Compact and weighs less than 15 kg Test currents from 10 A to 200 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 Supplied with 5-meter measurement leads and download software
The Megger DLRO200 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 200 amperes DC depending on load resistance and power supply voltage. It employs a four-wire measurement method to eliminate lead resistance from measurements.
The unique design of the DLRO200 minimizes weight and size—less than 15 kg. Its compact size makes it equally suitable for workshop, manufacturing site, or field use. It is ideal for testing circuit breaker contacts, switch contacts, busbar connections, and other high-current applications.
A large LCD provides all necessary testing information, displaying test parameters and measurement results. Up to 300 result sets can be stored in the internal memory for later download to a PC or direct printing via RS232. Users can add notes to any saved result using the built-in alphanumeric keyboard, simplifying result identification. The keyboard also allows direct setting of the test current by entering the desired value. The DLRO200 then checks circuit continuity and quickly ramps up the test current to the required level. The keyboard is also used to set upper and lower limits for testing.
