DC Highest resolution of 0.1 μΩ Built-in memory for 300 test results and notes RS232 port for downloading saved results or real-time printing Megger DLRO600 is a micro-ohmmeter capable of measuring resistance from 0.1 μΩ to 1 Ω at high currents. This versatile device can provide test currents from 10 to 600 A DC depending on load resistance and supply voltage, utilizing four-wire measurement technique to eliminate lead resistance.
The unique design of DLRO600 minimizes weight and size — the device weighs less than 15 kg. Its compact size makes it useful in various environments, and its high current capacity and small form factor make it suitable for testing circuit breaker contacts, switch contacts, busbar connections, and other high-current applications.
A large LCD screen displays all necessary information for testing; all test parameters and measurement results are shown. Additionally, 300 result sets can be stored in the built-in memory for later download to a PC or direct printing via the RS232 port. Notes can also be added to saved results using the built-in alphanumeric keyboard, facilitating further identification. This keyboard also allows direct setting of the test current by entering the desired value. DLRO600 will verify circuit continuity and quickly increase the test current to the required level. The keyboard is also used to set upper and lower result limits and prevent overcurrent usage.
