Megger DLRO200 Micro-ohmeter

The Megger DLRO200 Micro-Ohmmeter is a state-of-the-art device designed to deliver high-accuracy resistance measurements in electrical systems. Weighing less than 15 kg, this compact instrument is perfectly suited for use in various environments, including field applications, production floors, and workshops. Its portability is a key feature, facilitating easy transportation and use in different settings without compromising performance.

Capable of generating test currents ranging from 10 A to 200 A DC, the DLRO200 is a versatile tool that adjusts to the specific requirements of each test, subject to load resistance and supply voltage. This adaptability makes it ideal for a wide array of applications, particularly in testing connections such as circuit breaker contacts, switch contacts, and busbar joints where high current is necessary.

One of the standout technological features of the DLRO200 is its four-terminal measurement technique. This advanced method significantly enhances measurement accuracy by eliminating the potential error caused by the resistance of the test leads. The DLRO200 achieves a remarkable resolution of 0.1 µΩ, ensuring precise and reliable readings across a range from 0.1 µΩ to 1 Ω at high currents.

Megger DLRO200 Micro-ohmeter specifications:

  • Power Supply for DLRO200 for full output (unsmoothed DC) 100 to 265 V 50/60 Hz with a load less than 19 mΩ (supply >207 V rms), or 11 mΩ (115 V rms) including current leads.
  • Test Modes Manual, Auto, Continuous.
  • Range 0.1 μΩ to 999.9 mΩ (subject to supply voltage and leads used).
  • Data storage and communication:RS-232 port
  • Max output current (DC):200 A
