Product overview 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 loading saved results or real-time printing Supplied with 5-meter measurement leads and download software Megger DLRO200 is a 200 A micro-ohmmeter that measures 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. DLRO200 also employs a four-wire measurement method to eliminate lead resistance from measurements.
The unique design of DLRO200 minimizes weight and size—less than 15 kg. Its compact size makes it equally suitable for workshop, manufacturing site, or field use, and its high current capacity and small form factor make it ideal for testing circuit breaker contacts, switch contacts, bus connections, and other high-current applications.
A large LCD display provides all necessary information for testing; all test parameters and measurement results are shown. Additionally, 300 result sets can be stored in the internal memory for later download to a PC or direct printing via RS232 port. Notes can be added to any saved result using the built-in alphanumeric keyboard, simplifying subsequent identification. The keyboard also allows direct setting of the test current by entering the desired value. DLRO200 will then verify circuit continuity and quickly increase the test current to the required level. The keyboard is also used to set upper and lower limits for...
